wheel spacers

I would avoid these as they need longer studs.

Better to use the ones with 10 holes and separate studs.

An 87 Lux with early offset should have the following sized wheels as standard:

Front 15x7" with 23 offset
Rear 15x7 with 23 offset

The S2 Design 90s should be:

Front 16x7 with 52 offset
Rear 16x8 with 52 offset

If you use the calculator at http://www.1010tires.com/WheelOffsetCalculator.asp it shows that the front wheels are now 29 mm closer to the strut so you need a 30mm spacer.

The rear wheels are now an inch wider so the inner edge is 42mm closer to the strut and the outer edge is 16mm further away from the wheel arch. If you have plenty of inner clearance then you need a spacer to at least bring the outer edge of the wheel back to where it was before.

n'est pas?
 
All PDC is 5 x 130. You need circa 30mm spacers to fit late wheels to an early car to get them where Porsche intended.. You'd want a bit more to get D90s to fill the arches. It's pretty simple though; how much further out do you want the rim? That's the spacer you need.

It would be cheaper to get wheels that fit I suspect.
 
Re they defo all 5x130? I read somewhere some were different and were 5x108 but was not sure, Ive not had a chance to go ,measure for myself as im lazy! [:D]

So am I right in saying that the original fuchs wheels would have sat out further on my car? but if you were to put them on a later 944 they would have sat too far out?
 
Definitely 5 x 130 and yes, the Fuch wheels would fit your car and stick out too far on a post '87 one.
 
cool :) thanks Fen!

Ive just got mack form my workshop and polished, cleaned, tweaked almost everything i wanted to get done, even had it over the pit and checked out underneath and my god its tidy!

Also fitted my mp3 head unit and the best bit...... I fitted my azev A's, I wasnt convinced the offset would be any different but I was so so wrong, there ET 20 at the back and ET 20 at the front and they sit just right :) its a shame there so tatty as they really would look great! I think im going to refurb them over the winter :)
 
Strange. i was under the impression that the pcd changed on 944's at some point aswell. Wonder why that was.
So Fuch's, Cutters, teledials, D90's cup's etc are all 5x130 then?
 
The PCD changes on 924s as the early 2.0 models were 4 stud. The 944 has been 5 stud from day 1 and all Porsches with 5 studs have a 130 PCD as it was carried across from air-cooled VW.
 
Cheers Fen, thanks for putting me in the light. But you've getten the air-cooled thing wrong there. Both VW and porsche had 5x205 to start with. Porsche changed to 130 by the looks and VW went to 108, but much later on. VW do have a 130 but it's 4 stud. I can't take Porsche wheels and stick them straight on my VW's, i need adaptors. Unless i get a 356, oh if only eh?
It makes you wonder though why there are so many different stud patterns. Why is that. A universal, one size fits all, seems a logical step but obviously there must be reasons why different manufactureres prefer different set ups.
 
Well I didn't know that. I thought Fuchs and Cookie Cutters etc. went straight on to Beetles and camper vans.
 
I believe the thickest you will get from a proper Porsche supplier is 7mm.

After many years of "Shall I, shan't I?" I fitted 7mm spacers on the front of Beaky. They seem fine and they were only to bring the 993/Boxster wheels back to the correct offset of "proper" 944 wheels.
 
Thanks John. Is that the point where i would need to look at getting longer wheel studs due to there being insufficient thread left for safety?

Simon.
 
7mm is the limit for shims, but you can go much bigger with "proper" spacers. These bolt onto your hub, and you then bolt the wheel onto them, so no need for longer studs.

 
Can I just clarify if you guys are saying we could run 7mm spacers on top of the std porsche spacers that are on there??

if so i think my Azev's will sit just nicely as there ever so slightly in from the arches!
 
Really!? Well if that's the case every day is indeed a school day. I had always thought Porsche, especially in the 80's, were an engineering company as much as a car maker. Why didn't they just use wheels that fitted the car?

Regardless I would doubt it's a great idea to add additional set even if the factory sent them out with spacers from new.
 
I would suggest you are playing with fire if you fit shims on top of spacers [:eek:]

The best thing to do (and also the most expensive) would be to measure your current spacers, decide how much further out you need your wheels to be then buy a proper spacer of the correct size. Design911 and others sell a range from 15mm up to 75mm from £100 a pair to £195 a pair
