B8s are massively uprated over stock sport shocks, yes they're better if you're on flat windy roads etc but all round a bad idea in the UK on what is already a very stiff car if your driving route has any poor condition surfaces. Spoke to Bilsteins tech department before ordering myself and they said their B4 shocks are equivalent to the sport damper specs, but with a longer piston that also allows them to be used with non-sport springs. The B8s are uprated shocks designed for aftermarket lowering springs i.e. Eibachs (although theres plenty running them with B4s with no issues)

Just found out i have the M Sport suspension,but will be taking your advise with the B4's and non sport springs

Eibach springs, im going for the non sport springs, do you by chance know the correct Eibach OEM part number as I want to stay with the same height as factory, not into lowering the car

Also want to replace the rubber shim pads upper and lower all round if you could assist with the correct ones also please

Cheers

Not aware of Eibach making any springs that aren't lower than stock, most people on here use Suplex for OEM-style replacements. Ironically, the Eibach springs are actually considered a more compliant ride than stock as they're progressive springs, so more flex initially than stock but stiffer if you really throw the car about. Something to consider anyway.

Reagrds the shim pads, check the following links:
