A few questions for those of you that have been tracking your Spyders regularly.

1) The Brey-Krausse rollbar extension for the Boxster is not compatible with the Spyder due to the SunShade. Is anyone aware of a different solution?

2) R-compound options are limited for 19" wheels. Is anyone running an 18" for the track? If so, what wheel have you decided on and which tires are you running with it?

3) Which brake pads are you running?

Thanks in advance for the help.

Answers really depend on your DE experience and what you wish to get out of DE's. What's your driving experience at DE/HPDE? Two ends of the spectrum is: complete newbie to race-body licensed (SCCA/FIA/etc.). Where do you fall within this spectrum?

I drive a Cayman S but it is basically the same platform. As far as wheels go, a used set of Cayman or Boxster S wheels in 18" is a good way to go. You can go lighter and spend more money. A used set of OEM wheels on E-Bay should run about $1000. I run PFC 06 compound brake pads, but there are a lot of other good choices such as Pagid Yellows or Hawks. I don't know about the roll bar extensions.

Thanks guys. I'm actually asking for my Dad. He runs in the Intermediate/Advanced groups at HPDE days (usually with the PCA). I think he has driven the stock setup to it's potential. He really should have proper track pads now and the street tires are holding him back at this point.

As far as wheels go, are there any offset issues to be aware of or can we just pickup any set of Cayman/Boxster rims? Also, are people running square setups or keeping the staggered tires?

Thanks again...

Cayman S 18" wheel offset is 57 F and 43 R. According to my 2007 manual, the 19" offset is 57 F and 46 R. I have never seen a 987 run a square setup. You can look at 235 F/265 R or 245 F/275 R. I have run MPSC and R888 and prefer the Michelins but some caution that the available rear tire is too small in diameter.

Savyboy started a good thread on this a while back:

I'm running pagid yellows on the spyder. Looking at the Forgeline EV01 18" wheels as well to run either Hankook C51's or Hoosier R6's. Your father might want to consider camber plates and/or GT3 CA's for further negative camber. If not, at least get a track alignment to maximize available negative camber from the stock setup.

After riding in a completely stock Cayman R around Sebring, driven by a Porches Sport driving instructor... I learned that the stock car is extremely capable. The driver with the car had to problem catching up to 997 GT3RS on R compounds and getting the point bys.

Track pads will help shorten the stopping distance. As for R compounds tires, is your dad comfortable driving at his limit with stability off? The thing with R compounds is that when the tires let go, they let go without warning.

I should mention that this is as much a street car ypto him as a track car, so we're probably going to stay away from very aggressive alignment settings, at least in the near term.

Bill Lehman

i suggest that you reconsider "aggressive" track alignment. The most camber you are likely to get with the OEM parts is -1.0 in the front. I'm running -3.2 with a car driven on the street. There is a lot for room for compromise. Increasing camber will help understeer and give much longer life to your tires. GT3 LCA are a good way to go. They are two piece and camber can be changed by adding shims between the parts. Start with -2.0 in the front. You can get close to -2.5 in the rear with the OEM parts.

How much of a concern should the smaller diameter be?
