RPF1 14x7 Street Performance Tires
I've been lurking on several forums for a while now. Even though I've seen many discussions on this topic, I'd appreciate MT opinions on all five tires which seem to meet the criteria for street performance with 14 inch rims. I know there are many more choices with 15s, but I'm sticking with my 14x7 28mm RPF1s. Shaikh tuned the FCMs to the light unsprung weight with 425/300 coilovers, and I love the feel. Tried my old Daisys with Sumitomo All Season 185/60 14 this winter, and the ride sucks. Only a few pounds more, but bumps feel like sledgehammers to me.
Problem, of course, is performance tire choices. I know I could switch to 15s, but I want the 14s. Here is how I see the choices, and I'd appreciate input. 92 NA is a daily driver. Once a month I go for "spirited" (read "aggressive") runs with a group of fast drivers. Track days 4-5 times a year. Not worried about noise, ride quality, or tire wear.
Direzza ZII, 185/60. Stretched a lot on 7" rims. The lightest possible combination, but it just doesn't look right to me. Will ignore the look if it works the best. Function>Form
Falken 615k, 195/60. Wider, not so stretched. However, looks too tall to me. Diameter more than stock, might be less "lively" feel than lighter smaller ZII.
Nitto NT01, 205/55. Best look as far as size goes. Diameter is same as stock. Light weight. Great stickiness, obviously with R compound. Not so great in rain, maybe. High wear? Heat cycle?
Toyo R888 205/55. Similar to NT01 in many ways. Same advantages, same problems?
Toyo R888 225/50. Meaty. Wide. Maybe too wide for 7" rim. Should be crazy sticky, though. Prone to chunking in heat? Will it work OK on track, or is it just too wide?
Any other ideas? Summer's coming and I want to be ready for the next run!
