I'm looking at buying some Cup 1 wheels for my 964 C4. I'm not sure what the correct offset should be. They are advertised as ET65 front and ET55 rear. Would these fit?

FlyinTomato

rear fit.

Front need 13-15mm spacers

Mikar

Thanks for that. Those spacers sound like they might be a bit much for the front?

I am sure they got the offset backwards. That is stock offset for a 993 NB, F et: 55, R et:65. Make sure you double check that they have it right before you buy.

Not backwards if this is the set being discussed (7.5" fronts, 9" rears):
Front: 965 362 124 05 7.5J X 17 - ET65
Rear: 965 362 128 00 9J X 17 - ET55

I have a set of the correct cup 1 wheels. 7 fronts and 9 rears. Correct offset. I'm not going to ask publicly what you are paying for yours, but if you really want a pair of correct cup 1s, shoot me a pm and right price right buyer, I'll consider parting with them...if you are in the states and close enough to the east coast etc.

Mine have different et than that. Sure it 57 and 43!!

Might be wrong but its around those numbers.

I have a set of these wheels, with the fronts at ET65. I got sick of using longer wheel studs and spacers and ended up buying correct offset front wheels. I think these front wheels were made for the 928.

I really like cup one's. What do a set of used ones go for?

Yea I love that wheel, seen some lately for 4+ grand a set but don't know if that's the norm.

Mixter,

How many times have you had to repaint the wheels? Powdercoated? Look good.
My need to be done... Easy to road rash the back wheels for sure.....

FWIW, my records show original Cup 1s were:

7x17 ET 55 fronts
9x17 ET 55 rears

and the Mille Miglia replica Cup 1s are:

7.5x17 ET 52 fronts
9x17 ET 47 rears

The MMs offsets supposedly look better than originals.

Hope this helps!

Yeh mine are Mille miglia replicas. That's the offset I meant to post.

TRAKCAR

OEM:

7x17 ET 55 fronts I have 2 of these
9x17 ET 55 I'd like to buy 2 of these to complete the set.

and the Mille Miglia replica Cup 1s are:

7.5x17 ET 52 fronts I have 2 of these
9x17 ET 47 rears I have 3 of these, if anyone needs one let me know. Needs to be painted (Green now)
