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'm looking for a set of turbo twist wheels for my 99 C4. The car came from factory with option 413 Turbo Twist solid spoke wheels originally but these were changed at some point in its life for GT3 splits. I can't find any information on the size the option 413 18's would have been but assume 8" front and 10" rear? I've found a set of what I think were Boxster fitment wheels fronts are 7.5J x 18 - ET50 and rears 9J x 18 - ET52 Will these cause any fitment issues? Too narrow? What size tyres do they need? Any help, advise or opinions welcomed!

POST 2Original post

The will sit in exactly the same place as the original wheels as the rear offset is lower to counter act the reduction in width. Note that a 265/35 rear tyre also sits nicer on a 9in wheel than a 10in wheel, always found a 265 very slightly stretched on a 10in on some tyres. I run the same sizes on my car albeit I ahve 15mm spacers all round for aesthetics. Note there are some Boxster wheels that come in 10in et47 which will sit very nice in the rear.

POST 3 / ORIGINAL POSTEROriginal post

Thanks! Now looking for some All Season tyres. What size tyre do you run on the front presuming same 7.5 wheel?

POST 4Original post

I have an 8in front and 9in rear. I think the front offset is et52 though. They are Panamera wheels.
