3000M Seat height

[youngnick1]

Having now cleaned the seats of 30 years accumulated crud and managed to get all the mechanisms working, I'm in a position to replace the seats on my 3000M!

Accepting that it is possible to vary the height of the original seat, has anyone an idea what the front/rear distance between floor and base of runner was at the mounting points?

Is there a recommended clearance for a 6ft occupant?

Hi Youngnick, I presume that the car is the late seat version.... you need to fit the mininum so that the runner system still works and the seat is level (1x 10mm inboard and 10-20mm out board) to stop the back clashing with the upright post to the rear of the door.
The factory used hardwood packers, and the minimum would be 2 x 10mm pieces (1 on each runner)so that the locking nuts on the runner/floor bolts were not touching the floor, BUT you will find the floor is canted over and require 10mm plus to level the seat out, OR you will suffer from a bad back!

Thanks Adrian - as I suspected but it is always useful to take the guess work out, it saves a lot of experimentation. I assume the clearance was the same front to back.

Hi You have to space to the thickness of the lock nuts of the bolt through the runner as the minimum..or you could weld the mounting bolt through and add a mudguard washer under the runner (as the griffith/chimaera). The seat frame (no sharp edges) and foam is a thing of comfort, the safety issues is the mount points for the seat belt. I'm 6ft 4ins and made a point of remounting all 51...soon to be 52 of the TVR's seats so I can fit...also I have had the same pedal box in 20 odd of those cars!
