handling is great on nice roads, but you'll think twice when your on crappy roads.
The trade off is worth it compared to the stock shocks but if i had the choice again i would have either gotten new ones with EDFC, or the hks ones with lower spring rates, or the sydney kids bilstein group buy which are correctly set for aussie roads. used jap coilovers are hit and miss so make sure you get them tested.
Like i said you do get used to the stiffness, just depends on your comfort threshold and how you like to drive. It doesnt bother me anymore and you just adapt your driving to suit like knowing which lanes to drive in and avoiding bumps and holes.
Dont forget swaybars...they make a world of difference.
