Yesterday I took my driver's seat out and reinstalled it using this mount:
I'm extremely happy with it. It got me 1-2" lower in the car, the seat is more square to the steering wheel, and in a more comfortable seating position. I had to beat the transmission tunnel with a BFH to get it to fit in the car though.
It takes some creativity to get it installed in the car, but now that it is in, it is wonderful. This might be the first time since I've had my racing seat that it is installed in the exact position that I want.
I also forgot to mention that some BFG Rivals were waiting for me on the porch when I got home yesterday. My wife dropped them off at the tire shop to be mounted this morning!
