How much faster are stiffer springs and revalved shocks?

Question for 996-GT3 owners. I have a set of almost new (3 race weekends) PSS10's w/700-900 Swift springs. They were revalved at the factory before shipping to match the new spring rates. The are Bilstein's 996 part number and I wondered if they would work on GT3's since we run with GT3 lower control arms. This was the spec for our 996 Spec series but we switched to JRZ 2-way RS's as they offered us an incredible deal. If they fit, they would be a great damper for a GT3 with these springs and valving. We paid $3,500 for the complete set...

Agreed.... I managed to shave 7-8 seconds from R888's too just broken in R6's, but my R888's were on their last legs LOL!

Their new radial slick. http://www.hoosiertire.com/speccat.pdf page 16
Amazing tire. Takes a few laps to get to temp but then they're heaven.
NJ-GT isn't selling his scud yet, and thats the one I'm getting.

Holy **** that's a great term for them LOLLL.... Dell, it was 98 degrees, like 70% tire left, the pressures got so high at VIR with that heat, it wore down the whole cnter of the tire within just a few hard laps.. I couldn't believe it, I was sliding around every single turn, being passed by EVERYONE including my buddy Stu on here who has a 997 GT3 who was filming it all.. Wasn't fun at all, switched to R6's with 2 heat cycles on them, and I was GONE!!!!

Holy mother are those some sticky tires. I drove on a set of them a couple weeks ago at Road Atlanta. Wow did they grip compared to an R-compound tire. They were on a BMW E46 M3 C-Mod racecar that I have driven several times in the past on Hoosier R6s. The best time I ever managed with the car was a 1:31.xxx with the R6s. Once I got some heat in the Hoosier slicks I was down into the 1:29.8xx range for a couple of laps. This was my first time out in this car in 2009 and I was able to go that fast very easily. The amazing part about the slicks is their acceptance of throttle input coming out of the turns. The car would literally jump out of the turns when I would go full throttle. I can only imagine this would be even better in a GT3 with the weight on the rear tires.

For the GT3 they offer them in two different compounds: R100 and R80. I was on the softer R80 compound. The R100 is just as good but a little bit harder. As for DE events I would probably go with the R100 as they will heat cycle better and will last longer.
One big thing to note when switching from the R6 or similar R-comp to a true slick is you might have to change your line through some sections of the track. In the E46 M3 I could always take the curbing on the outside of T5 at Road Atlanta with no issues while running the R6s. When switching to the slicks I had to alter my line to avoid using this curb. The reason is the curb would upset the suspension just a little bit and the tires would try to spin while going over the curb. With the slicks there wasn't enough slip of the tires to make this a smooth transition. The car felt like I was trying to rip the drivetrain right out of it. The same thing would happen over some of the other curbs around Road Atlanta so keep this in mind if you like to use curbs for your fast line around the track.

So Seth, how many laps didit take you to get them up to temp and what length course?
I'm new to these tires And would appreciate the info
TIA

Seth I know nothing about BMW's other than I race with them in NASA. For the 996/997 based Porsche, Hoosier recommends the R80s up front for better turn in, and the harder R100's in the rear for longevity though we still wear the rears out first....

2 laps on a sunny 65 degree day at Road Atlanta (2.54 mile course) First lap is pretty good with decent grip but they really got up to temp on the next one. 3rd lap should be as good as the second.
