I recently started autocrossing my car, and the only complaint I have is my helmet is contacting my roof. I'm 6'1" and have the GRP Carbon roof, which does have cutouts for clearance. Unfortunately, the tip of my helmet still contacts the roof, but just barely. Currently, I have probax seats with schroth 4 pt ASM harnesses. I was looking at swapping in the inokinetic Tall Rails to buy myself some room, but I'm wondering if this would be problematic with the harness cutouts in the seat. Does anyone have experience with this? Is there a better solution?
