Seat load spreader recommendations
vinny1275 - 21/2/09 at 05:44 PM

Hi all,

I was wondering what thickness & size load spreader to use under the floor of the car for mounting the seats onto. Also, does it need a spreader above and below the floor?

Thanks,


Vince

What floor is it? Alloy or steel? I was planning on using some very large penny washers on my alloy floor but in the end used a bar of 30mm wide 1.5mm thick ali between the bolts.

Normally you just need a spreader below...

Depends what the floor's made of. Mine is steel and I used huge washers (about 2.5" on the underneath only

did you fit the bar front to back, or side to side?

Hi

To answer your question you need to consider where the loads are being experienced. In the case of a seat most of the loading will be downwards and therefore the load spreading needs to be on the upper surface of the floor. In the event of a 'rear ender' or under acceleration the seat may try to tilt backwards and therefore some load spreading under the floor at the front attachments is advantageous. Cornering may impose upward loads on the mounts but the loads will be less than the previous examples and spreading can be adjusted to suit.
