I have a Corbeau CR1 racing seat, 2" double release harness belt, and a seat slider. All of it is in great condition. The seat and harness is blue. The slider works great. You will need to make a seat bracket or buy one. This one has one that will fit E30 BMWs. The retail on all of this is 590 not including any taxes or shipping you might pay on this kind of bulky stuff.
Sure send me a pm when you get home and I will send you my number. Corbeau says it weighs 27lbs. It feels lighter.
I’m a fairly stocky guy, I can fit in it but barely. I have broad shoulders etc. I’m about 210. Id say it would better fit someone of a “normal” build. I’m wide. That’s why I’m not using the seat.
