Cheers AWBimmer I will keep on researching BC and talk to those guys you mentioned. I'm glad your enjoying your car, after all that's why we own them.
regarding "cheap" our cars always cost more to mod than say a honda or scooby. for example a scoopy intercooler would cost a couple of hundred quid where as ours are over six hundred, so in terms of coilovers when you look through the catalogues other cars will cost less for the springs and an e92 the price just jumps. That sort of pisses me off a bit.
So I think £700 for an e92 is on the Cheap side and I'm not complaining if they are that good then finally a company who isn't ripping us E9x owner off
