get the 255s. they're in stock.

 

My 245's arent dead yet. I was more referring to when these wear out, if the 255 RS3's are backordered everywhere again. Im planning on burning up the rest of the 245's over the winter (all year autox in florida)

 

Bryan, you should be able to find some 255's. Even 2 weeks before nationals when everyone was clamoring about how they were unavailable I found some.

So if you were faster on the 255 hankooks...just get another set. If you really can't find them, I can't imagine the 245 is much if any slower. Me personally I'm going to do some dunlop vs hankook testing because at nats both me and Tory were much faster on dunlops for some reason (at least on the test and tune course where I tested back to back).

 

R-S3s or Star Specs are in stock? How do you know?

 

Glagola also found the same to be true on the test course.

I speculate that there is little difference in the ultimate pace of the tires, but I feel compelled to think the RS3, in the right temperatue zone is going to generate the most grip. I have no datalogging to back this up, but would relish the opportunity. The operating temps of each tire are the big differentiator. The toyos love to be ambient, the hankooks need more heat than a hoosier A6 to work at their peak. The Dunlops seem to be in the middle from my experience. When I ran Dunlops on my B-stock ap1, they would definitely fall off with large amounts of heat. So it's a pick your poison kind of thing. The feel and feedback is where the tires differ greatly. Matt said he really liked the feel of the dunlops. I like the feel also, it's more like a conventional street tire with a lot of "vibration" at the limit. The RS-3 has r-comp feel, all grip then a quick drop off and much less vibration. Though with the RS-3's, you'll likely get 3 really good cracks at the course with a codriven car. The Dunlops will likely need more attention with a sprayer, still more with the Toyo's, which in my personal experience, are fastest with almost no heat. This is why the light cars (NA/NB Miatas, even NC's)love them.

Tried 245s just before nationals and immediately sold them and found some used 255 R-S3s. The 255s had one event on them and were over a year old.

I found the 245 grip to be significantly less than the 255s and that they heated up way too fast, before the run was done. After the second run they were heavily sprayed with water after each run.

I would choose the 255 Dunlops over the 245 R-S3s. 245s might be good to have in the cooler weather when you need to generate more heat in the tires.

Maybe the stiffer side wall of the Dunlop can be attributed for making more grip on the Lincoln concrete. They always feel good, but maybe that surface allowed them to make better grip. We ran more compression on all corners at Lincoln and it worked great (R-S3s). Maybe there's a relationship here between the stiffer sidewall and more compression force? Are they similar in affect in this case?

Good description of the tires Nick, I agree.

 

Photos?

 

Ill grab some tomorrow and a video.

 

Rs3. I just ordered some. Showed up today.
