M4 GT4 wheels - 18x11 ET30, 20.3lb?

Significantly pricier than some of the other offerings, but the rear would just bolt on with no spacers and the front would need less spacer than the ET44-ish F8x fitments

That's a 305 slick I believe, square, on that car, and it obviously has a ton of camber just like an E9x needs for 18x11's. Anybody tried them on our cars? Not a bad option for, say, an STU autocross build either

thats hot as F. price isn't terrible, either.

take note of the f80 brake duct (i presume) inlets above the side inlets.

I'm tempted now

Is there something about the setup you are referring to that makes it better for autocross than say a typical track? Thanks

Interesting option, but getting them (or replacements) could be a big hassle:


This is a part that we buy directly from BMW Motorsport. It was originally designed by Motorsport engineers for competition use in a factory BMW racing program. As a part desgined for competition use, it does not have a warranty. BMW Motorsport parts may sometimes be in short supply and orders are released at the discretion of BMW Motorsport. If a part is not in stock, contact us for the latest estimate on delivery time.


I guess if you're not in a hurry, or maybe even order some spares, it's fine. But at a certain point I'd almost rather get something like Forgelines built to my exact spec, color, etc. Plus, you can get them fixed or replaced more easily.

I have a set of them and run them on my car along with a set of Titan7 wheels in 18x10.5 et25. You can run them square just need a spacer in the front, no spacer needed in the rear. This was before raising the car a little.

how much spacer do you need to clear the strut on the front?

[StripclubDJ]

Can we see a pick of the whole setup?

Run a 12mm spacer in the front with a 5in spring and like 4 degrees of camber.

Like the wheel fitment front and rear

Tire size and alignment specs ?

Looks like a 305/680 maybe?
And I imagine -4 camber lol

Sorry. Tire is 305/660 same tire used on the GT4 M4. Have a 5in spring to clear the perch with around 4 degrees of camber (think it's a little more). Front fender liners pulled would hit all over if still in. Think that's about it.

Rear is super easy just slap them on! Lol had not issues think I run 2 degrees in the rear.

Wheels are just the exact M4 GT4 wheel 18x11 et30

Yeah my rear is a 305/35 18x11 +30with -2 and its good to go

This guy's setup is ok...

Actually it was pretty shocking seeing it. I was like...you're putting what on the front? A 305? Had to be the fastest car at Hallett even with bad weather.

[Richbot]

305's on an 11 do you even stance bro

I bet that's a busy office at Hallett with all that front tire and 400+hp. I've only ever done Hallett in slow cars end even then it's not exactly relaxing

I Cant wait till next year that track was so much fun. If we could get some good weather that would be nice! Rain, Mist, Rain.

[Richbot]

Have you done it clockwise yet? I'm itching to get back down there for a clockwise race. I use their race shop for CSR/Spec Racer Ford help on things I can't or shouldn't do myself and their shop manager is also an extremely hot shoe so I owe him an opportunity to whip me at his home track like I did to him at mine (or he let the customer win)

sorry to bump an old thread but I found the BBS RI-A is almost identical in concavity and spec to this wheel, only difference is its an 18x10.5 +25 and the offsets are slightly different. I have also considered the Titan 7 TS5 as well in same size, maybe staggered... or square.. have not decided.

In this pic above, is that the TS5 up front?

If it is, its good to see both of these wheels on a car at the same time so I am glad I ran across this thread. Helps me make a decision. There is quite a bit a difference in price between the wheels of course but I do love the look of the GT4 wheel and the BBS RI-A seems to fit the bill. .

Anyways if you could just confirm or better yet, if you have more pics can you post them?

links to both wheels for anyone considering a similar look..

Thanks

Suspension will be the factor on running the 10.5in all around. I do have a set of the titans and they are great and fit with no spacers and for sure the best bang for your buck. Normally run the GT4 wheels when running a 315 in the back. Those BBS wheels look to be out of my budget I will try and get some pics.

[XCUSE_M3]

Pic dump sorry!
