Aftermarket 19 inch wheels for CCBs

Hello,


I have 2017 M3 competition pack with of course the 666s. Iam preparing my car for the track.

I have purchased the Bilstein B16 damptronic kit which is on the way. This kit is height adjustable if you don't know and I am looking to get the car as low as I can without having a wheel clearance issue. For the track, 19 inch tyres will be cheaper too.

I want some lightweight aftermarket rims, but of course they need to clear the carbon ceramic brake kit.

Anyone running aftermarket 19s with CCB's? If so, which ones?

I was looking at Inspiri FFR6 which are approx 22-23lbs per rim but they won't send me a rim out for trial on the front.


Ats.

here is the wheel on their website, on an M4 GTS which has the same CCB. Should be fine. the company should be able to figure this out for you though, or at least send you the exact measurements of the wheel you can post up here.

The thing is, the M4 on the website has 20s on it. I want 19s. That's the issue.

The company said that they don't think it will fit as factory 437m wheel is fully forged with a thinner barrel wall than their 19 inch FFR6. But they haven't actually tested to see. Their staff members had told me different things and that is why I want to trial for myself.

Can someone be kind enough to tell me to the millimetre, the internal diameter (from barrel wall to barrel wall) of a 437m wheel that might be stored in your garage.

I will run that measurement past them to see if its, the same/smaller/bigger.

Thank you.

^ he needs the specs on the inner barrel diameter. not the overall diameter. otherwise the caliper hits the wheel.

like what happened to this guy:

Exactly this.

And thanks directing me to that thread which is exactly the problem I have!
The thing is for BBS forged, It will cost 5-6k but the Inspiri are 1200 and are very light light too. That's what dictated my choice. I'd go for fully custom with if money wasn't an issue.
