I don't like to refer to EvoM much, but in the TireRack tire/suspension section, you'll see that the first recommendation for replacing the Advans is ALWAYS the 255 RT615s. People even run 17X9s with 255s without rubbing, but you did say aggressive alignment, and I only have stock suspension pushed out to -2.0 camber up front, so it's not as aggressive as you probably.
Yeah I have only done research independent of the evo sites, but with it working for everyone and times getting faster it seems more and more that it may not be the problem I was thinking it would be. Though this all might be a lost cause as I really want to do 17x9s with coilovers and I doubt Im gonna be able to hold out thorugh another set of tires before I do the switch over.
I'm doing 17X9 (or 9.5) RPF-1s with 275/40-17 V710s during the offseason. Actually, it may come sooner, since my 245/45 V710s just corded yesterday. That wheel/tire setup will be combined with some Ohlins for what will hopefully be a very competitive season for me next year in both SM and TTU.
For more details on my RT615s, our last NASA event at La Junta, I had them on and outran everyone in my class, which included 3 modded Z06s all on race tires. My brakes disintegrated at the end of session 2 (out of 8), and at the time, I was fastest lap of any class, but by the end of day 2, I was 4th overall. 2 race cars had passed me (AI Camaro and World Speed Challenge SRT-4) along with one of the Z06s in my class who nipped me by .2. My distance from the fastest lap (SRT-4) was only 1.2s, so the RT615s were really perrforming.
Then, I went to PMI in Pueblo for an open track day and ran several seconds faster than anyone, including one heavily modded Evo with suspension and larger turbo. And of course, yesterday at PMI again, I ran a 1:46.9 on the RT615s when there were only 2 of us below 1:50...
All right so its official. SCC magazine is stating that the 255/40 is a good and safe track tire size for the evos stock wheels. That was the final nail in the coffin. My next set of tires are gonna be the azenis in the 255/40's.
