Aftermarket Seats in 240Z

[z-ya]

I'm in the process of upgrading my seats for track and autocross. I picked up some Corbeau GT7 seats, but they sit up way to high. Have people cut out the factory seat mounts, and just bolted the new seat rails throught the floor? I have real solid floors (Zedfindings Kit). Can I just bolt them through the floor, or should I weld some studs in?

Please post comments and or suggestions.

Thanks,

Please don't cut out the seat-mount members - they are an integral part of the shell and cutting them out will make your bodyshell weaker.

I don't know about the USA, but for just about any race / rally / autoX series here in the UK you would not be allowed past scrutineering with seats just bolted to the floor. You'd be amazed how much this would tear up your floor - especially with a bit of spirited high-G driving, and the safety issues in the event of an accident don't bear thinking about.

The best thing to do is to lower the stock seat members by cutting and shutting them. You might want to take the time to gusset them at the points where they join the trans tunnel and the inside of the sill ( rocker panel to you ).

I had Corbeau GT8 buckets in my previous car ( a 73 model ) and had to lower the seat members to get a proper driving position. The Corbeaus, like a lot of aftermarket seats, have quite a thick seat base - which causes you to be sitting quite high if you still use the stock sliders. Even if you bolt the seat direct to the seat members it still leaves them quite high.

Cut and shut the seat crossmembers properly and be done with it.

Do it properly and be safe.

Good luck,

I've got them in there.

The passenger seat I installed to the stock seat supports. The seating position is a little high for me (6'2"), but I can still sit in the passenger seat without me head touching the headliner (real close).

On the driver side I made new seat supports that are about 2" shorter than stock. The rear ones are practically sitting on the floor, where the front one sits about 2" off the floor. Gives me plenty of head room for a helmet, and I like stting low in a sports car anyway.

Once I get the interior back together, and my wiring straightened out (had to remove an amp that I had under the driver's seat). I'll post some pics. No project is easy at this point...
