FR-TEC Racing Enhance Kit (PS5)

I was skeptical about the concave thumb grips at first, but they really do make fine adjustments in turns feel more natural. The silicone cover also adds a nice bit of grip during longer sessions without being sticky.

The silicone cover fits snugly and adds a nice grip, making long racing sessions much more comfortable. I also noticed better stick control with the concave thumb grips right away.

Installed the silicon cover last night and it adds just enough grip without making the controller feel bulky. The concave thumb sticks took a few laps to get used to but now my cornering is noticeably more consistent.
