I note the 888s seem to be popular on this forum. Where does this come from?

In my experience they are a good (track) tyre but there are better. They do wear really well though, so if you are driving to and from the track they are a good choice.

[Pparana]

Agree there are much better, but people do seem to like them. I think it's a little dated and there are better extreme performance and r comp tires for less money.

They're good and sticky, but it depends on what you want. I'm a lazy bastard, and just use the same tires for everything, so I stick to things that have a 200 TW minimum (personal favorite are the Dunlop Direzzas).

I think Pparana is right, they are good, but tire tech has advanced and there are just better, more durable things out there. I've heard great things about the RE-71's, except that the 200 TW rating is just Bridgestone's opinion, man. Apparently they don't last very long.

my R888s worked well for autox until and for one track day

after the track day (at Chuckwalla), they were useless for autox

plenty of tread left, they just "cycled out"

I'm going to RE-71Rs for autox and just use my PSSes for the track

I have Kosei K4R wheels with et42, and I was wondering if anyone has tried mounting Toyo RA-1 in the 255/40/17 size for track use and, if so, is there any rubbing?

I currently run Hankook RS-3 in 245/40/17 (square set-up) without any issues, but I'm looking for more grip.

Not more grip in terms of contact patch but in terms of rubber and, to a lesser degree, sidewall stiffness - they don't make RA-1 in 245.

If you know of a better R-compound that you can drive to the track, and then some, let me know.

Unless you have some increased camber in front, you won't be able to run any 255 section width tire in the front. I don't know if the LCA's alone will work (I don't use them, just have camber plates), but you will need more than stock camber to run a 255 square setup.

LCAs alone actually hurt, they decrease tire->fender clearance

Yokohama A050s are the best semi slick around imo. I have tried many, not on the beemer. Sticky, quick and wear really well. I thought the 888 thing might be specific to BMWs due to the weight/alignment or something.

Durrizzas are the best all rounder. By far, re 71 are the loudest tire I have ever heard., I would defiantly take durrizzas if I was not running slicks or only had one set of wheels, But slicks are like crack and you will never go back.

I like the hanooks, they last and are predictable, an experienced driver can get more out of durrizzas though.

That's what I've heard but I think they might only be available in Japan and Australia.

That is unfortunate for the north Americans. Fortunate for us though!

Then the question is, can 255 be run on the rear with 17 X 8.5 et42 on the rear without increased camber ??

Should work. I am running 18x8.5 ET 38 with 255s and -2.0 camber. It pokes just a little bit but I haven't gotten any rub, even with H&R springs.

You should be fine with 4mm less poke. By the way, you do know you can adjust camber on the rear without any aftermarket parts, right?

yep

I know, but since I only mount my Kosei/Toyo RA-1 for the track I would like to keep the camber stock, so as not to use up the insides of my PSS too fast.

BTW, the 17 X 8.5 have an et40 and not 42 (my bad).
