Greetings,
I purchased a used 2001 S six years ago and started slaloming in Birmingham with the SCCA after a 23 year layoff from autox. History is 914s and 911s autox over 12 years, Western Wash Sports Car Club, PCA, and SCCA.
First question is autox or track days? Who sponsors events? What class do you want to run?
I run "B Stock" in SCCA, but next year rules put me in "B Street" with 140 UTOG tires, raising to 200 UTOG in 2015. Any "R Compound" tire will be in the new "Stock" class for 2014. In 2014 "Street" about the only real changes you can make outside of factory options and combinations are wheel spacers (1/4" or 6.5 mm) and change one sway bar. Any more than that and you get bumped to "A Street Prepared" with all the newer Porsches and Corvettes. Wining in B Street against the Honda S2000s is hard enough. If your're not running SCCA, you can forget most of the above, but I suggest you check the rules first (New 2014 SCCA rules not yet published) and decide what you want to do.
Where in the Nashville area are you going to run - I have a son in Nashville with a Suburu WRX he wants to start slaloming.
Also suggest you get on the SCCA Tennessee Region Forums
Tennessee Region Sports Car Club of America • Index page and contact "Han Solo" who drives an ASP Boxster and and AS Cayman.
Good Luck,
Your original question:
Some of the factory oem wheels are as light as you will find (turbo with hollow spokes)
You'll need 17" wheels to clear the brakes = lighter, lower gearing, cheaper tires
I run Hankook RS3s daily plus slaloms, 255 & 225 X 17, very happy with grip and longevity.
