How much can you compensate for shorter drivers? Say 5'2" ish. How would you solve for have two people a foot apart in height use the same seat?

gmgracing

What are you mostly concerned about? Leg length or the height of the seat? (not being able to see over the steering wheel)

The base kit will definitely have enough movement forward and back for someone 5'2" and 6'2", but if the taller person wants the seat mounted low to head clearance, the shorts drive may have visibility issues. I would set the seat at the middle height on the sidemounts.

Not being able to see over the steering wheel would be the concern in this case. I don't have experience with aftermarket seats such as this to know how easy they are to adjust for such things. The LWB's at least have the height adjustment function. I like my seating position very low, she like to be quite a bit higher.

gmgracing

Unfortunately to adjust height you would have to remove the seat. Maybe you two can compromise on the height and find a happy medium

Would it fit the std LWB seat?

It would be good to be able to get different adjustments on it.

gmgracing

no, the factory LWB has its own system. It also has motors that electronically adjust height

Maxi_z

Sorry maybe the LWB it s the latest one as fitted on the RS.

I was meaning the reclinable gt2 bucket that can t be adjusted at all.

When using a aftermarket seat and bracket are there any issues with all the wiring being disconnected, alarms or other?

Alan C.

As long as you don't turn the key on there shouldn't be any issues. I've done it several times without issue.

jlanka

Alan, that's assuming the aftermarket seat has a wiring harness that can be plugged in. I kind of doubt that's the case

You need to remove the occupancy sensor and move it into the new seat, along with a box thats attached to the bottom of the seat. Then you need to add some resistors to look like airbags.

My fault for misreading the post. Only applies to a stock seat. Aftermarket and you get a code.
