But you haven't tried the Falkens?
I’ve got the 660s on the cayman. And I’ve driven on them on a TypeR. Better laterally then a RE71r. Run big!

Slightly softer sidewall then the 71s. And I got 265 71Rs to mount. So if you have a good guy - they should mount.

I took a set of 265 RT660s in when I had my 255 RE71Rs mounted and they are so much wider the tire guy looked at me and said no way. I'm sure with enough time and patience you could get them but will it even be worth it?
Good question. Also, is it worth the extra $300/set over what I'd pay for 245s? I'm beginning to doubt it's worth the trouble. The car was very competitive with 245s. (255s cost more than 265s up here.) Plus there is the question as to whether or not the extra 1-2cm actually buys you much additional grip given that the small rim causes the outer surface to slightly curve up.

Nice car and wheels, BTW.

truthfully 245s from most manufacturers seems to be a sweet spot with an 8" wide rim. Even with 255s I got a lot of sidewall flex with RE71s and if the RT660s are softer as most say I would be worried. I will probably mount a set of 255 RT660s though once the REs burn up so I can get as much surface as possible. Have to do everything we can to keep up with the CTRs.

I’ve been very pleased with my 255 660s. I run almost exclusively on old concrete and haven’t seen any roll-up on the sidewalls running 38#/34#. Wear has been really good.
I've been running 42 front, 38 rear. What height sidewall on your 255s? 35 or 40? The 255/35-18 drops height by 4mm or so.

Glad you guys brought up pressures as talking with locals who switched to the 660s they all seem to be running higher pressures than with the REs. On the surfaces we run around here I found low 30s (31-34 psi) to be the sweet spot for RE's. Are you all running higher pressures with the 660s vs REs?
