JP Superior Solutions New Product





5th Gen Suspension Pornography









• Direct Factory Part Replacement
• 1” Drop from Factory Knuckle
• Maintains Original Equipment Control Arm Geometry
• Maintains Original Equipment Suspension Travel
• 100% Compatible with Original Equipment Magnetic Ride Control and Adjustable Suspension Damping
• Supports Aftermarket Coilover Suspension Applications
• Machined from Billet 6061 T-6 or 7075 T6 (solutionized and artificially aged) Aluminum
• Original Equipment Elastomeric Bushings are Replaced with Race Ready Rebuildable Monoballs with Spiral Retainers and O-Rings

The 5th Gen Camaro (2010+) OE knuckles are solid, but come with some limitations. Made of cast aluminum, there are no bushings in the front knuckles. The rear knuckles have sealed monoballs that are not a serviceable part from GM installed for the upper and lower control arms and an elastomeric bushing for the trailing arm. When they wear out, the complete knuckle must be replaced. And they do wear out, as drivers that track their Camaros have learned.

OE Camaro knuckles are essentially the same in function across the range of 5th Gen models, with the exception of the Z/28. The Z/28 has special high durometer elastomeric bushings installed for the trailing arm. Under high load, high heat conditions the standard OE rubber trailing arm bushing soften considerably, which is why the Z/28 uses Tenneco yellow bushings to improve control under all operating conditions.

JPSS 5th Gen Camaro Knuckle Drops are machined from 7075 T6 billet aluminum, which is stronger than cast iron and considerably stronger than the OE cast knuckle. All the OE bushings are replaced by JPSS sealed rebuildable monoballs for optimal control under all operating conditions, regardless of temperature. Cost was not a consideration in the design of the JPSS Camaro Knuckle Drop. Our engineering goals focused on predictable and consistent function regardless of use and track conditions. Once you experience the performance of the JPSS Knuckle Drop, we are confident you will agree we met our goals.

We are huge fans of the 5th Gen Camaro IRS – there is a lot of grip designed in, and it puts down power better mid-corner on than the C6 or C7 Corvette. But, the excellence of the IRS combined with the forward weight bias and narrower front track means that the 5th Gen understeers. The OE Camaro front knuckles use virtual pivot technology similar to a BMW, but the IRS sticks better than the front virtual pivot. Understeer is somewhat reduced on the 5th Gen through semi-square OE wheels and tires, along with more aggressive sway bars on the 1LE and Z/28. Increasing front wheel negative camber would help more, but there is limited adjustment available with OE or aftermarket wheels / tires.

JPSS designed the front 5th Gen Camaro Knuckle Drop with an additional 5mm of track, and modified the position of the upper ear. Together, these changes allow the front strut to lean further in for increased negative camber adjustment. The additional track width helps reduce understeer, even with staggered wheel and tire fitments. JPSS achieves all this while maintaining the symmetry and geometry of the OE arm operation for the virtual pivot front suspension. The OE dust shield installs without modification.

Our experience tracking 5th Gen Camaros since 2009 tells us that lowering significantly improves the car’s center of gravity. Unfortunately, lowering a 5th Gen Camaro with coils or coilovers distorts the range of motion of IRS rear arms and increases rear negative camber. For illustration and discussion purposes, if there is a 6” arc the rear suspension arms travel through, they can move 3” up and 3” down. If you lower the Camaro 1 ½”, the upper arm can only travel 1 ½” up, but 4 ½” down. The upper control arm travel is cut in half before entering a hard stop.

The JPSS 5th Gen Camaro Knuckle Drop lowers ride height by 1” without any compromise of IRS suspension function. Arm travel and arm geometry remain the same as OE, and jounce travel is unchanged. The car’s center of gravity is lowered, but without any compromises in suspension operation. Front track is increased, which reduces understeer, and front negative camber adjustment is significantly improved.

JP Superior Solutions offers only premium performance products that are built without compromises using the finest available materials and components. Each JPSS product is comprised of wear components (like monoballs, O-rings, etc) and non-wear components. Our non-wear components are designed to be almost indestructible. The JPSS warranty is simple: If a non-wear component breaks for any reason other than damage from physical impact, we fix or replace it. All wear components are serviceable, and JPSS sells individual parts and rebuild kits for all our products.

Pete, not trying to over simplify but remember I'm an old G-Body guy. Is this Knuckle Drop part essentially the same concept as a drop spindle?

Because if it is I was wondering why no one made such a thing for the 5th Gen. I actually thought about messaging you about it . LoL

Short answer. The front design is reasonably straight forward. The IRS makes the rear knuckle complicated.

A Knuckle Drop is the best way to lower a modern chassis with an IRS. The engineering behind it is complex. It starts with simple elements of the design process. The 5th Gen Camaro uses steel jacketed sealed monoballs to connect the upper and lower rear control arms to the knuckle. They do not sell them as a repai part. They list a part number, but you can't get them. You could replace them with rubber or urethane, but you lose articulation and performance in altered in relation to temperature.

You'll notice that the OE engineers are using more of the sealed monoball technology. The upper inner rear is the third in the Camaro. The 1LE, ZL1 and Z/28 all use four of them in the toe links. They are growing in use because they operate with precision and do not change properties based on temperature, particularly under high heat. All elastomeric bushings get softer when they get really hot.

The easy way out is to use a spherical bearing. They work in endlinks and in some control arm applications, but geometry prevents their use in the knuckles -- unless you design the knuckle to accept a monoball instead of a rubber bushing or steel jacketed sealed monoball.

I have said for years there are only two kinds of spherical bearings. Those that make noise and those that will make noise. That is still true and why we made the monoballs in our knuckles rebuildable. When they get noisy, change them out for like new quiet operation. We wanted to make sure our monoballs are protected from road debris, so we designed in replaceable O-Ring seals.

I have been thinking about this for years, but never had the right engineering behind me to execute. That all changed when I moved to Martinsville Virgiane, Home to the Half Mile of Mayhem and NASCAR talent everywhere

So you have the front set up finished and are working on a rear?

Basically (for a simpleton like me) 4 drop spindles (knuckles)? Obviously the engineering behind it is being mildly insulted by me using a chassis design from the 60's but that is so I can visualize it for now.

Waiting for some pics and pricing.

Sounds great man. Coming back strong. I'm happy for you...

The engineering is complete for the front and rear. We are working through tool pathing, again When is perfect really perfect? It must be now, because this is the last tool path Our race TEAMs will get the first production pieces in about three weeks.

Sounds killer man. So what is going to be the hot set up? These with the Z/28 package or are you still looking at coil overs? I've gotten the impression you are pleased with the Z/28 parts though.

Looking forward to what they do...

The need for the Knuckle Drop is driven by the excellence coming out of Detroit in suspension design and execution. GM is putting MRC to great use in a wide range of vehicles. The best way to improve the performance of a MRC vehicle is to lower it with a Knuckle Drop. Suspension geometry and travel are maintained. Ride quality is maintained. MRC function is maintained. The Center of Gravity is lowered. Handling improves.

The Z/28 Multimatic DSSV struts are off the charts good. The Racers we are working with swear by the Z/28, but want it lowered with a Knuckle Drop for all the same reasons.

There is a coilover company we are working with to package a Knuckle Drop Coilover solution that looks very promising too.

Improved suspension is a trend you can see and experience across brands and models. The low hanging fruit is gone. The OE parts bins are deep. The best solutions for imporved handling and performance will be hybrids that take the best out of the OE parts bin and engineer parts around them.
