Default LS 84 Z28 Corvette suspension





I’ve just begun driving this, it took about a decade to get to this point. I’m starting the body mods this winter.

Awesome! Beautiful car. Manual or auto?

I bet it's a hoot!

I forgot to include the transmission and exhaust in the description. I have a T56 with the common durability upgrades with an RTX dual disk clutch, Tick hydraulics, and B&M shifter. The exhaust is dual 3”, X crossover, with 2 MagnaFlow “mufflers”. I took my son for a ride and he said “This thing is a riot”, not sure if he was referring to the acceleration or the exhaust.

Any possibilities of getting specs on the "custom front K member"? I have a 92 RS that could use one of these.

Installing a Corvette SLA front suspension on a 3rd gen Camaro is a big commitment. The frame rails have to be sectioned and altered 13*, and the inner fenders opened up before fabricating a K-member. If you are still interested in doing this I have a CAD drawing of the Corvette dimensions and can help with any questions you have. If what you want is just a tubular K-member, then any of the available units from various manufacturers would be easier and far more economical way to go. PM me with your email address if you want the CAD drawing.

Reinforcing the grill area

Preparing to remove the license plate mount

Sliced the lower spoiler level with the ground

The headlight support is bonded to the front bumper

Spoiler is much more aggressive

Fiberglass work is almost complete. Time to move on to metal work.

Look at you go! I really like what you have there. I am a big fan of thinking outside of the box. I am definitely going to follow this build.

I wanted something extraordinary and unique for my build and this is what I came up with.

Bead rolled and shrank the pans

Added side extensions

Fitted to the hood

After about 12 hours of tig welding

The hood is ready for primer, body work, and paint.

Pretty cool. Another guy over on Thirdgen.org also did a C4 front to do away with the modified macpherson strut suspension. He caught a lot of hell about it, the usual types "buy a vette", "the stock suspension works fine". I very much appreciate the desire to experiment and push boundaries.

I'm curious about the rear, what did you anchor the upper coil over mounts to? Did it interfere with the fuel tank? If the upper mount is in the stock location, does the coil width limit how much negative camber you can add (without interference from the upper arm/rod end bolt)? I also notice you have the lower trailing arms mounted to the stock shock mounts on the knuckles. Did you do that to get a decent location for the instant center and swing arm length without going too deep in to the rear seat area? The sway bar, and mounting are pretty interesting also, I noticed you flipped the toe rods so they mount underneath, to gain more compression clearance?

Where to start? If you are referring to the Bronze Firebird, he reached out to me after seeing what I had done and we spent several months talking it through over the phone. He started with a finished car and was able to drive his before I did. The rear frame arch was reinforced with a 3/16" plate that was formed to the arch and welded in to provide a mounting location for the differential and the coil overs, overall the frame is over a 1/4" thick in that area and the upper mount is roughly in the same location as the original shock mount. The fuel tank is from a 2000 Camaro SS that was a bolt in replacement for the stock tank, I left the inner steel structure that encloses the tank on both sides. The rear lower control arm brackets have been modified to give me more adjustment for anti-squat and IC (the upper control arms also have 3 adjustable positions) and the forward is mounted in the original Camaro location. The new brackets also reinforce the aluminum knuckles to better support the coil overs. The anti-sway bar end links were mounted this way in order to achieve the desired ride height without contacting the frame. It should also be noted that the rear wheel wells were tubbed 1 1/2" o n the inside so that I could run a 335 tire. I added a small cross member in the driveshaft tunnel for urethane forward differential mount. That's a lot to take in, and that was just the rear suspension. There was a lot of engineering that went into the front as well.
