I was reading up on SCC's Project Nissan Silvia and remembered that the floor of the 240SX is shaped funny, with an intrusion into the cabin under the driver's right knee. I was wondering what was under said hump to make it so large. Thanks for any answers.

 

i think thats about where the cat is isnt it?

and doesnt scc's car sound like it would be a blast to drive?
ive been following the story on it from day one.

 

i know there is a hump on my floor board, its just for the tranny.

 

If that's where the cat is, can't I just relocate the cat a little further back so I can fit "normal" seats in? I don't want JIC seats, and I don't want to spend a fortune on R32 seats that weigh a ton. I want to put a Sparco Evo in there, but apparently it'd be impossible according to SCC.
P.S.- Yes, it does sound like it would be a blast to drive.

 

The thing with the hump, is that if you have sliding brackets, it will be too high. I wabt to take soem old stock seats, and see it i can use the stock brackets, and bolt it to the sides of a bucket, making a seat that is solid mountedd, but sitting on the floor. I might try that someday...

 

I think you are kind of stuck with the hump.

 

lol....hump....lol

 

I'll have to look for pictures. There has got to be a way to mount seats made by someone other than JIC, Bride, or Nismo in a 240SX.

 

Don't S14 seats bolt up directly?
I am not sure, but I think I remember seeing someone do this.
Does anyone know for sure?

 

yea, S14 seats are a great upgrade

 

Regular S14 seats?

 

Yea, the front seats of a S14 fit

 

that's actually probably the most popular seat upgrade for the 240.

you're big companies are gonna have custom made brackets for the 240 and similar nissans. corbeau makes one, i believe sparco does as well

 

I am 6 foot tall have drive cars with the Sparco Rev and a Helmet on.

You don't need the JIC seats. You need low down rails.

 

Can you expand on this - which rails did you use?

My '90 is going to eventually be built to NASA and SCCA club specs and I would really like to find out the best way to get my butt as low as possible given the cat hump. Alternatively I will be looking into cutting out the hump and welding a plate in since it will be a catless system.

Any response on getting solid backed competition seats as low as possible will be greatly appreciated - explanations and pix doubly so.
