if you lower a car more than say 40mm on just springs you run the risk that it will bottom out the struts and will damage them.. so best getting a full kit.. pick them up prity cheep up off the bay

I've had 60mm Jamex springs on standard shocks for about 3 months now and had no problems but you should really go for uprated shocks too if you want your car to handle alot better than standard.
Also, on just springs, the front will only go down to 50mm max, not 60mm.

hello
im thinking of buying a pair of front jamex springs for my corsa b -60mm
but i'll use them on my standard shocks. is that a good idea?
apart from the shocs could it damage anything else?
