If you're looking for a non-reclinable race seat then Corbeau, Sparco and Recaro all make great seats. When it comes to recliable, Sparco and Recaro both hold your ass well but I felt I had a bit too much room side to side in the shoulders. I did sit in a Bride reclineable and it fit like a glove. Now not sure if it's worth the $800 price tag for that but just thought I'd share.
"The 300ZX Turbo is a dance; it's a song; it's rolling, roaring automotive art. There is no color that doesn't suit it. There is no mood-lifting chemical substance it can't replace." - Automobile Magazine
