[Fot] so I have these 2 cars...

[Jack Wheeler]

 Back in the early 80's, I built a TR-3 race car on a TR-4A frame.  IRS was not legal on a TR-3 in SCCA at that time, but I planned to use coil overs in the rear, so that wasn't an issue.  I remember I had to narrow the frame by cutting off about 4" at the "corners" where it sticks out just before the section where the trailing arms would attach on an IRS car.  I welded a plate over the hole in the frame left where I had cut it off.  Ironically, the widest part of the TR-4A frame occurred at the narrowest part of the TR-3 body.  Otherwise, everything else worked fine.  I used wide fiberglass fenders, which I got from John Holsonback.  His car popped up recently by someone on the FOT list.  It was a red TR-3 from Wichita, KS.  I sold the car the following year and went back to my trusty TR-4, which was a better handling car.  My lap times with the TR-3 at Atlanta were about a second slower than my TR-4 the year before, with the same drive train.  I attributed the difference to handling.

 These 2 cars have been sittin in the back of the shop long enuf. One is a solid TR3A and the other a late TR4A in lesser condition. So I'm thinkin that a frame off needs to be done on the 3 and as it sits next to the 4A, I got to thinkin (always trouble). The 3 was to be a replacement for a really worn out TR3 racer and I started transforming the car to race specs. Gee that was about 30 years ago! Somehow I got sidetracked and raced other cars, and the 3 just collected dust. So...how bout an irs TR3? I've got flaired fenders from the old racer, so the wider frame won't be an issue...BUT, has anyone else done this? What sort of issues are in store here? This won't be a racer, but rather a hotrod street car, so anything goes.
Thoughts?
