Hi.

[t walgamuth]

Nothing much done this week or last. I had cataract surgery last wed. and will do the other eye today. Lots of thinking.

In my receipts from the PO there is a receipt for raising the car 1" on its suspension "to improve streetability" or some such. The truth, I believe, is that it was raised to keep it off the tires because they stick out too far. So I am looking for wheels with more backspacing so I can lower the car and the tires will tuck up inside the fender like they should.

The problem is finding wheels that fit 5 on 5" bolt patterns that will carry the tires and not be too heavy. I found some lovely wheels but they are for 5 on 4.75" bolt patterns.

I may have the studs relocated in the hub to fit the 5 on 4.75" pattern that is common with Corvettes of certain years and look to have backsets which will be an improvment to what I have.

I also noted that the lower a arms on front are not parallel to the ground. I believe I'll have to relocate the front down so they will be parallel.

The rear I am trying to figure out but I think lowering it will settle the car too.

Why do they "need" to be parallel?

They may be closer to parallel to the ground when you lower it after the wheel swap.

Exactly.

American Racing has a Custom Shop and their VN407 wheel is designed for Cobras - though not faithful to the Halibrand design: Our Custom Shop is a state of the art custom wheel building facility located in Southern California. We have all the capabilities to practically build any custom wheel you can dream up. Custom forged, specialty two-piece fitments, unique finishes and colors, drill-from-blank services.http://www.americanracing.com/customShop.cfm


Vintage Wheels has a variety of bolt-on and pin-drive wheels to fit 5 x 5.0" bolt circle, and they'll make them with custom offsets, and it seems they offer the AR wheels above, along with others. Vintage Wheels, Mustang, Hot Rod and Muscle Car


As to whether your control arms are parallel to the ground, as soon as you're in compression or rebound that's all going to change anyway. For autocross and other track use I'd focus on ride height and corner balancing as a higher priority than control arm parallelism. Don't forget to get a full alignment once you've set the ride height and corner-balanced the car.

Thanks Brian! I'll check out those two sites. I corner weighed the car first thing. It is very close to a perfect 50/50 weight distribution.
