Autocross R-Compound Tires???

[grantsfo]

245 is awfully skinny for AX. I'd run 275 square. However my favorite setup on Boxster was 315/30/18 and 295/30/18 a6s.



If you're not ready for DOT R tires Hankook RS3 is awesome ax street tire and they make some good sizes for Boxster with 17s too. NT01 is nice treaded DOT r tire that will be much more forgiving to your wallet.

They are on sale at Performancetread.com now too.

Where do you plan to autocross? Do you run with RSCC ? Be carful about compounds you choose if your running at cold venues. road race compounds like Hoosier r6s need heat to work well in ax. I'd say two best dedicated autocross tires are the Good Year Eagle RS DOTR in AUtocross compound and the Hoosier A6 DOT R. In cold weather the good year actually works better!

The car in the post above me has GT3 front bar, Tarett long links, and Tarett rear bar.

KW shocks, Tarett monoball inner pivot's on stock GT3 control arms.

Tarett rear toe links (monoball inner only)

It performed VERY well at the SCCA Nationals **She** took second behind a SoCal BMW, I believe he took 3rd behind the same BMW in the men's class and something else.

Grant will have to confirm. I was standing there.. but I have slept since then

Think about this ....the boxster had stock 2.5 internal motor against the the national winning BMW and 240z with fully built race motors. The Boxster was driven by two guys with little seat time in the car. I hadn't driven it for 8 months and jumped in new tire setup.

Fast driver in Boxster beat both Larson BMW and the 6 time national winning Thomas 240 z on more technical course which was very impressive! We actually had Thomas until his last run on day two. Stock powered Boxster couldn't hang with them on more power focused east course the day before. So it has beat the Larson car in a one day event.

Car was third in nationals in FP with time very competitve to winning BMW. With a built 2.7 the car will be a winner in FP class.

Just think what it would do with set of good JRZ shocks, full monoballs, and a 2.7 built to class specs.

Dude if I had the car right now I'd be in So Cal working with you to get that motor in the car. I'm busy now putting supercharger in the Z.

Hi Grant,

did you ever end up selling Frankenboxster?

[Brad Roberts]

Hey wait!! I cant have two Boxster's named "FrankenBoxster" LOL

Grant sold his car to a Dr. in Austin Texas and the *other* FrankenBoxster (SCCA BSP CaymanS powered Boxster/986) sold to a guy in Washington.
