fitting pro series, sprint, i have sparco sidemounts but no subframes? i asumed that you removed seats, bolt side mounts to floor then to seats but mate said i need to buy subframes aswell, due to angle of floor? was wondering can i just buy some subframes for my 172 on yb racing, there omp ones? or will i have trouble mounting the omp sub frames to the spaco side mounts please help?

I take it you have buckets which can be side mounted?

In which case, you bolt the side mounts to the floor and then you can adjust the angle of the seats with the different holes on the side mounts.

Just make sure you mount the side mounts in the right place.

Bolt them to your seats and then loosely put them in you car... sit in to find out where you want them ie... being able to operate the pedals!!!

If your bolting them directly to the floor use a plate under the car and bolt to this extra support if they worse were to happen.

I usually weld two bars inside the car and mount the seats direclty to them via the sidemounts.

However... omp do a simple Mounting plate which bolts to the OEM seat mounting pos... you then bolt the sidemounts to this and your away.
I think they are about £170ish...

ok lads understand kind of just wondered how it sits straight because you know the subframes on a clio arnt parelel one if further back than the other? so just the seats and side mounts should be fine then? and also mind telling me the bolts i need ie to the floor and any idea the bolts into the seats from the side mount?

That was basically thrown in, usually i cut the OEM seat mounting points out "drill the spot welds out" and reweld in two bars.

Bolts whatever size hole you drill and make sure you use washer both sides, i think the sidemount to seat bolts are M6 or M8 im not 100% sure my cobra ones are M8 x1.25

ok understand mate didnt really want to wels, so am just going to sacrafice 110 on yb racing and buy 2 clio subframes then bolt my sparco side mounts to the subframes, should work correct guys?

 

[rexe]

yup. w17gle did that and had no problems at all.

 

[stacky]

o right ok hope all holes line up should be a problem side mounts like unerversal?

 

[stacky]

also these the right ones hc/779/d and hc/779/s yb racing subframes? HC/779/D
HC/779/D

 

[Greeny.]

They 'look' right stacky, I will need to get myself some of these as well when I get my new seats! Should be nice and low with these

 

[stacky]

lol hope now to low ? lol thats the good thing about side mounts height choice agree?

Bolting to floor = not good. Should go check the proper MSA/FIA approved method. Basically weld in two metal bars between sill and exhaust tunnel onto which you can mount the side mounts.

The forces in an accident can be massive and a few bolts through a thin gauge floor won't be enough to keep you in place.
