Suspension Help - BMR

[TwentyTen2SSRS]

Hello! Longtime Camaro5 member when BMR was very helpful and active on here. Not sure they are still a sponsor or not. Have a l of BMR parts but want to get some more information before I make an order.

I have BMR subframe connectors and tunnel brace (yet to be installed) as well as BMR four point strut tower brace, front and rear sway hands (SB039). I have 2010 and have done FE4 upgrade with the updated OEM LCAs with outside bolts that i did same time as sways. My question is I want to also order toe and trailing arms but am unsure which to go with for my setup. Spirited road/mountain driving and occasional road course day or two a year. Mainly want to retain driveability but lose some wheel hop I have currently. I’m hoping toe and trailing would help. Maybe subframe bushings as well? Want to be able to take car on 3-4 hour drives comfortably with my wife. Car has headers, cam, full exhaust and am sponsored by air lift performance so it is on their 3P air suspension kit as well. Anxious to hear your suggestions. Do I upgrade to BMR LCAs as well. Wont need major adjustability as I usually just set it and forget it (see sway bar positions), but open to any help/info thanks!

"I’m hoping toe and trailing would help. Maybe subframe bushings as well?"

Yes - they will.
I went the BMR route and am very pleased with the parts and the way they all work together. My approach was to do all of the parts and installation at once to get a integrated set-up. Def do Rear Cradle Bushings, either high durometer BMR or solid. Also, part of the changing parts is ordering new fasteners, certainly the TTYield or T&Angle bolts as insurance against failure. Lastly, a good alignment from someone who can serve up your desired specs. My parts choice was aimed at aggressive street, and for a heavy car, it handles worlds better than stock. The ride is a little stiffer, but mostly due to the 22" wheels and Coil-Over Settings. I created this build thread back in 2016, and still modding my ride, as it is quite an addiction.

Thanks this is helpful - had no idea on the fasteners as insurance. Right now I’m looking for toe and trailing and the rear cradle bushings. I’d have to take bushing to get installed somewhere - any idea on number of hours to reasonably complete? Have a very trustworthy shop who has worked on my car numerous times bjt like to have an idea before diving in.

In addition have the subframe connectors and tunnel brace ready to install. Recommend doing LCAS as BMR also over OEM FE4 setup? Not sure the benefit there. Have heard others say host control arm z28 bushings as well?


Like you, basically want to do this next round in one shot to avoid multiple alignment payments

BMR Parts:

Rear Trailing Arms (whole arm) TCA026
Need the Bushing which is pressed into the Knuckle:
Rear Trailing Arm Outer Bushings BK006
Rear Toe Rod (Adj Rod Ends) TR004
Full Rear Cradle Bushing Kit (Pro) BK024
OR solid from Pegasus (from Phastek)
As long as the rear is being thrashed on, this makes sense - Rear Upr Cntl Arm Bushings BK039

I'd be guessing at the hours, but a hoist makes the work much easier. I have a Quickjack which is much better and safer than jack stands. So say it takes 20 hours at $50/hr = $1k.

Also - tightening certain fasteners requires a Torque/Angle ratchet wrench adapter, or careful marking on the fasteners to reference how far they were clocked from the initial reference angle starting point. For example, the Upper Control Arm Rear Bushing Bracket Bolts is 59lbft initial, then rotated another 120 degrees.
Any bushing application that rotates (like control arms) must be "timed" when fastened, which simply means the suspension must be at ride height when tightening the fastener. This eliminates any "wind up" in the bushing. I used wheel platforms to do this, the shop must support the wheels on the hoist and not let the suspension hang down.
SO this at the shop:
Bush Timing Method:
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.

I ALWAYS torque stripe the fasteners to verify that they were in fact tightened and check them every year that they do not loosen.

Lastly the Stock FE4 LCA is fine, the BMR piece is prob a stronger piece.

Ive become a big fan of all BMR bushings w/FE4 upgrades (LCA's, sway and shocks/struts. It rides very comfortably but cuts corners like a champ.

Good luck.

No need to get to replace LCA's, I would get Trailing Arms ( TCA026) and Adjustable Toe Rods (TR003). I would also do Cradle Bushings (BK024)
