Mine are only a month old now so no suprise really they are still ok..
Yes, there will always be exceptions and yes you only get what you pay for. I came very close to choosing the buddyclub N+ set...800quid is a fantastic price for what you get with that kit.
I was pretty intrigued by the BC Racing coilies, and after lots of research on the net I found ALOT of positive reviews. I barely found any problem stories...of course time will tell. But the banker for me was the availability of parts, they are completely serviceable and all parts are in stock in the UK..next day delivery. I am of the mind that making any car lower and stiffer and you will experience problems, I could spend alot of cash on the best coilovers avilable and spend a few months driving round worcestershires b-roads and they, or something else on the car, will be ronnied. Solid top mounts and lowering/camber etc is not ideal for our roads.
I'm hopeful they will be fine for me, they certainly perform well..and they look well made to me also. The spec is good, the price is good...was worth a shot imo.
If you have any doubts stump up the extra 200 and get the buddyclubs, but so far I am happy with the BCR's.
