I read a thread of brosters from around a year back, he was saying coilovers arent that brilliant for road use, and so many god damn conflicting views!
I've ordered some silverline x fk's but i'm just wondering if i would be better spending my money on some koni yellows.
I'm just sick of the bangs and clatters of my car, my old XE corsa was the same and this was on koni yellows. I hit a good bump in the road and i just want my car to be silent, or am i going to have to live with it,,,,,
Do i cancel my silverline X's and spend my cash on some koni yellows, with some good springs, but the good springs only lower around 40mm and my car will look pants...

ive had coilovers and bilsteins.
get bilsteins, nothing comes close. ive fitted every possible type of suspension on peoples cars, mainly corsas and other vaux and nothing has impressed me more. trust me, you wont regret it!
coilovers are fine if you want to spend £800+ on a decent set-up such as bilstein, eibach, proshock or leda but most under that are cheaply made mass produced rubbish imo.
I would prefer a top of the range fixed height set-up over a bottom of the range coilover for the same money.

used to have koni yellows myself, and had the same problem, banging and clashing (this is on the softest setting) - now have fk konigsports (still koni shocks) however its 100% better even with the fronts set at the hardest setting, which really doesnt make much sense to me

Banging and crashing indicates suspension bottoming out. Regular banging and crashing would usually mean spings are too short for the dampers (set too low).
When it bottoms out it sits on a bumpstop (usually rubber or polyurethene or the standard ones, which are foam). Bumpstops are designed to soak up the impact shock (like rubber door stoppers on the wall behind doors).
Standard bumpstops are shite, poly are too hard IMO. The secret is to get a good length of bumpstop which will stop the crashing. One good thing about coilovers is that they tend to have a much shorter damper length compaired with regular style so this enables you to run just as low, but fit a decent length bumpstop.
After years of owning a Corsa B and doing a lot with it I found Coilovers are the best setup BUT dont lower them too low. Any more than 50mm seriously reduces road handling. I ran mine 45mm drop front and 60mm spring at rear.
BTW I ran an expensive setup with Harry Hockley GrpA Rally coilover cases with Bilstein 40mm struts up front on a 290lb spring and Spax RSX spring/damper 60mm fixed height at rear.
