lewix, the original suspension shock absorbers n springs are too soft for the altezza before yr 2001. after 2001, the suspension is better.
i know this because mine is a 2000 altezza. hence i beli trd sportivo ....but 3k plus lah brand new from winghin kl. :) ouch....
honestly, u might as well get some aftermarket ones like tein...much better handling will be achieved
