boxster o/s rims on sc body

[favrok01]

What spacers would i need for boxster offset rims on a sc body?

[Yellowbird RS]

I'm running with 31.7mm (f) in a Boxster 17' 7.5j, 55 ET and 31mm (r) with a 17" 8.5 j, 48 ET

[favrok01]

Ok so if there is 25.4m in a inch i would need 44.4(f) and 56.4(r).
This is becouse i have 8" (f) and 9.5 (r)

Is there such a thing??

Where do i get them??

[Yellowbird RS]

check the ET of the wheel (in mm) then you need to do some maths to find the spacer wide you want, you need 23.3mm front and 17mm rear

[favrok01]

Here they are!!!

If I have rubbing of the inside rim on the strut tower what would you advise???

.24

.5

1
or your 31.7 millimeters = 1.2480315 inches

to clear the strut tower?

[Oh Haha]

Do you know the offsets of the wheels?
I am running 1.0 and 2.25 spacers on mine with the 993 wheels with 52mm front and 70mm rear offsets. 16x7 front, 16x9 rear
Those wheels are killer but the spacers are expensive so be sure to get the right ones the first time if you do it.

Hey oh Haha

I wish i knew what the offset was... its going to be hit or miss at this point i am afraid as i am sure you are starting to tell my Porsche life is never easy.

i just called Kinesis and found out my rims are a sand which typ which means they have the the center piece dead center.

My off sets are 39mm (f) 52mm (r)

[Yellowbird RS]

So you need to mach the front to 23.3 mm and the rears to 15-17mm.
39-23.3=15.7mm front
52-17=35mm. rear
note this is for 17" wheels

[favrok01]

yes yes I have done some measuring and 15mm in front is dead nuts on!!!!

but...

The rear are pretty damn BIG i brought it out to the end of the lugs and still had the bolts on the arms sort of nicking the tire.

soooooooo....

Since the lugs are about 1 inch i think 1 1/4 will just do it...i hope.

actually your dead nuts right about the rear too!! 35 millimeters = 1.37

so a little larger than 1 1/3 i know those bad boys are going to be sticking out ....DAMN!

These guys custom make spacers for all makes and they are less expensive than everyone i have looked at....

Custom Spacers

Has anyone posted a definitive chart or other reference compilation showing interchangeability with various models wheels and spacer requirements?

With original Fuchs prices for the 74-89 models going thru the roof, their age, limitrd sizes, etc, many budget minded enthusiasists are looking to use OEM wheels from other/later model P-cars to use for track or winter tires. (Apologies to the purists out there) For example, what do you need to adapt turbotwist or C2 wheels to an SC with regular flares. Which phone dials from the 944 or 928 work? What offset/backspace numbers do we need to look at.

Granted, there are nice custom made wheels out there like the Kodiaks or Lindseys, but at $1600/set and more, many of us are looking for something OEM that we can use.

About the only thing many of us are sure of is that the bolt pattern is a 5X130mm unique to Pcars.

Well here is a answer

15mm (f) 37mm (r) for boxster rims on a SC

[favrok01]
