2 questions about Wheels and Brakes

Recommended Posts

I have a 97 Boxster with factory option 030 sport suspension, the motor has been replaced with a 99 3.4L from a 996. I would like wider wheels on the rear I'm going through rubber quicker than I like.

I would just like to verify that the wheels off of a 993 turbo will fit this car. 10x18 et40 rear 8x18 et52 front I have read that you can and can't put 18's on 97. From what I have gathered this has something to do with a weak frame not a physical fitment problem. I'm not taking this car to DE or anything serious, just fun driving to and from work so a small risk of bending something would be acceptable to me.

Next I'd like to upgrade the brakes with the most feasible swapping options from other porsches. If i have to paint the calipers to match it is no biggie just looking for your guys opinions on something larger but balanced and maintainance friendly.

The 18's will fit. 225 up front and 265/285 in the rear.

While there is a chance of body cracks in a 97 you should be okay. Don't hit a lot of pot holes.

You can put S or 996 brakes up front with no problems. The rears require either machining or wheel carrier replacement.

Good deal,

Any info on what wheel carriers will fit I'm guessing an S but again just guessing or any details as to what machining would be needed I just happen to own a pattern shop. I would rather have a nice solid servicable solution rather than a bunch of adaptors and whatnot.

Also would the current rear brakes be fine with just upgrading the fronts?
