I recently replaced all 4 struts with Bilstein B6s and stops.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I have a 1999 911 Cab and I need to purchase new wheels because someone (no name I should mention) hit a pot hole and bent front and back rims on the same side (probably original twist wheels). Currently, the car has 7 J wheels on the front with an offset of 55. Front tires are 205/50/17. The rear has 9.0 J wheels with offset of 55 wearing 255/40/17. I would like to move up to 18 " rims with a 7.5 J on the front and 10 J on the rear. The front wears a 225/40/18 offset of 50 and the rear has 265/35/18 offset of 65. I recently replaced all 4 struts with Bilstein B6s and stops. How can I determine if the new wheels and tires will actually fit? I am purchasing the BBS from a private individual in a different state and would like to know how to determine if they will fit. HELP please, 911 Pirate

POST 2Original post

Those are standard 996 sizes for 18� wheels. They will be fine.

POST 3Original post

Yeah...in fact I have GT3 wheels and they are even bigger. I think they 8.5" with 40 ET and the rears are 11" with ET63....on my rears I also use 5mm spacers...all fits perfect on a 996.1 C2
