Alloys are one of those things that you can get so wrong on a car, especially on a car like a Golf, but you have picked a set of blinders.... I really like them
As for coilovers, hmm, very VERY hard... but it really depends what you want... I have had my experience of super hard shocks, and I hate them in an every day car... my golf doesn't even have coilovers and yet it shatters my teeth and it pisses me off
if it's just a fun car, then go for coilovers, however if it's a daily runabout, I would just get some lowered springs and some good quality standard shocks... but then again, I am from Norfolk
