really its that simple??? I read on wheeldynamics.com that ill need a 7mm spacer for the front and that i will have to flip the strut mount bolts upsidedown to fit in 18's. or is that only for an 86??? im completely lost... and i figured that you guys will lead me in the right direction.

I have been through this many times on my '87 951. The ET47 10" rears will not fit and you cannot use spacers. You need ET65 10" rears.

The ET50 8" fronts should be ok.

well heres what they say on wheeldynamics.com:
"No spacers needed for newer17"- 18" wheels in the 48 mm-65mm et range. All 986, 996, 997, part# wheels will require a 1/4" (7mm) for the front hub. This is so the wheels will mount flush on the hub. This is needed for all newer wheels."

Since the fronts are 50mm they should be fine...right?? as for the rears they are a 47mm so wouldnt i need a spacer thats anywhere from 1mm-18mm???? Please help me because right now looks like i made a dumb decision...

no its the opposite. you will need to shave 1-8mm off the wheels to make them fit. Obviously you can't do that, so they wont fit.

for a complete guide on understanding wheel offsets read the whole section under 944 wheel FAQ on this site http://members.rennlist.com/951_racerx/

ok i understand the rim hitting the caliper, thats why you woyuld use spacers, correct? as for the rears i would have to shave off 1-8mm so the wheel will be able to clear the lugs?? if thats the case then could i not install longer lugs?

Airflite40

No its about the rear fender hitting the rear tire.

you could probably fit them if you CUT the rear lips off the fenders and then you still will probably have to roll/stretch the fender a little...

mr944

even if im running 265's on the back?? right now i have 225/40/18 and 265/35/18... i gotta say thanks airfilte once again the polaks are going outta their way to help me out. I owe you a tyskie

Airflite40

its possible with the 265s it would fit. Its gonna be close though.

Na Zdrowie!!!!

Believe me - the 47mm offset 10" rears will stick out beyond the fender by almost an 1 inch, regardless of the tire size. It will look ridiculous and tires will rub and tear up your sheet metal - so, they won't fit

The 5-7mm spacer on the front is required on *some* wheels to make the center hub fit correctly. 944's have a large wide wheel bearing cover that interferes with the inner hub area on many late-model Porsche wheels. Cup and twist wheels are fine, but other Boxster and 996 wheels will not bolt on. The spacer gives just enough clearance to allow the bearing cover not to interfere. The 50mm offset itself is ok, but barely IMHO, and adding the spacer pushes the wheels further outward, which is the wrong direction.

Note, fitment here has nothing to do with brake caliper interference - that is not an issue at all.

I know all this because I bought a set of wheels intended for a 986 (Boxster) with 8" ET50 fronts and
10" ET45 rears and it was a disaster.

I now have 993 twists, 18x8" ET50 and 18x10" ET65, and they fit perfectly. BTW, I'm running 225's on the front and 265's on the rear.

Hope this clears things up.

I had 18x10 on the rear with 55 offset and put a 1" spacer back there. There is alot of room back there.

With your '88 or '86 ? With late offset 944's (1987 onwards) I don't think this
would work at all (the 1" spacer makes it equivalent to a ET30).

Airflite40

The wheels I bought from DDP are 18x10 rears with a 48mm offset and they fit on his 87, but rubbed.

I can't remember if he rolled the fenders, I think he did. He also had 285's or 295's on there.

A 47mm offset is only 1mm further out, so I think they will fit but its close.

zoltan944

Yes, I must point out that a 255 would be best here... 265 should work too
