How to lower the car with standard coil suspension

[RaymondWoo]

Does anyone in Hong Kong know where this can be done? I bought a set of springs from T-Sportline but unfortunately it doesn' t work very well as there is some funny sound from the springs whenever the car goes pass some big bumps on the road...

Did you talk to T-Sportline about the sounds? Maybe wrong installation...
