Koni set up is better for a road car unless you spend a ot of dosh on decent coilovers as above you are looking at 1000's

No the koni front shocks do not have top dust caps over the adjustment knob.

Rears are adjustable in 3 positions by pulling the plastic sleeve done and pressing a button in the top of shock body and twisting.

I have had Gaz coilovers on mine and it was the worst money I ever spent.
I refitted my Konis and always used std springs.
