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.

Of course, still just my opinion from others that have used spacers and have trouble with the tires rubbing' or hitting the fender's edge.

Dude, if you have the OEM C4S 11 inch wide turbo twists, then I wouldn't advise using spacers.

I know people use spacers all the time, but going with 20mm to me would be beyond the threshold.

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.

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

POST 1 / ORIGINAL POSTEROriginal post

Would like 10mm up front, but can't find 10s , might have to go with 7mm ... will 20 in the rear and 10 in the front be acceptable ?? (looks like most go with 15 & 7 mm sizes) .... thx Brad

POST 3Original post

I went 18mm rear and 10 front in my Carrera. ECS Tuning has full kits in all these sizes, and the fabrication is excellent. https://www.ecstuning.com/Porsche-20...heels/Spacers/

POST 4Original post

Please explain why wheel spacers to a complete n00b Why are they needed? Do they change the stock geometry?

POST 5Original post

They usually just fill in the wheel wells by getting tires out closer to the fenders. It's an appearance thing. Edit: or when your 245/40/18 NT01s rub the coilover even though the same size in hankook z214 doesn't.

POST 6Original post

Dude, if you have the OEM C4S 11 inch wide turbo twists, then I wouldn't advise using spacers. IMHO

POST 7Original post

IIRC Porsche specs 5mm front spacers and 17mm rear spacers as max allowable. I picked up a set of 7mm/17mm spacers here but have not put them on as I also picked up a set of 19" 997TT wheels that fit well. I will use the spacers if I ever install the Kinesis 18" K19s I picked up or reinstall the OEM 18" Techno Twists that came on the car. I might have an extra set of 17mm spacers out in my garage.

I meant to say "20mm spacers". I was typing on mobile. I know people use spacers all the time, but going with 20mm to me would be beyond the threshold. Of course, still just my opinion from others that have used spacers and have trouble with the tires rubbing' or hitting the fender's edge.
