Lowering Tilletts on a lowered floor

[heptagon]

I think there's an adjustment that you can make to lower the Tilletts a bit further.  I've already got lowered floors but would like to get seated a bit lower if possible. Does anyone know?

The solution is to recline them a little, try adding up to 30mm extra spacers between the runners and the seat at the front.

Many thanks, I thought it was something like that but wanted to be sure

Remember the more you recline them, the less you can slide them back.

I took my drivers seat out to have a look, it seems I have about 12.5mm spacer at front and 7.5mm at back - not sure if that is the standard set up?

So I think I can tilt and lower it quite a bit still? 

Can I just remove the 5mm rear spacer and raise the front or leave rear as it is and raise front? I'm running the normal adjustable seat runners.

Thanks

Leave the 2.5mm spacer in the rear and put everything else in the front, more if you need to.

Many thanks, have done that and will source a few more spacers for the front in due course to try as well

I've also removed the runners and just use the aluminium box section and reclined them as Stu says. This means the base of the Tillett is now just a few millimetres from the floor

As Chris eludes to, whatever setup you have, before bolting the seats down fully make sure that the runners are touching the floor and there's still a little clearance under the seat base, otherwise you can damage the seat when you bolt it down solid.

I've been fiddling by adding more spacers to the front, the only issue I see is that as the seat tilts, it sits less squarely on the spacers as it becomes increasingly angled, especially at the back with just a single small spacer.  Do people just ignore this or even file down the spacer a little on one side to get a better fit. 

Also can you go above 30mm at the front ok?  I'm at 30mm currently

I think the bum bulge is the limiting factor. If this is pushing against the floor it could stress the base and cause a fracture. It's almost like the floor needs a blister in the middle.

I'm not sure you'd need to go more than 30mm anyway, 25-30mm reclines the seat really well. At a guess, 30mm increase at the front must equate to a 60-90mm recline at the headrest?

I have a single Tillett 5mm (6mm?) nylon spacer at each side at the rear, it's enough to secure the seat to runners without the angle being too much of an issue. I must admit that shaving spacers front and rear to make wedges would be a more professional solution though.
