Ahhh if you're using Factory Rubber Top mounts then you're fine... Some people forget or don't know about the coilovers they put in have solid upper mounts so basically instead of rubber on metal, its metal on metal giving you the clunking sounds at times.

Depending where you're located... PM Senna on here or contact Heasman, Road and Race, Spinning Wheel Tyres, East Coast Suspension =)
