On lowering the car. We were working on this when I blew it up. How much can you lower while maintaining suspension geometry? I set the height by sight and then checked the geometry and it was surprisingly close to having the front lower control arms parallel with the ground. This was with Dunlop 235 60. I am pretty sure the Avons are going to have them exactly parallel if we make no other changes because of the increase in the diameter of the tire.

When you lower them do you run the stock suspension and steering components?

How much can you lower without inducing bump steer, running out of shock, etc.? Anythings special to look out for here?

I am not building a race car. I will still run it on the street, but I would like it to handle the best we can get it without re-invent of the the wheel. That said - track performance is of higher priority than street manners. Once I get tired of throwing money down the drain we can de-tune it, bolt the windshield on, put the carpet back in, and take it to Sunday breakfast.

G-7 Slicks - 15" rim? Not familiar.
