This is the correct way to adjust front camber on the 5th Gen. One the alignment machine with the clevis bolts loose turning the camber screw tighter (Righty Tighty, Lefty Loosy) will push the knuckle away from the strut. Loosening the camber screw allows the knuckle to fall in toward the strut. It is a 10mm 1.5 pitch thread.



Your alignment shop may have a T.O.M.C.A.T. Air-Assisted Multiple Camber Adjustment Tool air bag. It fits between the wheel and the strut and works in the same way as the camber screw. Inflate (Righty Tighty) the bag to push the knuckle away from the strut or deflate (lefty Loosy) the bag to allow the knuckle to fall into the strut. If they don't, they have a guy that can push or pull on the wheel while they tighten it. Never, ever use those lame camber eccentric bolts on a Camaro. EVER!



Anyone that tells you different, have them call me

Pedders foundation as a company is more than just a range of bits, we are Suspension specialists committed to delivering a Pedders Driving Experience. A lowered vehicle should have a full range of alignment adjustments. The Camaro delivers from Chevrolet with a fixed Castor position. The radius arm bolts into round holes with no available adjustment. Front Camber is adjustable from the factory. There is a threaded hole for front Camber Adjustment Bolt / Screw, but no bolt is installed and no part number is listed by Chevrolet. The rear OEM eccentric adjusters for Toe and Camber provide approximately one degree adjustment range. For an alignment specialist, this is unacceptable. You want to get your Camaro perfectly setup. This is what Pedders is all about. Our solution is a set of cadmium plated eXtreme Alignment Bolts. While GM made the hole round for the front Castor Adjustment or lack thereof, they did weld in brackets for an eccentric to work against. Your local Pedders Dealer can create a slot to provide Castor adjustment with Pedders Camaro Alignment Bolts. The kit provides the front Camber screws that GM didn't.



For the 5th Camaro, GM decided to produce the front sub-frame with only a round hole, but they kept the 'fences' for caster adjustment with eccentric bolts just like th Pontiac G8 and Holden Commodore. The slots to allow adjustment were lost in translation. For a performance driver, a vehicle without full alignment adjustment capability feels like driving with one hand tied behind your back. Pedders made the decision to make the Camaro front suspension fully adjustable.

Stock Radius Bush Mounting area with a round hole and adjustment 'fences'.



Step one requires the technician to drill two holes in the bracket.



Step two requires CAREFUL GRINDING. We use the two holes to make the grinding process more accurate while the technician creates a slot. The eccentric that will be used does not reach all the way to the bracket sides so a bit of excess metal is not an issue. The technician can check the clearance with a Pedders Castor Eccentric Bolt as they grind to make sure the fit is Pedders Perfect.



When assembled the Cadmium plated eccentric allows the alignment technician to increase or decrease Castor. A fully Pedderised Camaro with good tires will not require ANY BIAS in the alignment. We can do a road course style alignment and your Camaro will not pull. This is because the Pedders component have made the suspension more stable by reducing excess motion. Should your Camaro be tweaked and develop a pull the same Pedders Castor Eccentric Bolts can be used to create a bias to correct the pull. We strongly recommend that before you alter your alignment due to a pull that you have a qualified technician, because the machine is only as good as the tech, check your tires on a road force balance machine to make certain the pull is not induced by a tire. We will adjust them on the alignment rack. Here is the installed eccentric.



Alignments are Pedders core business so we decided to make the front camber screw part of the Camaro Alignment Bolt Kit. To install the Pedders Front Camber Screw it is essential that you use LocTite Blue. The Camber screw will never bear a load while driving, but we want to make certain they never vibrate out. LocTite Blue is ideal for this.



Pedders Rear Eccentrics are virtually bullet proof with approximately 2 degrees or double the factory adjustment. With the Camaro alignment Kit installed your Camaro can be setup for the drag strip, road course, auto cross or every day flawless driving. Even better, Pedders alignment eccentric bolts carry a unique warranty feature. Should a Pedders eccentric ever fail while you own the vehicle we will replace it. You get a superior alignment, improved driving experience and a life time warranty with Pedders Camaro Alignment Bolt kits.

To get the aggressive alignment we prefer Pedders Full Camaro Alignment Kit is required. They increase the adjustment range by 1 degree or in layman's terms a lot. We achieve this result my moving the eccentric to the outer edge of the bolt. The eccentrics are cut on a water jet, assembled in a jig and welded. This is a time consuming process. To finish the bolts we have them cadmium plated.



Eccentrics have a bad habit of drifting under high loads. We address that with more material. We make our eccentrics out of stock that is much thicker than the OEM bolts. More material means more strength and improved holding power.



We use a thick 'holding' nut and a thin jam nut. Unlike quenched nuts, you can use these again and again.



Taking the performance of your 5th Gen and alignment to the next level requires the use of Pedders Dual Bearing Camber Plates. With the stock front struts or Pedders coilovers you can achieve -2.2 Degrees of front camber. Relieving the upper slot in the strut to allow it to fall in a bit more will get you to -2.5. When running high negative camber it is Mission Critical to check spacing between the inner tire sidewall and the strut or coilover. We use a standard #2 lead pencil as a gauge. If the pencil passes between the tire and the strut or coilover you are good to go. With Pedders Dual Bearing Camber Plates we suggest you run them full in, maxed out for negative camber. Positioning the stut top well in toward the engine improves SAI. Your 5th Gen will drive better. Final adjust the negative camber at the knuckle using the camber adjustment screw.

Bush Timing

Step 1. Lift the car on a two post lift and raise it.

Step 2. Loosen the following bolts/nuts:
Front:
---Inner Control Arm Bushing
---Inner Radius Rod
Rear:
---Trailing Arm Bushings (both ends)
---Toe Rod Bushings (both ends)
---Lower Control Arm Bushings (Inner)
---Upper Control Arm Bushings (Rearward)
---Lower Strut Bushings

Step 3.
Lower the car and drive it around the parking lot SLOWLY and on to the alignment lift.

Step 4.
With the weight of the car on the wheels tighten all of the nuts/bolts to spec.

Step 5.
Align the car at the new ride height.

Front and Rear Bolt Torque Values




NOTE: Torque specifications that read XX torque value and XX degrees are usually TTY and require replacement of the bolt, nut or both. If replacement parts are not available from GM the minimum acceptable torque will be those values stated along with a liberal application of a thread locker i.e. LocTite.

Too bad the Z/28 doesn't have these.

It is raining camber plates!!!!!





They are now officially in-stock ready for immediate delivery!

Pedders 581050 Camaro-Dual-Bearing-Camber Plates

1.9 Degrees of Additional Negative Camber Adjustment
18mm Thick Monster Plate
Dual Bearing Configuration
Banded Thrust Bearing for Strut Rotation
Large Monoball for Strut Articulation
Fits All Brands of 5th Gen Coilovers

Pedders 5th Gen Camaro Dual Bearing Camber Plates with an 18mm Thick Main Plate are configured with a banded thrust bearing for coil rotation when turning and a large monoball for strut articulation. Pressed into the upper aluminum spring perch is a banded sealed thrust bearing. The thrust bearing replaces the OE strut bearing and delivers silky smooth operation.

A large monoball allows the strut to articulate without bind. This precision assembly delivers an additional 1.9 degrees of negative camber. Each mark on the camber plate is .25 degrees of adjustment. Combine the adjustment of Pedders Dual Bearing Camaro Camber Plates with the OE knuckle / clevis camber adjustment to achieve more than -4 of camber on demand. As a side benefit, the Steering Angle Inclination (SAI) improves as more camber was added from the plates.

IN-STOCK for IMMEDIATE SHIPMENT!

Pete,
I think that Pedders did a Home run by fitting the Camaro with 305/30ZR19 tires. Did you also tried the 19X11 fronts and 19X11.5 rears wheels setup like on the '14 Z28? (I see that you went with 19X10.5 on your project car).

Can it be possible to go with those tires, upgrade sway bars, but just to go with new springs, and use the stock shocks (without going the coil over way), just to save some $. Do you think that it might improve the handling on the track?.

Forgeline can now fit 19x11s all around. I prefer the true square to the semi square Z/28.

You can run the 305 setup with stock springs and shocks because the unsprung weight is reduced. You do get better results with the higher spring rates available if you go coilovers.

The HUGE benefit is a dramatic reduction in understeer from just the wheels and tires. Sways, bushes and coils are all plus add ons.

Yes a square setup probably makes more sense. Do you prefer 19X11 or 19X11.5 (all around) with those tires?
With that set up which of your sway bars do you recommend?.

You did a great job with the Camaro. Congrats!!

PS. Right now I'm looking to replace my Mustang probably with a 1LE. I will contact you when I do that. Thanks!

I like how you think. Forgeline 19x11 DP3R full competition wheels are my weapon of choice.

When you get your 1LE we change out the sub-frame and radius bushes along with the 1LE rear balance bar. Those foundational level changes make a HUGE difference in the 1LE and we can build from there.

Pete, yes you do gotta love the square 305/30/19 setup!!!

Its funny because last weekend i re-installed my OEM wheels and tires for the trip down to Houston to get PatG to finalize my tune on the new motor. The car just did not feel nearly as nimble/responsive in those 900 miles. After adding the Pedders setup back on i was happy once again! I was able to fix the leak in the wheel by scraping out the old seal and re applying a bead of 3M window weld to the wheel. Had to let it cure....this is why i had to reinstall the monster truck wheels and tires.

Anyway, i am ready to order the 12kg coils, ZL1 rear bar and control arms, end links, and camber plates.

Question: Have Heath and co. at American Muffler and Brake done the camber plates yet...and when its all said and done how should we set up the alignment????

Thanks Pete!

2013 Strut Mounts, Pedders Coilover Pre-Compression and Ride Height Settings

The 2013 5th Gen delivers with a revised strut mount. The upper portion of the mount appears to be unchanged, but the lower mount and bearing have changed.



The redesign has nothing to do with any strut noises in our opinion. It is possible the driver was cost reduction. The revision to the steel and urethane insulator (the steel plate is wider and flatter) distributes load without the need of an additional plastic seat (the gray plastic on the older style mount).



The dimensional change required an adjustment by Pedders to our billet aluminum coil to OEM mount adapter plate. The 2013 plate has a larger I.D. center hole and is a bit taller. The 2010 - 2012 billet plate mounts directly to the OEM bearing / mount. The 2013 uses the OEM steel and urethane insulator.



Here is the Xa and Supercar coilover stack assembly process. It starts with the coilover, bumpstop, boot and washer.



Slide them on in that order.



Add the coilover spring.



Next we add the OEM mount. The gold tone washer is supplied by Pedders and replaces the OEM washer. We have already added it to the assembly stack, but show it here to make the process more clear. The black plastic coil insulator goes to the spring side of the billet aluminum adapter plate and directly to the OEM mount for 5th Gens made between 2010 and 2012. On the top side of the OEM mount we re-use the OEM black conical washer and 24mm jam nut.



The completed assembly looks like this.



The ONLY difference for a 2013 is that we re-use the OEM urethane and steel insulator. The complete assembly looks like this.



The top view for all years looks just like the OEM assembly.



The coilover stack is a bit different when using our new Dual Bearing Camber Plates. Discard the gold tone washer supplied with your Pedders coilovers. All you'll use in the assembly stack are the bumpstop, boot, plastic coil insulator, lower spring perch with banded thurst bearing, the camber plate and special nut supplied with the camber plate.



The assembled coilover with dual bearing camber plate looks like this from the side.



And this from the top.



How easy is that? Our next challenge is to make setting coil pre-compresion and ride height before installing the coilovers on your 5th Gen as easy as the assembly.

Setting the pre-compression on the coils is mission critical. Too many installers fail to read the directions because they 'know' how to adjust a coilover. When you lower a car by lowering the spring perch you lose suspension travel and compromise ride quality and handling. Bouncing off the bumpstops is not good in a high speed turn on a track. Let's get it right. Anyone care to watch the video?

Caution: This is a purely technical How-To. Grab an Double espresso before watching.



When you know how to do it right, it really is easy. When we did an install on Glen's 1LE at BlackJack Speed Shop we scaled the car before and after.



First, how great are the straight from the factory weights at each corner of the 1LE!?! Kudos and well done TEAM Chevrolet.

With Glen in the 1LE and a 1/2 tank of fuel the 1LE is track ready at 4131 stock. After adding Pedders 1LE 32mm rear balance bar, radius bushes, sub-frame bushes, front adjustable length endlinks and Pedders Supercar coilovers the 1LE is 5 pounds lighter. The ride height deviation side to side total on the stock coils is 12mm. Setting the coil pre-compresion and ride height as shown in the video the Supercar equipped 1LE has a total ride height deviation of only 3mm.

The front side to side difference in weight is reduced from 34 pounds factory to 21 pounds Pedderised. In the rear the OE difference is 50 pounds and the Pedderised difference is 56 pounds. There is a difference between scaling a car to identify the weight load at each wheel and corner-weighting when we adjust ride heights to balance out the weight at each wheel. We did not have time to corner weight Glen's 1LE.

We did have time to align Glen's 1LE with his dual bearing camber plates. Glen has a conservative daily driver alignment and an aggressive AC / Road Course alignment built in. By loosening four set screws at each of his front camber plates we can drop into street or track mode in a matter of 15 minutes. We added to additional holes to make the plate adjustment easier.



Glen will get them painted so the install looks super clean. Next take a look at the differences between Glen's drive to the track and don't wear out my tires street alignment and his ready to race alignment.



Trackside was add Negative Front Camber and Tow Out. We can add a LOT and then pull it back to the conservative street specs. The next time we work on Glen's 1LE we'll add caster bolts front and camber bolts rear. This will give us a greater range of adjustment to dial his already great handling 1LE in even more.

We hope this post makes you Pedders Coilover and / or Camber Plate Installation easier and more accurate.

Hi Pete.
The latest additions to the "book" are great. I enjoyed the set-up video for the coilovers. Is this the way the V8 SuperCars on a G8 should also be set for initial spring pre-load?
