If the lower front retaining screws are not in place then on the freeway the wheel well lining is pushed back by the force of the wind against the tyre, this causes the tyre to eat away the lining. Replaced many over the years for this exact reason.
Some real OCD there Peter great work! :clapper:
Is the duct coming in at the fender liner some sort of brake cooling thing?
This would at least make it a lot better that the Z4M where all the air goes straight onto the centre of the tire... :skit:
In closing I drove the car some 200Kms back to its owner and what has particularly impressed me is the manner in which the engine delivers its power.
The torque is constant and although lower than its s50b32 and s54 siblings a lot more usable.
I cruised at 4000rpm in 5th gear and (7.8L/100Km indicated) and not once did I need to change down to fourth to overtake.
I think I get it now when enthusiasts speak with great affection about the s50b30.
Its great when you refer someone and they can't thank you enough. Thanks peter for a job well done and bringing back faith and honesty in an industry where standards have all but disappeared:ty:
