Lowering standard seats?

Post by ionofchios » Fri Feb 15, 2019 5:10 pm

I’m 6’4 and have standard manual seats in my 2006 e86. I want to move the driver’s seat down and back. Has anyone tried removing the standard runners and brackets and whatever else is under there, and replacing with fixed, maybe custom, brackets? I’m not bothered about having the seat in a fixed position. Can you get more leg and/or headroom?

It can be done, but you'd be lucky to gain an inch, as you're going to have to have some sort of base/bracket to mount them, and will have to access the mounting bolts somehow.

Be careful about making it a 'fixed' seat, as some MOT testers interpret the rules strictly, and will fail it.

Thanks. I think I’d be happy with an inch, especially height-wise. I might try taking passenger seat out, just to see what’s under there and try and work out what the bracket would need to be like.

MOT testers also can't fail the car on something that isn't fitted. If the seats are installed as fixed with no ability to move them, technically this doesn't break any regulations as there is no runners to not work.

For instance, you'd never have your MOT failed because you've installed fixed bucket seats. It is probably something to point out to a tester though, make it clear the seats are not on runners but fixed directly to the floor.

I’m in finland - never seen MOT guy check a seat over here.

Are you sure? What about a cat, or DPF, or xenon headlight washers, or windscreen wipers, bonnet, or etc.?

My tester knows my bucket seats slide as he can't get into them sliding it all the way back :P

But if it looks like a standard car seat, with buttons/switches for adjustment, and it doesn't work, then that may fall under the 'doesn't work as intended' description.

As I said, it depends on the tester's interpretation, and whether they got any the night before :P

Okay, so not quite so literal! If something is obviously missing i.e. a bonnet, thats a safety issue so of course its a fail. Headlamp washers, well arguably the tester has no way to PROVE the lights are xenon unless there's a visible ballast and wiring, so no washers isn't an issue. Washers fitted and not working is an issue.

A Cat is a legal requirement on a road car, so of course that missing is an issue. A DPF is a legal requirement on all Euro4 or newer diesels so again, an issue.

Seat runners are not a requirement. If they've been removed they are not a fail. If they're fitted and don't work, its a fail. If the OP were to completely remove the runners then its fine, regardless of there being a lever. Of course this is something you'd probably mention specifically to the tester so they don't just assume its broke.
