CR-1 seem stiff enough, for me anyway... Seem stiffer vs. A052, but it's been a year and a half and I only ran those tires on the Cayman.

I liked the feedback I got from the CR-1s and they were imo pretty tenacious, I could really drag the car down to the apex.

Just received my 255 CR-1's.
My old 255 Yok A052's are measuring 10" total width mounted on a 9" wide wheel.
The un-mounted 255 CR-1's are measuring 10.25" total width.

I'll report back with mounted width in a couple days.

That's alot of meat. You boosted or NA?

NA. Just a header and tune. Car is setup for autocross in STX class, so not much power, all about the cornering grip.

255/40R17 CR-1's on 17x9" +40mm wheel.

Just went out and did a little scrubbing. No issues with rubbing that I didn't already have with my 255 A052s (inside front at full lock)

Thanks, Breezio!

I've got mine on order now :)

BTW. First event on the CR-1's went great. Got to try them in wet and dry, performed well both times. Very similar to Yok's.
On the second day, scrubbed in and a good heat cycle, pulled 3rd Pax and 8th Raw (second fastest car not on Hoosiers) out of 60 drivers.

Second event is this weekend. Should be dry and hot. I'm excited.
