I have Apex on my Turbo'd Bonus, i love them! They are one of the only combinations of springs/shocks that sit the car nice and level instead of arse in the air. The ride is harsh, but i found no where near as bad as previous Spax/Koni set ups. I have the -60mm options which is -40mm on an RS Turbo. You MUST fit adjustable bottom arms though to bring the camber back in line so that it drives nicely and doesnt scrub the insides of the tyres!
