peter are you running any droop on your hsd`s? how do you find it handles when you end a skid? mine seems to snap back into line violently which can be painful for passengers if they aren`t prepared (i nearly knocked my sister out using the window)
my hks coilovers are set with preload on the front with about 30mm of adjustment still left and the rears are maxed out with the locking ring removed and about 12mm of droop.
it hits the spare wheel well on speed bumps because the spring is too loose on the coilover but its the only way i can get the back as low as the front, the arse end of my car is completely stripped, even the spare wheel bracket has been cut out.
i was thinking about cutting the rear turrets and welding in a 30mm band so i could add preload and still have equal rideheights.
