Proof of factory installed option
 

I need help from all you Boxster experts. To use the factory 5mm spacers for autox (over and abover the 1/4" offset that the rules allow) SCCA requires that I prove that they are a factory installed part. Having it on the ordering guide or in a sales brochure is not good enough. I have already looked through the CDs of service manuals that I have with very limited success. Does anyone have access to a later manual that shows them?

Thanks
Alan

Can't you show them your window sticker?

Alan does the extra 5mm help you in auto x's?

Do you know where the option sticker is on the hood of your car? Look for one of these codes:

IXRN 2 x 17 MM WHEEL SPACERS ON REAR AXLE
IXRP 4 x 5 MM WHEEL SPACERS ON FRONT/REAR AXLES
