We had seen several C4 cobras but we thought we would try to top them with a C5/C6, the trans axle offers an obvious advantage as well as the rear wishbone setup over the 4 bar.
Side note: We just got our first LS7 yesterday, fresh in the crate, I would love to put that in there but then I would have a 57 convertible short a motor and I would have a Cobra with a “427 Side Oiler” LS7 and enough horse power to scare the crap of pro-drivers.
We are still waiting on parts to get back on the cobra but for the guys who have the C4 stuff we made this plate that would let you put the C5 or C6 (including those 6 pistons corvette brakes) and just blot them on this is our 32 we are finishing out the chassis and it will be on the road ASAP. You can see the plates on the passenger side rotor, just bolts on and everything lines up perfectly, cheapest brake up grades on the market for the corvette suspensions.
The only thing I would change on the C4 setup you have is the plate the stock shock mounts to. It’s a thin piece of aluminum not designed to support the weight of the car 100% of the time. We build a heaver pair of brackets to offer a little less flex, you can see them in there as well. And move the shock below the A arm to avoid any adjustment interference. Plus, I like the way it looks better on an open wheeled car. The aluminum plate is only seen on the 84-87 corvette suspension, if memory serves, the later ones, 88-96, have a modified lower A arm to fit the shock to it.
