Ok currently I'm running stock 18 size tires. Continental contisport contact p5. They do not grip at all from a dead stop. If I gas it too hard the back end wiggles and throttle gets cut. I'm getting dedicated summer wheels 19s. I'm looking for the best possible traction for straight line. No track use. I want the least limited wheel slip. I have stock lsd. I don't want an r compound either. Needs to work in the wet too. It's a daily vehicle. What are your opinions on best tires from what I'm wanting in a tire. Pss seem to have good reviews however Iv seen them compared to my current p5's and they are supposedly comparable?? The p5's suck for traction. depending on the tire id be looking at either a 265 or 275 rear. Thanks for the help guys.
The PSS tires start at 300TW (Treadwear) and go up from there. That is not what you want in either a high performance tire or a street/strip tire. The PSC tires start at 280TW and go down from there and by going down, means a softer tire. The lower the number, the softer the tire. The PSC (Sport Cup) tires are in a higher league performance wise than a PSS and are a great road tire, but to each tire is a trade off. You just have to find out what you can and can live without.

The 285 NT555 fit fine on my car without rubbing on the OE 18" 5-spokes. Lots of people here have run them. Not great fun in the wet though. To be honest, my 60' times were exactly the same on PSS.

That's interesting. 285's fit? That's a big tire. I am wondering then if the Nitto is hurt by the weight of the car. Some tires like the Toyo R888 are a good track tire for lighter cars under 3500lbs, but above that it really has issues. I am curious if the Nitto has the same issue.

Diabolis, do you have any experience with the RE-71R by any chance? I also did not like how the PSS behaved on track when hot, and am looking to replace this upcoming season with either the RE-11, RE-71R, or AD08R. I don't intend to drive like they will last beyond the summer. Thanks for your thoughts. 
The RE-71Rs do come in the OEM 18" and 19" C63 sizes and have a sufficient load rating for the car (95 F & 94 R), so it would be interesting to find out how they fare. I think they are the only tires with a relatively low treadwear rating (everything else is in the PSS category) that are not R-comps and will fit and support our cars. Would be interesting to try them on.

I've been toying with the idea of getting another set of custom forged rims and gettng 245F & 265R Pirelli Trofeo Rs for my existing 8.5" & 9.5" DPEs. I destroyed a set of Trofeo R fronts in no time, but that was with them mounted on the (narrow) OEM 18s... they did seem sticky enough though, and I'd love to try another set on a proper set of rims.

Good points Diabolis, thanks. I was going to try and fit 285/35-19 back there this year (with a little fender massaging), but my rim width is only 10" - borderline - so now you have me rethinking things.
Loved the R888's on my 996TT, but I've heard that they don't hold up well to the weight of our pigs.
Decisions decisions...

Sure they're loud, but are actually a very good value when it comes to R-comps. And, just try getting Hoosiers, BFGs, Victoracers, PSCs (actually - try finding any of them in a size and load rating that will hold up our C63s) or Trofeo Rs and see how much those will set you back. As for the car's weight, no tires are good for heavier cars. Actually, no *anything* is good for heavier cars except massive brake rotors to stop all that mass. 
I like the R888s better than the old RA1s. They have more initial grip than the RA1s, a stiffer sidewall, require less camber, don't squirm *nearly* as much when new (unshaved) and are not outright scary on the drive to & from the track. The only downside of the R888s that I can think of is that the RA1s would hold up until they were corded (essentially becoming slicks at 2/32s) whereas the R888s drop off once they get down to the wear bars. At least those were my impressions.

I've had one track day on the RE-71R's and I liked them much better than the PSS's. They had sharper turn in, better grip for exiting under power, and never got greasy. Next Friday I start a 3 day track event and I have a brand new set of RE-71R's installed just for this. If I get valid data from my track app (Harry's Lap Timer) I'll post any delta's and thoughts or impressions.

Clark Kent, how did you like those new RE-71R's on track? I'm actually leaning towards the PSC2's now but interested to hear how you got on.

i guess it depends on what u use the car for, personally, once i changed from the oem contis to pss, i couldnt be happier. for a daily driven car, it makes me feel safer in all weather conditions.
however, great advice was given by a forum member here previously, that was an actual tyre retailer, he said screw all the brand names and just buy a cheap crappy brand, i cant even remember what it was, but he raved about how great it was and how u can save so much money as it had similar performance for much less. i was sold
