166 Brembo Calipers

I asked about your wheels, but you did not respond?

That's a pitty, thanks for the trouble.
If they do respond, I'd realy like to know

Mine are et37 7inch

So are mine
I have two different sets, also a little bit different in design.
The heart of the rim, where the centre cap are is different.

I got myself some 8J x17 (ET 28 for front and ET 25 for rear) Compomotive wheels and it will be really interesting to make them fit under my Q4.

Do you guys know what specs of tyres are good for 8J?

I have thought about 225/45 for the rear and 215/45 at front. I'm affraid that 205/45/17 on the front wheel might be too streched for the 8J rim...

Cheers.

Hi Cristian!

I don't know it exactly, how it is for the Q4!?!

About 10 years ago I had a big problem with a 33 Permanent 4.
The viscous coupling was destroyed (got a leakage and the viscous oil was lost after permanent overheating) because of different wheel diameters on front and rear.

As far as I know the Q4 has also a viscous coupling on center diff and I think that 225/45 for the rear and 215/45 at front could maybe destroy your viscous coupling!!!

I would stay at the same wheel diameter for front and rear wheels.

I would stay at the same wheel diameter for front and rear wheels.

There's something written about in the repair manual.
You need the same diameter for the front and rear!

Guys, do you mean that I should stick to same spec for TYRES for front AND rear? For ex 215/45/17 for both axles?

Or do you mean that it's a problem if front rim has ET28 and the rear one has ET25? It's only 3mm plus for the rear...

What about those who have diffrent spacers for front and rear? Like 16mm for rear and only 5mm (or none) for the front. I'm sure I've seen here this kind of wheel fitment configuration.

Cheers,
Cristian.
