I have a 1.6 CL and I have Mk2 Golf coilovers on my car.. so maybe check out Mk2 springs aswell

It says those springs are for a GTI/VR6 so they will fit your car but might be a bit stronger because the VR6 engine is a lot heavier than a 1.6 lol
I'd also suggest buying a shock & spring kit because if you put lowering springs on your standard shocks, the ride will be terrible and the shocks will end up fooked
