Anyone running corrected roll center and bump steer with 305 square setup? I figure for actual track work I'll probably buy a dedicated set of 6GR Ten Stain Bronze 19x11 ET50's with 20mm spacers up front and run some sticky track tires like the CUP2's from the PP2 or something similar.
I love the 4 square Pilot Sport 4S setup on my 23 lb RTR Tech 7's for street use. I dropped 48 lbs of rotating mass over the stock PP wheels / Pirellie tire setup and gained 4% final drive ratio, lower CG and better carcas response by running a 275/35R19 instead of 275/40R19's. Honestly I think 40 series is more of a performance luxury profile than a street performance or track tire profile.
But I'm also on full steeda front end links (High durometer tension links, extended ball stud lateral links and bump steer), so the geometry is correct for the lower ride height. I don't see many track guys mention if they have corrected geometry or not, but most of them are obviously lowered.
