opinions please
 

asked about suspension in the technical page but did not get much joy so will try in here

my rear shocks have just gone and was going for a set of KYB AGX's and Eibach pro springs (which i think are close to TIEN-S springs) cost around £720 supplied but new but

how will this setup compare to a set of cusco coilovers, as i have seen cusco up at japperformance parts for £600, but will be second hand

how do these coilovers fair up in real road driving along with other coilovers i have heard they are stiff and bang about a lot etc.

as the cost is nearly the same which would be a better option, buy new or second hand

any opinions welcome i will be using the car for road and trackdays (spare time thing unless i catch the bug)

thanks
