very promising thus far, but i also had Apex lowering springs (by 15mm) also, so haven't really had a chance as such to thoroughly test car! However, the car does feel a lot stiffer, that's for sure! When i go over Sheffield's SH*T rods, my undercarriage doesn't sound and feel like it's going to drop off now!!
So yes, i believe this has been a worthwhile mod, and at a very competitive price no doubt!!
