Hi there, My corsa b has corsa c sxi wheels 185/55 R15 and i would like to lower it 60mm,

Its allready lowered 40mm on springs and standard shocks, but the rear bottoms out and makes a loud knocking sound with people in the back(but does not scrape),

I am going to buy 60mm lowering springs and lowering shocks off ebay

1. Are jamex any good ?
2. Will any problems occur ?
3 Should the knocking sound go ? (btw my exhaust clears the axle be far)

thanks guys x

you should be fine with lowering your car 60mm on sxi rims without the the arches rubbing, the knocking could be the result of the dampers reaching there limit and bottoming out, so i would say the knockin would go once uprated shocks are put in
