I have the 245s on my front, but the 305s did not fit on my rear. Over significant dips/bumps they would rub on the fender. How much camber do you have in the rear?

-2.0 to -2.5 I can't remember off the top of my head. I will check when I get home today and let you know. The rears do rub a little bit over significant bumps but it is nothing to worry about since Porsche gives the inside lip a smooth rolled edge. An easy fix would be to roll the inner fender lip a little bit more. Over normal track conditions the tire fits perfect. The only time I ever had an issue with mine was hopping curbs at Road Atlanta.

I just run RA1s 245F and 305R in 18" at Pocono on my 997S. This tires are GREAT!!
I also started using them on the Elise.
They appear to be the "magical" tire as it cna be driven on the street to the track and have very impressive grip, more than the Yoko 048s (which I used in the Elise for the last 18months).
Here is a video of a couple of laps of the 997S on RA1s:

glad you like it. i have been telling my friends that this is the tire to get.
of course after i told everyone, my size 275 35 18 are out of stock nationally for that last 3-4 months.

btw, if you liek RA1 try nitto n01, they are very similar. very very similar. secrete has it that they are the same manufacturer and same compound. they are cheaper than RA1 by a tad for my sizes. they are 6/32 while RA1 is 8/32.

cgomez, if you liek ra1 now, wait until you use up 1/2 the treads, THEN, the really stick. full tread tend to squirm a little.

mooty (aka Polar), I did my research . Shaved RA1s for me baby....
Both in the Elise and the 997S.

I still can't believe the difference they made in the Elise (1.5secs!). I guess a lot has to do that the extra grip just allows that marginal speed increase to be "on-cam" on corner exit more than before. Check this Elise Vids on RA1s:

yes, i am polar, i WAS mooty on e talk, but can't remember my passwords and since i suck with computers, i just reg'd again, LOL.

and if you run high camber and drive on street. the RA1 CAN be flipped on the rim, just dont drive in the wet (your tread will be reversed, obviously).

Seth Thomas

This is an Rcomp who needs tread.

mooty

you got that right.

They are to tall for our cars..ABS problems

No problems with them on my car. I have not had an ABS problem at all with the car.
