i just installed my BC BR coils last week and they are quite good.. . As I use my celi as my daily ride. BTW mine are on stock 16's atm... still waiting on my rims. And that being said i might stiffer springs to go lower... atm im running 5kg at the front and 6kg in the rear.Go with BC. I have them and they are great. Only thing I regret is not getting stiffer springs but that is what Swift springs are for.
