Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

The rear tires on my car are 295/30 which is the size Techart uses for their 19's.

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 1Original post

Would 20x9 Front / 20x10.5 Rear fit on the CaymanS? I plan to put H&R spring also and just wondering if it would easily fit. Thanks........ Mauiogg88

POST 2Original post

if the offset is right...then yes. if the offset isnt right....they might just plain ole not fit or u may need a spacer

POST 3Original post

In this case do you think it will fit without spacer? Thanks

POST 4Original post

I have 19" Techarts on my car. Techart also offers 20" wheels. A rear spacer of 15mm is required although no fender rolling/mods for the 19" wheels. The 19" (and I believe also the 20"s) are 11" wide. The rear tires on my car are 295/30 which is the size Techart uses for their 19's. This is just my opinion, but I don't think 20" wheels look too good on the Cayman, they seem to work better on the 997 version of the 911. Check out their website ( www.techart.de ) for more pictures and information. Hope this is useful.

POST 5Original post

i know for a fact that the techarts 20 x 11's need the 15mm spacer....there's no way for us to know for sure unless someone has had experience with the offset of those rims. I would suggest calling some wheel and tire shop and asking them if u need a spacer or not

POST 6Original post

it fits. myfront 20"x10 and rear 20"X11.5 with 15mil spacer.
