Seat position / distance question

[Mobileadam]

Hi,

I've been an e70 owner for a couple of years but always struggled with seat position. It just feels like my seat is not straight but who knows!!! Which leans to minor pain / discomfort.

Anyway, my question is how far do people sit from the front dash? For example how many fists can you fit between your left knee (uk drivers) and the actual dashboard? I'm 5ft 10 and medium build but with poor posture! I've tried sitting so my knee is almost touching the dash (no joy) this week I'm trying 3 to 4 fists but I feel a long way back from front.

I'm just really interested in people's preferences as I've tried for so long to get comfortable and failed (typically get soreness / pain down my right hand side).

Thanks for any comments
