Euromeister 8s or 9s

[dynosoar1]

Hey guys...83 SC coupe....I'm looking at putting on a set of Euromeister 17s....gonna go with 7s (et 23.3) in the front but my question is should I go 8s (ET 10.6) or 9s (ET 15) in the rear. I don't want issues with having to roll fenders or messing with spacers and just wondering if the 9s will fit or if the 8s are better for the rear. Looking at putting on 255/40/17s for tires in the rear. By my calcs it seems the 9s will bump out the rim and tire edge about 0.5 inches from the 8s. Anyone running this setup?

All depends on what ride height you are at and the state of your suspension. Ask yourself some questions:

Are you running on old shocks/ suspension bits? Do you corner the car hard on these or do you take it easy?

Do you "need" 9's? Can you fit 255s on the 8s and be happy?

If you ARE going below Euro ride height (whatever that means at this point), do you feel like rolling the fenders?

All that said, I am running 9s now and would go either way if I had it to do over again. I'm using 245/40/17 tires on the 9s and haven't had any issues with rubbing at the stock '83 "Euro" ride height. YRMV. The 17" Euromiesters with tires are heavy enough that you feel the difference when accelerating which is something to think about. I would have gone with 16s if the tire selection were better, but this is the world we live in.

Good luck.

Steve- That's what I'm really afraid of also going with cast wheels....hearing that you can tell with acceleration is definitely a factor to consider......current setup is 83 BBS RS 16s....forged and light. I really want to be able to throw some Michelin Super sports on, but with the 16s...no go

Have you seen the Euromeisters in person? They had one feature I wasnt really fond of and that is the lip of the wheel has very lightly machined ridges to give them the anodized look. I ended up getting rid of them in favor of the real thing after a few months.

9"x17"ET15 with 255/40-17 will fit all SC and Carreras with no problems, even on below Euro ride height.
I'm running 9"x17"ET16 and 255/40-17 with 25mm spacers on my lowered narrow body Carrera...

I have the following with no rubbing

F: 205/55/16 (7”)
R: 245/45/16 (9”)

[RR711]

I have a pair of 8's and also of 9's. If you have access to both sizes or can view good pictures of both you will see that the added width of the 9's must be on the inside because with the exception of the valve stem placement they appear virtually identical. If the wider appearance of a 9" wheel over that of an 8" is what your looking for, actually the Euromeisters will look the same.

Don't believe everything that you hear, Most people would be hard pressed to feel a 10#/wheel delta. There is a penalty for extra wheel or tire weight, more so for tire weight even more so for increased tire OD.

Far more significant is the tire OD and even more pertinent is the tire revs/mi, these specs vary quite a bit for tires of the same nominal size but on average
225/50 x16 revs/mi is ~839
245/40 x17 revs/mi is ~842 less than 1% better acceleration
255/40 x17 revs/mi is ~834 ~ 1% worse acceleration than 225/50 x16

225/50 x16 & 245/40 x17 will fit fine on an SC w/ 8ET10.6 wheels
255/40 x17 fits fine on an SC w/ 9ET15 wheels

205/40, 205/45, 215/45 x17 all will fit fine on 7Et23.3

for best performance most of the above want a wider wheel 7.5 or 8 in front and 9.5 in back

This is true. I had mine hydro-blasted to get rid of the ridges.

Just sharing what I observed Bill. The tires are slightly heavier when you go from 16s to 17s. The wheels are slightly heavier going from Fuchs to Euromiesters. The difference in acceleration wasn't Earth shattering, by any means, just a bit different and more than I was expecting.


OP do what you want. You won't be disappointed with either the 8 or 9 inch wheel as they look the same from outside the car, and in my humble opinion, they look pretty good on the car.

Great input! I think if I have my choice and they fit no problem on the euro height/minus setup I would definitely want to go with the 9s and put on the 255/40x17s

[dynosoar1]

After just finishing the turbo tie rod upgrade and now with all this talk on the wheels....I am definitely just going to bite the bullet and refresh the whole suspension.....new inserts, bushings, ball joints, torsion bars.... the whole lot....man this rabbit hole is crazy! Thanks for all the input on this guys....keep it coming if you have other suggestions you think would be good.

I use 225/45 & 255/40 x17 on 8 & 9.5, that's a great combination especially w/ a little more motor, still ok down to a 3 liter, though the 245/40 gives a little more zip and doesn't give up much grip. on 7 & 8 x17 w/ smaller motor I'd probably go w/ 205/45 & 245/40 RE71.

On an SC/Carrera that's just not credible, you must have 930 body work

Seriously!!? This seems way too wide.....I ran the numbers and the distance from my outer hub to the fender lip is 4.125 inches measured horizontally.....with your setup it would seems like the outside of the tire would sit 6 inches out from the hub!

Not for a wide body... The main point is that there is no rubbing.

That makes way more sense! Great look! Thanks for the pictures

Amazing what a $9 spray paint can will do. The center and lug nut were black

Front 7x17 Et 23 (16.5 Lb), 80mm spacer/adapter combo with 205/50 R17

Rear 9x17 Et 15 (18 Lb), 70mm spacer/adpter combo with 255/40 R17

The tire were the same on my Cup wheel so no change size wise
