Just purchased my second 4200 a 2002 manual with skyhook. I am looking to sharpen the handle and reduce the role, dive and wallow. I had my last CC lowered and geo'd to GS spec by Matthew at Giallo which made quick a big difference to the car. This time I am considering doing the same but just want to get some members take on whether to go down the ARB and or lowering spring upgrade route instead and which gives the best results. Would upgrading the ARB's and lowering the standard springs yield good results? I know several members recommend the FD stuff but has anyone much experience with H&R springs?
