I'd like to introduce Cipher Racing Seats. 2 years ago I purchased a set of their seats and custom brackets for myself and was so impressed I decided to become a dealer rep for them.
Previously I had their 1013 series installed in my Monte. They are $399 Delivered anywhere in the U.S. I used their custom brackets to bolt them into place. The fit, finish and comfort is amazing. I've driven over 400 highway miles in them with no "crap! my butt/back are sore" thoughts when I exit the car. They are firm, but comfortable.
I have upgraded to their 2004 E-8 Seats and for a little different style. Again, great seats, extremely comfortable and capable for the track.
Cipher has a full line up of seats that I offer. Have a look at them all here:
