Couple weeks ago I did a 2 day event at NJMP with a new set of SS. Back to back 25 minute sessions at a time (my brother was also driving my car). The tires looked very good afterwards with no signs of cording. Also they didn't get anywhere near too greasy after these extended runs. Weather was only in low 60s though.

I plan to rotate lefts and rights every event this season. Seems to me like cheap, easy way to extend the tires life, at least on the outsides. (Last year, pre track/street alignment, at Monticello open track day I corded a set of SS on the left side only -- right side looked fine).

I've also been working on trail braking every turn and I can feel the car understeer less and thus less strain on the tires. I think driving style is a big factor that gets overlooked in discussion on specs, equipment, etc.

Separately, I have to say the Pagids are a huge huge upgrade if you are spending significant time at the track. The braking power and consistency really added to my enjoyment and sense of security. Can be loud on the street (much less so after a good torching at the track) but very easy to swap in and out on a 997.1. Probably saves money too when all is said and done. I didn't believe how easy the swap was until a kind forum member showed me in person but seriously, we're talking a couple minutes a caliper with the wheel off.

Mike -- hope to see you at Metro NJMP in a couple weeks. All the best in the meanwhile and enjoy the new harnesses and seats -- I'm very jealous!
lee,

trail braking will keep the front loaded and you will have less understeer. Not sure I would do it at every turn at NJMP but I dont think you mean that.

I'll catch up with you at metro...i like the idea of 2 days on lightening. I really dont have that track down and it will be good to work on it.

I suppose the harder compound on the SS's vs. PS2's could account for their pressure sensitivity. Your camber appears well-balanced front to rear but as you point out is quite aggressive - perhaps even very aggressive for a street setup unless replacing tires frequently is not a big deal. It should help with the outside cording issue on the track, all other things being equal but will put a lot of strain on the insides on the street. You couldn't hit those specs without the LCA's. What did they do on the toe settings? I don't know much about toe settings although I'm coming to believe this is where alignments really get fine tuned and tweaked. It will be interesting to see how fast you go though this set of tires with the new alignment. Best,
SB,

I need to check the alignment sheets for the toe...don't have them at the movement. Bodymotion has done all the work on the car since I got it and they recommend the agressive camber.

I am also interested in how long they last.

best
