hi
well i was looking at the vw electronic parts catalouge and noted a few things . over the years vw used 19 22 and 24 mm tall pistons all in a 16mm diameter some with grooves some without. all pistons where available in oversize formats of 16.5 mm as well so right from the early days this has been a problem.

i have a late typ4 hydro case with only one piston up front by the oil pump so i dont think there is anykit comercialy available for that streaching the spring may give me more pressure but im thinking of buying a compression spring with an outside diameter of 12/13 mm that will fit inside the existing spring.

i need to take out whats in there and have a good look at it i should imagine that a 2mm taller piston with a stock spring would give improvement ?

be good
