Steermaster round and flat bottom comparison using current product data.
Steermaster flat bottom wheels are positioned as a more performance-styled upgrade. The product data also notes 30 mm more knee clearance during entry and exit for the flat bottom silver variant.
Round wheels preserve the original BMW-style profile and will feel more familiar to owners who want to keep the standard steering geometry while improving materials, stitching, and finish.
Choose flat bottom if the goal is a more performance-led cabin feel and a more distinctive visual change. Choose round if you want the most factory-like steering shape with upgraded leather and finish.
No separate installation process is published. Both are presented as part of the same 2-3 hour professional installation flow.
In Steermaster product data, both the flat bottom and round leather options are listed for F30, F80, G20, and G80 fitment.
