I started off with H&r springs and was very happy with them, but have since changed a few times to try out different coilovers.
Had Bilstein B16's which were great, but did not go low enough, then have gone for some FKs (which don't have the dampening settings, and as such bounce all over the place,shockingly poor ride IMO) Getting some AP coilovers fitted the end of the week, which have the dampening adjusting, and can change the ride height quite easily.
