19X10 ET 37 on 986S rear?

I've got a 2001S and am currently drooling over some 19" wheels that have a 2.5" lip but only a 37 offset.

It looks like folks successfully run 40 offset 10" rears from other P cars, but the offset doesn't tell me how wide those wheels are from the hub to the outer rim. I'd plan to run Michelin Pilot Sport tires in 265/30/19 for the rear if I get these.

I'm wondering would this slightly less than 40 offset and 2.5" lip would clear the fenders?

Anyone have a setup like this on a 986?

19's were not an option on the 986, so you'll have to find folks that have tried them which is a relatively small number.

you've tried this?

Thanks guys. That calculator is useful Dlirium. I guess the thing I wasn't considering is that the offset measurement is from the center of the wheel so the amount of lip doesn't make a difference since there should be half of the wheel on either side of center. That was confusing me since they are 3 pc wheels and I had the outer barrel measurement given.

It looks like it would be very close, and may come down to the tires if I get these.

Cheers,

The smaller the offset number, the more they project from the center of the car.

The opposite of what one might think.

Sorry for the slow reply but here's the link that answers a lot about wheel offset for the Boxster 986. Just look at the pics of Johnny Danger's yellow Boxster with 19x10 with 31 offset at the rear. 19" vs. 18" Wheels/Tires
Wish I could use 19" but mine's a '97 base so it's wiser to limit the size to an 18"
