Oh, Bernard, I think you confused us with your two posts...
Post # 27 you said....
Then Post #30...
But we know that you have had a LOT of 930 & 964 Turbo's,... so you are forgiven for getting them all mixed up! 
So then yes, our setups were the same. But again, with the lowered stance of mine, I have to be at -1.8 degrees of camber in the rear, so that all hard cornering does not rub the outer fender lip.
And given that a ET54 for a 10" rear rim still allows extra room on the inside of the wheel housing,... I'm thinking a ET56 - ET59 is a slightly better offset.
Hey Jim D, it sounds like the original Speedlines in a 10" wide rim, were slightly different than the RH Alurad's ET54? ...
Can you re-confirm what the ET was for the original Speedline rear 10" rims?
I'm just wondering why RH Alurad decided to do ET54.

Stock Speedline wheels for 965 964 wide body C4 cars is ... and in the rear 10.5 is not too difficult 56 ET 10.5 is another size rear I build. ... Jim jdorociak@gmail.com

Original Speedline 3.6 Turbo wheels were 52 ET 8" and rears were 61 ET 10" - Speedline uses wheel centers that have a different pad height when comparing a front wheel center to the rear center. The rear centers have a + .25" additional height on the back pad area where it bolts to the car. So Speedline rear wheels are 1.75" rear outer rim + .25" crush seal ring + 8" inner rim ----- RH 3.6Turbo center uses the same center to make a front or rear wheel. RH rear wheel is 2.25" + 7.75" (no seal crush ring is used in their design). These 5mm spacers some of you are talking about are really just visual adjustments for owners who feel if their wheel combo was just a little bit further out would be perfect in their eyes. jdorociak@gmail.com Jim

I am running RUF Speedlines 18x10" ET61 and 18x8.5" ET61 (currently with 275 and 225 but have run 285s with stock camber - plenty of room). This makes the fronts in particular look quite in-set with the 61 offset. Am I right in understanding that running say 5mm spacers on the front would effectively make them equivalent of ET51? or ET56?
Is there any difference to the hub set up in reference to the fenders between the 3.3 and 3.6 turbo?

When I switched to 235's I went to 6 mm spacers so the tires were centered in the wheelhouse and didn't rub the inner body or rolled fender lip.
Out back I maybe could add 5 mm spacers to the rear but I haven't got around to trying it (maybe this winter when I need a project to do
).I'm pretty sure that the front suspension is common between the 3.3 and 3.6 and the rear suspension uses different trailing arms between the two models but shouldn't affect what tire size you want to run.
