Hello all,
I'm new to the boards and about to pick up a 2003 Boxster S, my first Porsche. I plan on attending autocross/track events, and I'm looking for a second set of wheels for this purpose. I've come across some 18" wheels off a 2000 911 C4 with the following part numbers/sizes:

993.362.134.06 (7.5x18-ET50)
993.362.140.04 (10x18-ET65)

The rears are an inch wider than the 18's that are currently on the boxster. I called the Porsche dealer and was told by a sales rep that the C4 wheels won't fit the boxster because they're too wide. I'm wondering if anyone can lend their insight as to whether or not a set of wheel spacers might help me mount these, or if I should just keep on looking for something with a 9" width.

Thanks in advance,
Mark

You can put 10" rims on a Boxster. The dealer doesn't know his *** from a hole in the ground. All you are going to need is at least a 19mm spacer, 30mm if you want to fill in the wheel well. The fronts are fine as is; again you could use a 10 mm spacer to bring them out a bit.

Agree with the comment about the dealer. My dealer told me the same then proceded to insult me by telling me how superior Porsche had engineered my car and suggested I spend my money getting a better alignment or learning how to drive by taking a driver's ed class. Your dealer needs to send their techs over to Rennlist. You will need: 17mm min to 21mm max. 30mm is too much. The exact size you will need is dependent upon your car's manufacturing tolerances, your alignment, whether your tires have rim protection beads and their exact dimensions and manufacturing tolerances, and the exact wheel. I'm assuming you want this to run 285s in the back. The fit is incredibly tight back there for 285s. If you're only going to run 265s, then save yourself some grief and stay with 9" and maybe get some spacers (5 to 10mm) to fill out the wheel wells if desired. Some people use the widebody 993 wheels with a 40mm offset, but with 285s, I think the setup sticks out too much and will rub if lowered. As always, different strokes for different folks, but that's what I'd recommend...

I'd run 225/40ZR18 in the front and 265/35ZR18 in the rear. I don't want to fill the wheel well, I'm just looking to maximize my contact patch on a cheap set of wheels (the price on the C4 18's is cheaper than I've found for anything elsewhere) and tires for track/AX use. Can anyone suggest a good supplier for the wheel spacers?

Can't recommend a brand, but you are going to want ones that replicate the hub-centric feature of the hub, otherwise installing the rim becomes a pain unless you switch to studs.

Q

I fitted a set of Tequipment 18" turbo look rims to my 03 S
[ 18x8 ET50 ]
[ 18x10 ET47]
part # 000 044 600 57

These were a bolt on fit - even with my [large] neg camber on the rear.

I then stripped the 265, and replaced them with 285's
If my car were standard height, the fit would be perfect.
My [large] neg camber on the rear meant i needed to fit a 7mm shim.
I fitted a 15mm spacer to the front to combat the awful understeer i had induced with the 285's

New Topic: Fresh 1987 944 that has been taken nice car of. Including the white 16inch ****s. I like the lookof the Fukes, but I would like a wider profile tire/wheel. What is the naximum that I can push the carwith and not turn it into a clown car. Also, I drive like an old lady. putt to and prone 7-11 on a daily basis. However, I want the coolest car availabie that put on at least an attenot at being a high-end stock model.

Thank davidgproctor@hotmail.com

The ET on the 10" in the rear is too high - you need an offset preferably in the 40s.

You could probably mount them with spacers - I'd go with 20mm.

I had a local shop convert my rear assembly from bolts to long hubs to accomodate spacers in the rear. It was inexpensive and effective.
