18x11.0 square set on F8X M3/M4 is not a direct fit on the standard suspension and bodywork. Unless you have our full GTMore suspension and wheel package.... This setup will let you run 305 or 315* slick tires at all four corners.

Unless you are building custom forged wheels, the selection of 18x11 wheels is limited. The goal is a combined wheel+spacer offset as close to -2 to -7mm offset. We have run with 11.0" ET44 (the most common off-the-shelf), ET30, ET25, and others. We will have a new 11.0" wheel spec in the near future.

All non-custom wheels will require a spacer to achieve an optimum offset and wheel placement. The size of the spacer will depend on your tire choice - tires can be physically different dimensions than advertised.

Fitment of any of these wheels requires our full GTMore coil over and control arm suspension package. This package was developed from our GTMore project car - making a standard production M4 faster than our GT4 race cars. BMW Motorsport was able to stuff 18x11 305 slick tires at all four corners but - as we found over a year of work - it's not so simple. We could have sold the Genuine Motorsport GT4 parts - or straight up copied them - but after racing the GT4 for several seasons we saw potential for improvement. The GTMore suspension is custom-made for this application and not shared with any other BMW model or package.

* Tires - if you buy slick tires you already know that the actual dimensions vary by manufacturer and model. And tire models change often. We experimented with multiple different tires during GTMore development with 305 being an easy fit and 315 being a "comfortable fit" but may be tight through the whole steering range. The GT4 ran with spec 305 tires. Look closely at the dimensions and if a 315 is on the larger end of the scale you may have some rubbing to contend with.

Default wheel color is Black. However, some wheels may be available in other colors. Please inquire.

About GTMore
We raced the F82 M4 GT4 in IMSA and SRO series for six years, achieving multiple wins and podiums. But the GT4 was a homologated model - tightly regulated by the series to balance performance with its competitors. In the interest of parity they gave the M4 generous brakes and tire sizes but reigned in the horsepower - rules limited it to five power levels with the highest being 500 crank hp. Innovation and curiosity is in our DNA so we wondered: "How much more performance is left in the GT4 platform if we removed the series restrictions? Can we build a street M4 with more speed than the GT4?" And the GTMore idea was born... Click here for the full GTMore build.
