I had Toyo r888r's all around on my stock wheels and recently purchased a set of new wheels from Signature; 19's all around. Went with r888r's again all around, this time with a 345 in the rear vs. a 325 on the stock.
My car puts down 1,000 whp and they hook pretty good from a roll. I've never ran them 1/4, I have a drag pack with MT's for the track.
Overall I'm very happy with them (on my 2nd set). They can be a little noisey but I don't mind it at all.
