Lots of info in this thread

Definitive JCW Brake Clearance and Wheel Fitment Thread

I've searched the forum and we only have bits an bobs of information of info regarding fitting wheels over the JCW Brembo brakes. Pictures are also super important too (I'll share as I go along). I'm not talking 'good enough' fit here, the fit needs to be perfect and not poke beyond arches or...

@Fivetones thanks, really appreciate it!

 

I run OZ 18x8 et45 with 225/40 tyres and unless your car is lowered you should not have any problems.

 

Thanks! It’s lowered on MSS springs. Looking at adjusting the camper a bit, but the challenge is getting accurate details of tyre sizes because they all appear to be slightly different in actual width. Got about 5mm between rim and strut with a wheel and no tyre fitted.

 

Mines is lowered with the AC Schnitzer lowering springs so have opted for 215/40/18. I think it's a 20mm drop. Also went for the 215 so the speed error won't be too much.

 

Looks great!! This is the drop on mine, with 20mm spacers.

 

Here's some better close up pics of my wheel and tyre set up. Now with fresh brake discs and pads to complete the look 😎

 

So clean!! I prefer your matt black look, unfortunately the rims I bought only come in gloss black. May have to consider a respray before getting them on!
Are yours 8.5”? That must be close to the strut?

 

My OZ Ultraleggera wheels is 8x18 ET45. Didn't your first post specified your wheels 8j and not 8.5j?

If it is indeed 8.5x18 ET45, then perhaps 8j width tyres would still fit albeit a stretch set up.

Here's a useful online calculator to work out the new set up:

It was your Will They Fit comparisons above that threw me, you've compared a 6" rim against an 8.5" rim. The wheels I have on are 7" on 205/40s, new wheels are 8" and I'd like to get 225/40s on. I've used Will They Fit, but it doesn't tell me what the actual clearance will be...unfortunately.

 

I have SSR GTV02 18x8 ET45 imported from Japan with 225/40 Pilot Sport 4, and it's been riding very well. It is also lowered with Eibach springs, however, forgot lowered by how much mm. It does clear the Brembo caliper much more than the standard JCW rims. I do hear a slight rubbing in the wheel arch at the rear. However, only when the car is packed and going over big bumps.

Hope this helps!

They are nice looking wheels!
That’s really useful feedback, thank you.
Are your tyres the 4 or 4S and do you know where in the arch they are rubbing?
Been trying to find somewhere that shows actually tyre measurements, rather than what the manufacturer claims. Being spoilt for choice doesn’t always make it easy!

 

There’s also the new PS5 (I have the 205/40 18). Grips well so far and supposedly has better wear characteristics (and a slightly lovelier velvet side wall). My car is the SE so didn’t mind a more efficient, slightly harder compound in the name of efficiency. No PS4S in 205 or 215 either in the UK I don’t think (only 225).

 

Completely forgot about the new PS5! Thank you for your information. Yes, I will consider that next time I need a tire change.

I am lowered and dont think 225 will fit.

Nice looking car!
My wheels are ET45, so 3mm further in than yours. Where do you think the clearance issue will be?

 

I am running 225s on 18x8 ET44 and no rubbing.

 

stock height or lowered?
