245's all around for AX?

[silver arrow]

What were the optional wheel sizes from the factory on a 2000 Boxster? I'm looking to get R comps for my Boxster soon and want to stay with 17" inch wheels, but they aren't very wide. Was hoping to get some big rubber. Being classed in AS for the base 2.7 Boxster is bull. I was 2 sec. off the pace on well worn Bridgestone RE750's (treadwear rating 340 :dance: ) against S2000's and STi's on R-comps.

Not convinced of the larger bar in the front, but does anyone know the part numbers for the Koni DA inserts for a Boxster and if the 030 springs are considered a factory option or dealer installed option?

If autocross in the Boxster today. Very long gearing compared to my 05 STi. Down shifted to 1st quite a bit, though that may have been due to lower cornering speeds because of the Fred Flinstone RE750's?

Where is the best place for Boxster autocross information on the web?

available tire options were:

205 / 255 on 17x7", 17x8.5"
225 / 265 on 18x7.5", 18x9"
225 / 265 on 18x8", 18x10"

M030 is a factory installed option. larger bars front / rear help a LOT; too large in rear will get you wheel spin on tight exits. don't personally know anyone who's done koni inserts, so no clue on the part numbers there. get an aggressive alignment pronto.

great info on the boxster racing board here:

18x8 / 18x10 were not available stock on Boxsters. Some dealers may have installed them, but they were not factory available. Your only wheel choices in terms of STOCK wheels are the first two insite listed above.

Koni does not make inserts for the 986 Boxster.

Does anyone have the offset of the 18x7.5", 18x9?

50mm front, 52mm rear

They're listed in the manual for the purpose of identifying the hollow spoke 18 x 8 / 18 x 10 versus the 'turbo look' 18 x 7.5 / 18 x 9. But interestingly the size they list won't even fit on a boxster (18 x 10 et 65) without spacers. They make no mention of it being an option.

yeah, that wouldn't fit.....

oddly, my manual (downloaded from renntech) shows the 18 x 10 with an ET of 47, which WOULD fit a boxster. 65mm is the 996 offset for that wheel. it would be nice if this were an acceptable wheel combination.....

i bet since it's listed in the manual, some organizations might buy off on it as being okay....

I was looking in the shop manual. I just downloaded the owners manual. You may be right, it may be sufficient for some organizations. Hm...
