I'm curious about how well the wheels fit in the back, what the alignment specs are, and if you had to make any compromises on the alignment to fit the wheels?? I'm wondering because I would have guessed that the +35 offset would have fit better than the +45 (at least on the back).... Again, just a guess.

Follow up did you think about adding a roll bar or harness bar to rear?

I want one. As soon as someone make one for our car, I will be on it.

When you say "well" what do you mean? Aesthetics or functionality? I run 275 all around without any rubbing. Did not have to cut fender, so I would say it fits well. No compromises on alignment. I run zero toe in front. Stock toe in the rear. -2 camber in the front and -3 in the rear

You'll be waiting a long time for someone to make one. These cars are not used in any racing series in quantity, so real racing parts will be custom or non-extant.

Harness bars are a really bad idea. A harness without a rollbar is asking to be crushed.

Thanks for the reply, I meant functionally, so no rubbing sounds good to me!

Agreed. I will have to have it custom made.

A few ISFs run in one of the smaller endurance racing championships, they do exist but I assume parts will still be very expensive.

What was your strategy on your camber settings? Are you taking hot tire temps? I'm used to running a more aggressive front camber than rear in a RWD car to create a little rotation, better power out of turns and remove some understeer. Maybe the ISF tends to oversteer at the limit with a square set-up. Just wondering.

That works nicely for a harness bar and rollover protection. Still streetable too - unlike a full cage where you are foolish at best if you don't wear your helmet. There's enough room that you won't be smacking your head on it except in the most dire of circumstances.

Less undesteer with a square setup. Right now the car is neutral. Camber settings were just a starting point. I will play with it more after I install my Penskes. I have a pyrometer but I have not taken temps yet.
