Hey guys, I have a genuine red leather fixed back lightweight Sparco racing seat, actually I have 2. 1 is in good condition and one is in horrible condition.

Im looking to strip the crap one back to a fibreglass shell, and then mould it to my exact shape.

I was thinking of glueing that blue high density styrofoam to it, the sandable stuff, then sanding it to my exact shape, followed by a 3 or 5 mm layer of that rubbery foam stuff over the top to pad it a little, and then either just a thin flexible seat cover, or glue some wetsuit style material over it (or something stretchy and similar).

Anyone done anything similar, or know how the pros do it?

Thanks,
Dann

Hi Dann,
Styrofoam will distort and form under your body weight, think of helmet liners. Compatible glues are an issue too because foam doesn't like everything. There is a bloke in here somewhere who is familiar with fibreglass.
Good luck.
Greg.

you can get a 2 part foam that when you mix together will go off and mould to your body shape

its messy, but works a treat. Ive made a few seats for myself for various open wheelers

Ive seen that. you put it in a garbage bag right?
how do you then cover it so it looks nice?

An example of kits you can buy: http://www.demon-tweeks.co.uk/Motorspor ... _Kits/3602

Not sure if you can buy anything like it here or not?

In a race car most people just cover the thing in duct tape and be done with it but there is nothing to stop you covering it in whatever you like really as long as the glue is not going to melt the foam.

I would definitely look to go this route though, sanding a foam block down would be seriously time consuming and messy.

Yep thats the answer.

Ill buy one. Im just afraid that it will be hard to cover and mould perfectly as the bag will be all embedded inside the foam.

Just make sure you're not alone if/when you do this or a phone is within reach, many a story floating around the net of guys doing this alone and becoming trapped after mixing up to much foam.

Hahaha! I'd love to be around just to see it happen! I'll help once I've stopped laughing and changed my pants of course...

Just what do you have in mind for Dann once he becomes trapped in his seat
