All you smart wheel people need to help me on this one. What size spacers would I need if I bought these for my MY97?

Go 'stros!!!

Info from the auction:

Size: Front 18x8" / Rear 18x10"
Offset: Front 50mm / Rear 65mm
Weights: Front 24.5lbs / Rear 27lbs
Bolt Pattern: 5x130

If nobody has a definitive answer, here's a couple of ways to figure it out.

Ask the seller what the measurement is from the point where the wheel contacts the hub to the outside edge and the inside edge of the rim. Measure the same on your wheels and make sure the spacers make the inside clearance the same and don't cause the wheel to be outside the wheel well.

Another way is to wait until you get them, then put washers on until they fit right then measure the thickness of the washers you end up with.

Nice looking wheels!!

i dont know if this will help, but i have a 2000 box with 19x10 in the rear. and i believe with that 10 inch wheel, you need about anywhere from 43mm to 52mm offset. so you need to add that much of (thickness) spacers. my wheels, made for 996, had 55mm offset, so the inner part of the wheel was touching the shock.
i had bought one of those 5mm spacers and didnt feel comfortable. so i bought a hub-centric adaptor in 15mm. (no choice, on ebay, not many makes 5x130 pattern) works like a charm!! so that makes my rear offset 40mm, which makes it stick out just a bit but it look tough.

Kajita Post some pictures, I have 18X10 in the rears and was looking to add spacers to make it flush with the fender. Did u add anything in the front? Any ideas and pictures would help. Thanks

check out my old thread: http://www.986forum.com/forums/showthread.php?p=18566#post18566

i had 5mm spacers on back then, i dont have the pics with the 15mm adaptors on.
you have to roll the lip on the fender though.

Randall,

This thread may have some useful information for you, http://www.renntech.org/forums/index.php?showtopic=6463, although they are talking about these 9" wide wheels on the rear, rather than the 10": http://www.wheelenhancement.com/index.php?t=WheelDetail&id=43

If I understand correctly that the ebay listing says the wheels are built to the same specs as the wheels linked above, you might want to call or e-mail WheelEnhancement and ask whether these 10" wheels fit on the rear of a Boxster, and how they would do it if you ordered the 10" wide 996 five-spoke wheels from them.

Edit: I notice that the ebay listing has a "fitment chart" that states the offsets. Compare those with the offset info in the first thread above.
