They are great, I always use them. Had the same on my BMW E60, Silvia, E92 etc etc
I do however need to buy RCA spacers for the front as there is awful knocking and banging currently from running low.
I all so may have to shorten the upright on the front suspension wishbones as im pretty sure its nearly bashed the whole way through the inner wheel well on both front sides.
The RCA spacers will correct the camber however which i am in need of to make the wheels fit without flaring the arches a bit so im not sure what my best option is currently.
Does anyone on here run super low?
