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.

9 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1Original post

I'm a fairly new Porsche owner and I'm looking to install the 20" Carrera Classic II's on my 987. I've seen another with them and really like the look. Will any modification's be required? I know the wheel is made 20x8" & 20x8.5" front, and 20x9.5" & 20x11" rear's. Will either or both fit, without modification and the proper size tire? Will the hub or caliber be an issue? How about the spring perch? What maximum offset's fit? I have no problem with low profile tire's (30 or 35's). Here's the look I'm going for:

POST 2Original post

I wouldn't use 20" wheels on the 987. These are too big and will negatively affect handling due to the weight and very thin tire profile.

POST 3Original post

Welcome, none of the images worked... so the 987 Cayman does not show as coming from the factory with 20" wheels, not to say you can't make them work but you will have to confirm the fit before any money goes down! ? Either find someone who has their car fitted with the size you are looking at or consult a reputable tire shop for guidance.

POST 4Original post

I believe Arch has a whole thread on this topic. He was successful. Use Google to find the link, 20 in Cararra wheels on a 987 Cayman , which exposes another tire gap issue.

POST 5Original post

Yea, a few years back I fell in love with 981 Carrera S IIIs, came across a minty set of new car take-offs, and set about trying to make them work. Plan was to fit 35 series rubber but clearance issues popped up, so 30 series rubber went on and worked fine. Still, I wanted to get back to more sidewall and was set to experiment further once my rears needed replacing. Instead I jumped on the 19” setup in my sig and am completely enamored. Long story short, OP, if it's 20s you want, it’s totally doable. But given the the smaller wheel wells of the 987, you're in for a tire sizing experiment. Here's the old thread... https://www.planet-9.com/porsche-tires-and-wheels/95292-981-20-carrera-s-iii-wheels-my-987-2-a.html In fact those wheels are now garage art. Gotta get around to selling 'em!

POST 7Original post

Thank you for your input, buddy. I'm reviewing your thread, now. What was the most significant reasoning, moving back to a 19? To clarify, were they OEM or aftermarket? I'm having significant troubles locating an aftermarket/replica, of the 20" Rad Classic II's, in 8" & 9.5".

Nvizn, you might check you photo work after posting. You can always go back in to revise/correct the picture quality or delete the post.

POST 9Original post

I alway's check and confirm. It was displaying, immediately after posting. It must be some problem with this forum, and Google Photos. I'm able to post from the same folder, on another forum, no problem.

This is a source reference. Confirm exact model applicability in the original material.
