Options to be Considered:

Backrest Rising kit

Lowering the seat, naturally the backrest would need to be raised to match a tall driver body structure - with the head rest, side supports, speakers, belt guides. What it does is to raise the ergonomics of the backrest to where is it meant to be and work, as those seats are compromised for all heights of drivers. More info is available here. 

Fine drop adjustment kit

After customers feedback and request we now offer a Fine Drop Adjustment kit, allowing graduate lowering to the 48mm. You can vary the drop gradually from 33mm (1.3") to 48mm in 5mm steps. This corresponds to drops of 33, 38, 43 and 48mm. It consists of six aluminum shims to be exactly alligned under the adapter rails and are strongly recommended for drivers below 1850cm (6'08"). It also allows to better adjust the car between partners. Please consult the table below for more details.
