I won a SR20VE with 6 forward gear box.. i know its little different from the std. setup, it has stiffer shocks.. and i did check with the agents ( i personally know one guy), they accept the problem.. " all primera's has a bad roll..." but nothing they can do.. its the std sys and no mods available...
btw one of my friends own the std. car with the Auto gears and he too complains the same issue ...
do you still have the originals or have you change them locally?
