Hi guys Appreciate this has been done before BUT can I get a confirmation that the following work I'm about to get done on my C63 wagon is:- 1)Worthwhile 2)Not going to lose OEM drivability 3)Correct products I've ordered the HR lowering springs which I believe is 20mm all round drop. HR spacers 10mm all round with longer bolts (obviously). Also having a Milltek secondary cat bypass done, not touching the primary or the resonators. I don't want a 'slammed' look, just slightly lower, slightly better stance from rear/aggressive and increased devils fart noise but I do NOT want a car that sounds like a boy racer who has a hole in the exhaust if his 40 yr old Clio. Please advise if that is the correct products and method. It's being done locally by a tuning garage for around £1100. Thanks!!!
