True the price is much higher but if you consider the price of your car then its not that bad...

The links cheat the car to be lower Because the sensors tell the car its too high, when you go 100mph the suspension will adapt to this, but since the systems isnt getting the correct values it doesnt do as it is supposed to..

Ive drivin with both links and module on my car now and its even lower than with the links but the car isnt near as stiff/bumby as it was with the links
