I need to find out what the length of the standard lug bolts on my Boxster?

I'm planning to put 7mm spacers on my rear wheels and need to find out what length lug bolts I would require?

Thanks in advance,

Ray

Fix my crappy computer and I'll tell you.

The ruler gave it away.

45mm + 7mm = 52mm

I still can't get your notebook to recover, but I'm still working on it.

Henry has 6mm spacers and he drove 10k miles with the standard length wheel bolts. Until I teased him, and then he put in the 50mm GT3 bolts.

But, if your wheels fall off, don't come looking for me....

I'm buying this wheel and tire package which includes the mounting/balance, lug bolts, valves and shipment to my home for $1812.00

The wheels are ROH Drift R which are a nice clean one piece design with no rivets (easy to clean), nice polished lip and silver center to match my Arctic Silver exterior of my Boxster.

18 x 8 (50mm offset) with 2" polished lip

18 x 10 (52mm offset) with 3" polished lip

I'm getting H&R DR spacers for the rear, hence the need for longer lug bolts (45mm + 7mm = 52). This should put rear wheels at an offset of 45mm.

The tires are Toyo PROXES T1R

225/40/YR 18

265/35/YR 18

Let me know what you think and if there any issues with the rear offsets. Btw, this is not my car, but this is what it would look like on a Porsche

Thanks, Ray

The Cayenne service manual says...

The wheels of the Cayenne are secured with standard wheel bolts M14 x 1.5 x 51.

- Do not confuse the Cayenne wheel bolts with the sports car wheel screws (911 and Boxster)!

- The wheel bolt for the Cayenne has a length of 51 mm, the disc (calotte) consists of steel and has a groove on it -arrow- (911 and Boxster without groove and disc consisting of aluminium. Standard length = 45 mm and GT3 = 50 mm).
