Yeah mate if you're heading for drift a set of coilovers with 8kg front, 6kg rear spring rates. Pretty good balance for a daily driver.
Make sure to get a Hicas lock BAR. As some kits only add washers to the hicas mechanism.
If you can handle a bare boot> Strip it bare.. There's a good 20-30 kgs kg's in there.
After the suspension is sorted you should really look at a good mechanical LSD. But if the stocker is in reasonable nick you could probably get away with it for a few months(cause I know stock exhausts suck). If you're really cheap you can get it 'Shimmed up'. But they rarely last more than a year after that.
