Great thread, great knowledge, great skills and great to follow thanks for posting - what is it with a rack and throwing out the geometry?

Because of the position that a rack fits in it changes the angle of the steering tie rods in relation to the wishbones and can cause a significant increase in bump steer. The C3 has a less than optimal setup for bump steer to start off with and a rack can make it worse.

Cheers that is what I thought, some rack sets now come with the track rod ends with longer bolts (studs) and spacers to facilitate adjusting the angle of the tie rods
I had had a recent body off including installation of a steering rack and the Vette went to another but this time (so called Vette specialist) for some odd jobs, all of which, he either screwed up or failed to do and one of his cons was: "I know it is all new but one of your track rod ends was faulty, so I replaced it," he then showed me the one he allegedly had taken off, I Knew it was not mine because of the length of the bolt was short as per normal set up - I looked at him and smiled.
Your blessed you have the knowledge and capability to do it all yourself
You are certainly not lacking in your ability and for a new owner you certainly know your way around a C3
If I may ask, what is your back ground that has given you the understanding of what you are doing, engineering or just good "hands on" experience and in depth knowledge gained from preparing race cars ?
Great Thread thank you.

I’m a civil engineer on the railways so I don’t think that counts.
Basically just 25 years of building and maintaining cars. My Dad taught me a lot as did an old boss who was British Autocross Champion in the 70s. Basically if you can bugger it up on a car I probably have!
Bodywork is the one thing I really don’t think I’m good at. Not happy with this at the moment.

Thanks Keith
really interesting read, what spring rate are you having on the front end unless I missed it I think you said you were going with a 400lb rear spring. Will it be composite or is that not allowed also?

I used to have 550lb coils on the front of my BB which lowerered the ride height by about 40mm which was too low for the street, 1 1/8” ARB, and 360lb rear spring, and bilstein gas shocks all round all from VB&P. Would that be too heavy for the front end with a SB you plan to use?

Why do you need the hole for access?

Far easier to get the diff off quickly from above than undoing the crossmember and fiddling to get that and the diff out. A lot of people also weld the crossmember in place but I’m just solid mounting it

Didn’t think you would lose that much weight from the strip down. Especially when you have all that extra metal from the rollcage?

You’d be amazed how much weight there is in some things, like seats and window winder mech, no bumpers or spare wheel, all the headlight and vacuum stuff etc.

Pretty much. Haven’t completely decided on the dash but the only bit of Vette you’re likely to see will be the dash top. Everything else is gone.
