ZT Passenger seat height -Up>
I intend to do this in the hope it stops the annoying "buzz" from my left when driving. Two lengths of 50mm-h x 40mm-w mild steel section to be inserted between the existing runners and the car floor. Longer bolts to deal with the extra height. I may want/need to have sections of tubular steel to be inside the 50mmsection for the bolts to go through and as a strengthener. Can anyone help me with correct description of the fastening bolts? I know they will be 50mm longer than the existing ones. I will endevour to take photo's and post them on the site. Chris.S.

As this is a "modification", you will need to inform your insurers surerly.

Unlikely- modification is a weasel word. I have now removed the seat bolts. They are likely to be a "modification" of MGRovers own!!! as they are Torx type and not Ribe 8, as has been talked of on this site. So did MGR used some of one type and some of the other type? Any way they were removed with the Ribe 8 bit. Another glitch - steel box section does not come in 50x40mm so I have to go with 40x40mm. Chris.S.

I thought of doing something similar but was put off by the safety aspect/insurance/passenger liability aspects in the event of an accident. Tensile strength of longer bolts, non standard seat base etc.
I am sure it would work fine in normal use but in a serious accident scenario where the passenger seat broke free with serious injury resulting I wouldn't want to risk a claim for damages when the insurers walk away.

Thanks to you both I will in due course set out what I may have done-most things calculable. Having the spacers drilled and will then see how its panning out. The captive bolts are in good condition Im pleased about. Chris.S.

I would be worried about the stress put onto longer bolts in the event of a accident. To keep the same shear strength the bold should also increase in thickness as it gets longer. The throught of the seat base complete wth seat belt mounts etc tearing off the floor in an accident just doesn't bear thinking about. What mine really needs is a conversion that uses a seat base from a left hand drive car with the electric seat adjustments. That conversion has also been done! Having said that, in the event of an accident the insurance still wouldn't pay out if they got wind of any "home brewed " conversion, no matter how safe you made it.

There was a thread a while back on seats where it was said that height adjusting passenger seats were offered as an option which I'd never heard of before nor have I seen any offered for sale.
I am fighting off having to let the 75 go in preference for something a bit higher off the ground. Just wish I still had a nice dry garage where I could tuck it away.

That or buy a drivers seat from a lhd car.
But in any case, an 8.8 grade m10 fastener had a minimum ultimate tensile strength of over 5000kgf. You would be more likely to pull the threaded insert out of the floor as opposed to shearing a fastener. And if you were in an accident with sufficient force to do either of those it would almost certainly be fatal due to deceleration forces. So crack on, a couple of spacers won’t adversely affect the safety of the standard fitted items. A full runner length of 50mm x 25mm square hollow section would be a neater job over four spacers And you could use any fastener really, a hexagon headed bolt may not fit but a cap head or Allen headed bolt should be fine if you can’t find any suitable length torx headed bolts

One thing that may get questioned but should not be relevant, would.be the airbag (this should be designed to be effective for the heights of people rather than the height of the seat). Sent from my SM-A600FN using Tapatalk
