Hi everyone do different steering wheels have there own bolt pattern for example is momo different to sass or autotecnica

There's generally two different 6 bolt stud patterns for steering wheels.

Yes they do. The two most common are 12-6 pattern bolts at 12 o'clock and 6 o'clock and 10-2 where bolts start at ten and 2 oclock. Momo, saas ,drift ,isotta, all use the 12-6 pattern and autotecnica wheels use 10-2 pattern.

Saas boss kits have bolt pcd for both types of wheel too so at least you can change your mind on wheels and don't have to get another boss
