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 · 1 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

Does anyone know why my 07 manual pgs 191 and 302 give the weight limit as 132lbs for the roof rack and the Porsche site says you can put 165lbs on it?

POST 2Original post

Does porsche .com say you can put 165lb on it when it's on a Cayman ? The same rack is used on the 997. And I think the big roof box ("Roof Box 2" IIRC) that would mechanically mount, is intended only for the Cayenne. Mainly -- don't trust Tequipment listings regarding model-specific limits. On porsche .com, and on Suncoast and Carlsen's sites, there's a lot of careless cut-and-pasting.

POST 3Original post

I can't explain the discrepancy. However, I can tell you that I've been using the Porsche roof rack to support a plywood platform on which I attach my four track tires and wheels. I've driven 400 miles each way to and from the track with this system and I have not experienced any problems with the rack or the roof mounts. The total load on the rack is close to 165 pounds.

POST 4Original post

Them's mighty light track wheels and tires, jonathan. What are they?

POST 5Original post

Yes, the roof rack for the Cayman is rated at 165lbs on the website. And I've weighed stock wheeks with hoosier race tires at 42fr/45rr, so 174lbs all in. So if 165 is OK, I'll assume the factor of safety covers 174.

POST 6Original post

Jim Michaels: I use BBS RS-GT 18" wheels and Toyo RA-1 tires. Iweighed them last fall. I can't remember the exact numbers, but I was very close to 165 lbs. including the plywood platform and hardware.

POST 7Original post

Thanks, jonathan. For those considering the roof rack for their OEM wheels and tires (or with Michelin Cup tires), the set would weigh about 20# more than jonathan's. With the GB RAC Monolites and 235/265 Michelin Cups, the weights would be back down to about 165#. There's probably some safety margin beyond 165#, but I wouldn't want to test to find it on my own car.

POST 8Original post

I did a bit of investigating, and found that the Porsche website for other countries/regions (mideast, austrailia, etc) gives the roof rack rating as 60kg/132lbs, while the American site rates the apparently identical (same part #) unit at 75kg/165lbs! Go figure.

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