C4 Corvette IRS in 55-59

[Houston54]

The brake size issue is known and I plan to run 16 or 17 inchers. That is the main purpose of the thread though. I have seen the threads on Porterhouse's outstanding work but in my ap I am not tubbing/backhalfing or making mods to the fenders. I did not see anything in those threads that address my concerns regarding back spacing, width and diameter.

I read that some 16s work fine and others do not with this. I talked with Don at Flat Out Engineering and he was of the opinion that was only with the C4 "front" suspension.

The 58 will have a Fatman IFS kit on the front with standard 10.5 rotors at least to start. I am not that thrilled with showing off the brakes and like the look of the steel gennie rims. I am just not a fan of Wheel Vintiques as their caps seem to crappy and I have read of run-out problems with their rims. That issue can be resolved later though.

I mainly want to find out what other wheel/tire combos have been used by others with a similar project plan. There may not be any out there in which case I will find the answers through trial and error.

Thanks for comments though and I am glad to hear from a C4 owner that they love the handling performance.

The kit I am planning to use does away with the stock spring in place of coil overs. I might investigate retaining the spring or replacing it with a light weight unit if one exists.
