Hi, I've got Kings all round, lows up front and I think Lows in the back, the back doesn't sick level with the front so I may one day get it compressed a bit.. all up it cost 450 for the springs and a day to fit. It really does firm up the ride quite a lot. Also Ive got the white like 27mm front sway bar which helps a lot keeping things flat though tight turns and most of all helps a hell of a lot with the stock setups tendency to want to keep doing straight through fast turns. I will eventually get around to putting in a rear sway bar one day. If I was to do anything differently again I would go something better up front. with the rear there isn't much choice, the main ones are king and pedders (which suck) the pedders rear spring uses 4 fat leafs, the kings use 6 thinner springs, so they ride wont be as hash on the back Alot of people have super lows in the front which look good but with this cars excessing front overhang and failer to fit length ways into normal length car spots I'm always scraping the front.
