Yes, a good info source. They list P Zero N1 rear at 30 lbs also. My partially worn rear takeoffs weight 29.2 and 28.6 lbs. My very worn front tires weight about 2 lbs less than the listing.

Kudos for Porsche to ask the BBS to produced a light wheel for us.
if you see other wheel weight:

even the BBS 19 from the link, seems heavy!!
in any case, I'm in the middle of upgrading my wheels and i don't want to be too much heavier than factory setup. That being said, I've no idea what is a good tolerance to be acceptable either. 1lb? 2lb?

If you want light wheels, get Carbon Fiber ones - be prepared to get out your wallet, though. Also PCCB brakes take quite a bit of unsprung weight off the wheel.

20-inch carbon wheels + PCCB would be the ultimate un-sprung weight reduction solution. Any sources for 20-inch carbon wheels in 9-inch and 12-inch width? Even 8.5 and 11.5 inch width would work.

I just ordered the set of HRE (20" / 3pc) with OEM sizing for my C4S, when it gets here, I will update with the weight difference. take a photo of it and see....

We've got Carbon barrel options from Forgeline as well as HRE's R101 Lightweights that are the most lightweight custom forged aluminum wheels on the market. Third on the lightweight list is of course the BBS FI-R's. We've got info on all of these for those interested.

My car came with Sport Design II wheels. Before I got them refinished and taken all the hardware off I weighed them on a pretty accurate scale. The following weights are for the bare wheel with the TPMS sensor and center cap:
Front
8.5Jx20H2ET51
9913621613288Z
25.4ibs
Rear
11Jx20H2ET52
9913621663388Z
31.3lbs
Front
8.5Jx20H2ET51
9913621613288Z
25.4ibs
Rear

somewhere, I saw some OEM wheels are forged processed and made by BBS, is this true on your wheel?

I believe they are made by BBS but I don’t think they’re forged. I now have a set of BBS FI-Rs on the car that are forged and they are considerably lighter than these Sport Design IIs. Though I do really like the look of the Sport Designs.
