what are the optimum 15" wheel specs?

Wow thats light! Mine are 12.5 lbs. and old. But Konigs are way cheaper unless you can get used.

My DGF has these on her Civic and destroyed 3 of them on potholes. Which is why I recommended the Team Dynamics, used on Spec Miata, about 30 bucks more per wheel, much tougher than Konigs or similar designs. They pay for themselves, while at the weight limit of what our 2s can handle, 13 plus pounds per wheel.

what about offset?

8's 25-32 ? (may be issue lowered)
7.5's 30-32
7's. 38-40
6.5's 38-42.

Optimal offsets.

Brian at Goodwin Racing (forum sponsor) can get you the details. I've had one set on the Miata for 5 years of HPDEs, Autocross and DD on the same roads that keep destroying the lesser wheels. BTW I did buy replacements from the same place. Nice thing about Konigs is that I got about 15 bucks from the local scrapyard.
