update.
iv yet to get back to the place i bought my compressor with the info i was asked to get.
im now thinking in regards to the low ride height it might be riding on just the springs and the dampers are doing dilly squat. my reasoning, i was giving it some shoe along the outer ring road and there is a point where the road goes down and then rises with a long right hand bend before going to a sweeping left before leveling and the car didnt feel very stable, it almost felt woolly.
now i know the car has been lowered and if been looking at how to diagnose work dampers and most of what they say to check, i cant do like bounce the car, it feels solid (no give), it doesnt lean as much cos of the lowered ride height.
