Wow - that looks low. Have you measured your chassis height yet - just out of curiosity? Also it looks stunning. Nice find.

Knowing what I know now - I could probably have had Vintage reduce the backspace on my wheels by a 1/4 inch or so, to push the lesser-width tire closer to the fender edge and increase room for the pipes. However, mine seems to work fine and I haven't had any contact between the pipes and tires. I did wrap the pipes in the vicinity of the tire with header wrap as a precaution.

Going with oval tubing in the wheel well is also another possibility. And finally, I'm not sure 2-1/2 inch tailpipes are absolutely necessary. The exhaust temps past the muffler should be cooling down slightly which would allow the gases to shrink in volume some, allowing a smaller tail pipe. But the 2-1/2 inch pipes do look and sound mean.

Original SC cars apparently ran 9.00-15 tires on the rear but I haven't been able to find actual dimensions for them. Some cross-reference tables suggested a 265/60-15 or 255/70-15 would approximate them - but I'm suspicious of the accuracy of some of these cross-reference tables. Either of those would be a fairly tall tire - probably around 28 inches - and I don't think that will fit unless the earlier generation ERAs had a little more wheel well room. The tight point on my car is the forward wheel well panel just behind the seat.
