Here's what my tires (Toyo Proxes) looked like after Sunday's DE @ Thunderhill. This is also after the 100+ mile drive home, which "cleaned" them a little.

 

I've been running Mich MXX3's on my stock 944 at DE's. No blistering or chunking yet, even though they chirp alot in threshold breaking and skreetch through all the turns. They also gain a nice consistent 5-7 psi all the way around (40 psi hot). 'Course they're being phased out. I hear the Pilot SX replacements have a bit more silica (read less dry grip) and will have a wider slip angle (more forgiving) as a result.

What are you running the Toyos on?

 

Thom-
Which Proxes are those, they RA1s? Are you saying that all the mileage you have on them is the one DE and the trip home? They look pretty shagged if so.
What did you think about them on the track?
I've been considering these tires myself.
Thanks

Chris,

Thom will have to tell you which Toyo Proxes those are, as they don't look like any on their web site. The RA1's are shown under tires, high performance on the www.toyo.com web site.

 

Relax guys - I got these tires used when I bought the wheels. They had good tread on them, but I'm guessing they were at least 2 years old.

FWIW, they handled great on the track.

 

that's an interesting wear pattern...mind if I ask how much camber you're running? I'm running factory spec camber (about 0.5) and get tons of wear on the outside of the tire at the track. Your wear is all on the inside. I'd like to strike a more even middle ground... Some folks have run 2.0 degrees with success but I'd love to hear what your spec is.

 

Keep in mind that I got these tires used, so the wear pattern was already well-established.

With that being said, I'm running 1.5 degrees negative camber, and have a strut tower brace that's preloaded a wee bit to the negative side as well. I'm running 2 degrees negative in the rear. I eat tires, but it's a lot of fun to drive!

 

Also keep in mind that Thunderhill is a counterclockwise track, and you're taking a lot more left turns than right. My 95 993 rear right tire's outside edge gets so munched at Thunderhill, that last time I was there, I switched my rears, to even out the wear.

I forgot what my suspension is set at, but it's slightly more aggressive than factory setting.

Tires where SO-2 Pole Positions, 17". What a piece of $%#@! Never again. Next tire will be P-Zero Asymmetricos...

 

They are not RA1s - or if they are, they must be an older version. I just got a set and the tread pattern is quite different. Taking them to their first DE event this weekend.
