Wobbly Seats

[nelmo]

I've got Intatrim seats on universal runners but they're quite wobbly. I think this is because they are effectively sitting on the 4 nuts that go through the floor, rather than being flat to the floor, if that makes sense.

 

What I mean is, after fixing the runners to the seats, I put a bolt through the runner with a nut to tighten it against the runner. Then that bolt goes through the floor to the final nut and washer underneath.

 

If I don't have that nut, I can't tighten the nut underneath but that nut is, i think, causing the wobble.

 

Is this normal? Have I got this right or am I doing something wrong?

The floor needs proper reinforceing where the bolts go through the floor.

I have 1inch angle iron spreading the load.

I have a bolt through the runner clamped with a nut then a second nut to a penny washer and through the floor to the angle iron where it has a further nut to clamp the angle firmly.

The 2 nuts either side of the floor allow some adjustment to get the seat level.

The angle iron is further bolted to the floor in several places spreading the load.

Thanks guys - so do your seats still wobble a bit or are they rock solid?

+ just noticed from your blog picture

 

Put the washers next to the floorpan - i.e. on the inside of the car that nyloc is just to give clearance and stop the bolt falling out during installation - the penny washer needs to be next to the floor rather than next to the runner.

Arrgh, you're right! Why didn't I realise? Many thanks... and I'll get those bigger washers.

my seats are about as stable as Richard describes
