Mine is a more pedestrian F40. 1992 Euro version with adjustable suspension, uprated turbos, and a custom sports exhaust. It sports a couple of floor mats to catch grit and pebbles along with a lighter plug under the dash for the Sat Nav. Otherwise ir isThank you for the imput. It is what the specialist garage said with the porous housing. They said that the unofficial solution is to use a synthetic motorcycle fluid ( Kawazaki ? ) but I thought that all the DOT 4 fluids were synthetic anyway.
Mine is 1988 UK version with wind-up windows and non-adjustable suspension lift. It also has carpeting to absorb the noise, full Alpine stereo system with head unit mounted down by the side of the seat, multi-changer in the passenger footwell against the central tunnel and 4 speakers.......
Seats re-upholstered by the Corbeau factory with black ( protected ) sides.
My other problem area is the corrosion that manages to get under the plastic coating of the wheels. I am carrying a spare of each & get a poor example re-furbished every time that I need new tyres.
