Bonus points: Who makes the cheapest 18x10 40mm offset wheel that I can trust in an endurance race?
Don't have any lap time data on 275 vs 255 on an FT86, but I didn't lose much if anything in terms of lap times going from 245/40-17 on 17x9 to 225/45-17 on 17x9...

I would not bet against 255/35-18 on 18x10 being quicker around some, (maybe most) tracks vs. taller and heavier and draggier 275/35-18 on the same wheel!

If you get a weight break with the 255s, no question, I'd go that route for sure.

Also, as an aside, anyone have any idea what my car will roughly dyno (I'm asking because I need to adjust weight)
93 Tune, EL headers, intake, intake manifold riser, catback, lightweight flywheel
180? 185?
Depends a lot on buncha factors. Could be anywhere from maybe 165 to 185 max?
