I flipped my quad shocks with the excellent 315 Sumitomos because there was about 1/16" clearance...I have 1.5" drop on Eibach springs.
I happen to LIKE the Sumitomos that everyone runs down...I have 25,000 miles on them in 8 years now & they will easily hit 30k+...they had good traction the first few years but definitely have hardened up & spin easily now...which I like with my stock 2:73's lol, they did good in the wet at first which I rarely saw but I DO live in Oregon. I only drive about 3000 miles a year going to shows & cruising etc. and make a big effort to avoid the wet times as I would with any Z rated summer only tire. I especially take care now that the tires are older & less tread...sure hard to beat the price of the Sumi's!
