hey. just got my s13 yesterday after my mx-6 disaster.... i need new rear struts ( or shocks- whats the difference?) but when i went to go check on them they asked if i had the automatic leveling system. what does it do and how do i check for it? and i dont have a manual.... and i needed new brake pads n they asked if i had abs... not sure ifi have that either. so i was jus gonna go out n hit about 40 mph n hit the brakes n see if i slide or not... haha, oh well... also if yall know any good spots around l'ville/buford to learn driftin or know where a track is nearby that would be helpful... oh n how do i check to see if my springs are adjustable... the car came lowered 2 inches but it doesnt look like the rear is sitting any lower- looks kinda weird... will new shocks make it sit lower? thanks.
