Difference between c5 and c6 corvette suspension

[XLexusTech]

So the cradle is interchangeable... that interesting.. is that the preferred way to go with an LS swap I wonder ?

The C5's are pretty darn in expensive..

I’m not sure what you mean as the C5 and C6 already have an LS?

Ok guess c4 is what I was thinking then

There is some misinformation above... some parts will bolt in place of others, but they do not swap directly.

The upper rear control arms are DIFFERENT GEOMETRICALLY between a c5 and c6... the ball joint hole is further back on one of them. (The C6 I believe.)

The rear cradles are DIFFERENT due to the transmission mount and springs.

Z06 Upper rear control arms are a special breed as well.

The C6/C5 rear LCAs as the same geometrically, however NOT interchangeable due to spring mount differences. (unless you use coilovers... then they are a direct swap.)

On the fronts, I believe the steering rack mounts a bit differently relative to the lower control arms resulting in different bump steer characteristics... but I cannot personally confirm that.

The lower have to be different geometry or the wheel wouldn't move depending on running a C5 or a C6 control arm.

Ive compared c5 c6 uppers side by side... they are different t. The lowers are the same except the spring mount.. The cradle on a c6 is mounted further back to accompliah moving the wheel backward.

That doesn't make much sense that the wheels don't move when swapping the C6 cradle into a C5 and not the control arms, but they do when swapping the cradle and control arms though?

Oh trust me, parting out a wrecked C5/6 would be a great way to swap everything into an older car. The problem presents itself with mounting the subframes (if you want a true "bold on" affair). You'll need a LOT of fab in order for everything to bolt up. But its a tried and true way to go fast!

My initial measurements from come corvette racers are saying that non-aggressive c5/6 wheel fitments should fit under an F-body but I've yet to actually check/confirm.

I spent a LOT of time working with C5's and I'd honestly love to take my 2nd gen and use c6 suspension on it. With all of that, and if you look at nickcornilsen's posts, you'll need to lengthen the torque tubes for most classics. But the ability to buy cheap/strong parts that are based off a pretty damn good geometry is intriguing.
