Recommended 18” Square Setup – BMW F8X M3 / M4
This 18x10 ET25 square setup is a popular choice for enthusiasts looking to reduce understeer, improve front-end grip, and allow front-to-rear tire rotation.
Compared to staggered setups, this configuration offers better balance, but may slightly reduce rear-end traction under heavy acceleration.

Fitment Notes
