hi i recently bought this used coil over shocks this is made of zeal either a b6 or s6 its for an ek but i installed this to my eg and it concerned of a little conversion of the rear suspension arm only.then i tested it it was not stiff at all does anyone here have reviews if its really like this?i tried putting nitrogen gas the rear improved alot with 350 psi in it but then the fronts are still playing big play.....help out gurus and masters do you have specs any input would be appreciated tnx
