Will M4 Wheels fit the E89 Z4

Post by Valor1 » Wed Jun 07, 2017 3:15 am

I've been told the BMW M4 Wheels will fit the E89. I am looking at the Style 437 M wheels. They are supposed to be forged and weigh less than Z4 wheels while being wider. 9" front and 10" rear.

Has anyone fit 19" M4 wheels?

The 437M wheels?

Yes they should fit just fine, chap in Germany has them fitted, the offset is the same as the 326m so they'll extend another half inch into your wheel arch, and half an inch outwards compared to the 326 wheels.

Thank you for this very useful information! With those spacings you've described seems like it would work.....and hopefully with 275 or 285 rear tires :)

That looks interesting! I wonder if he had any rubbing issues and what size tires he used. Looks nice and aggressive and from whnat I have read these wheels are wider and lighter than the comparable z4 wheels.

Thank you! The ones I've seen discussed on the net are 9 and 10s if I recall correctly, forged and very lightweight.

Thank you! Would love to see more pics of your car. Do you know the front and rear offsets are on your wheels? 10" rear and how wide in the front? Are you running 245 in the front? Think 255 might fit?

Tirerack has BBS wheels that are 19 x 9.5 front and 10.5 rear that weigh just 16.5 front and 17.5 rear!!!! Super expensive but OMB amazing. I heard a formula that states for every one pound of rotating mass you reduce it is like taking 4 pounds of weight off the car. So if these wheels weigh a stunning 40 pounds less than OEM that would be like taking 160 pounds off the car. That's a weight difference you can really feel and measure! BBS FI-R

They are 295/30 and 235/35.

In fairness I only put the 295 on the rear as I had a spare set in the garage. I had one put on a rim to see if they would fit and "happy days"

Had i not had the tyres I would stuck with 265/275

I understand power to weight equation but why buy a E89 then get hung up on how heavy it is :? they are never going to be svelte or lithe with the roof weight + mech they are carrying :cry:
