Fibreglass race seat

[Eibar]

Just got a fibreglass seat for the sprinter but interested to hear how others may have fitted theirs.

My Initial thought was to put a steel reinforcing plate underneath seat running down its length and drill 4 holes for countersunk hexhead bolts resting on a number of nylon washers to protect the body.

Unless you have a better thought out way of mounting.

Cheers.

Eibar, I can't speak from experience yet but I'll be doing this too in a few weeks. I was going to use 4 socket head flange button screws, maybe with repair washers to spread the load on the fibreglass, and nylon washers between the seat and the frame. I'll be putting a 2.5mm racing foam on top as a seat.

I was working on the basis that the fibreglass would be strong enough to cope with my ample weight without any further metal plate but I can see where you're coming from.

I love the word flange it's nearly as good as gusset and neither are used enough

hi

i`ve just done one :-

1. Cut two plates about 125mm square out of 1mm mild steel and drilled a 9mm hole in each corner matching the four holes in the frame behind the petrol tank hole - the mounting position
one plate for the top and one for the bottom (plate/seat/plate) to stop the fibreglass been damaged when finished and bolted up and for the fixing bolts - see item 3 below

2. Ground the heads down on four m8 bolts which where long enough to go through seat and frame to bolt up - ground them down so i could keep the padding as thin as possible and the bolts would nt be felt on my boney arse.

3. Put the bolts throught the plates/seat/plate and a nut on the underside - once it was all lined up on the frame it was nipped up and the bolts welded to the top plate

4. Remove the nuts and replace them with a hard rubber washer to protect the frame/paint

5. painted the plates then covered it

hey presto finished - now i just need a new rack

hope all that makes sense without photos

best of luck

Thanks for the answers people, metal plates have been cut and I think I'll go with the buttonheads option topped off with some high density foam.

i take it your using the standard loop? mines going to be fitted to two bars extending up from the frame ( no loop ),going to have several holes for fitment to get the seating right so it can be adjusted as nec, i'm using the old TZ type (cheers Ricspeed ), i will put a small square plate undrneath to spread the load.

Done , Crude but effective
