I'm putting my 1962 A-H Sprite MK2 back together following fresh paint. I've decided to paint it every 9 or 10 years on general principle. Anyway, it has a pretty stong 1275 engine, and all the rest was comprehensively rebuilt during a down-to-the-last-fastener resto job 10 years and 8000 miles ago. The suspension is the ancient race springs that were on the car when I got it, a 1/2" front 'bar, rear panhard bar, and shortly, some eccentric front bushings to induce a little negative camber in.
Rims are 13 x 5" copies of copies of Minilites. Fender arches are stock front and rear, and ride height is pretty low, so the 165/70-13 Michelin Rainforce all-seasons on the car now don't have a ton of room to spare.
As a diversion from the merciless ass-kicking I receive attempting to "compete" in STU class in an e36 M3, I'd like to autocross the Sprite with the local "fun autocross series", and toward that end need some decent rubber.
Not a lot exists in sub 185 R comps. I can get formula 2000 slicks cheap, but the club doesn't allow non-DOT rubber.
Tar' 'Rack has THESE
In which case the 175 would be offset by the 50 aspect ratio.
Hoosier TDs and a gazillion arcane Avons are available, but for a 1350 pound relatively low HP car, there must be ~aomething~ that doesn't cost $800 a set.
What say y'all fans of cars with tiny wheels? any ideas I haven't seen while obsessively researching this?
