Chris from XTR: If you could PM me pricing on the AP for a 2007 335i I'd appreciate it.
Unfortunately, you may only be able to run stage 1 drive in CA, as many have found stage 1 sport to be too aggressive for ACN 91 gas (AZ, CA, NV). Stage 1 sport will work, but you'll probably be pulling timing under WOT.
