Another wheel fitment. Please Help

Hi Guys,
you are probably tired of this wheel fitment question, and yes I already did a search, and did not see a question like mine. I have a 97 Boxster, and currently use the 17 standard "twist" wheels. I am looking at a set that came off a 99 Carrera Cab. Will these work?

Front- 225/40-18 offset (7.5/50)
Rear- 265/40-18 offset (10/65)

I dont want to purchase any spacers if possible. What will I need?
Thanks

Here's a great application guide I used when I bought my aftermarket wheels...

http://www.wheeldynamics.net/appguide.html

Your fronts will probably be fine, but the rears will require a 15mm spacer. Our cars require a 50 mm offset to clear the struts.

I ran wide spacers in the back and had no problems, but did find that any wheel imbalance or tire issues were accentuated with spacers on the rear end.

thanks,

Those wheels in your pic are Sport Classic IIs and you can get a factory set made specifically for Boxs with the proper offsets. Then you don't have to worry about the wild offset and big spacers in the rear using SC IIs from a Carrera.

Boxster SC IIs pop up for sale here and on other forums or you could check ebay (be sure to know the offset before making any bids - ads will say they fit a Box but only if you use spacers). The proper offsets for 18s on a Box are 7.5 / 50 front and 9 / 52 rear. I sold an average cond set for Boxsters last yr for $750 - with the depressed economy you may be able to find some for less. They look fantastic on a Box but they are a pain in the a$$ to keep clean.

Take your time and get the proper size.

Rear tires for 986 should be 265/35/18, 265/40/18 is about half an inch too thick.

+1 on that thought, which I had after I saw your pix but didn't make the comment public until now.

Our brake pads create a lot of highly charged metal particles that are "sticky" and will make clean rims look dirty in less than two hours of driving. On these rims, that's a lot of extra work to get into all those nooks and crannies to clean them properly.

Be sure to use some good wheel wax if you buy them to cut down on the brake dust buildup.
