Suspension

[lawser]

I couldn't comment on FK other than they are the cheaper option for coilovers v's KW.
I think you won't go far wrong sticking with Boge Shock absorbers (OE supplier) The turbogas range may be an upgrade on what's in there now? Said to be not as harsh a ride as some brands eg koni/bilstein etc.
Springs only really need changing if broken or you want it lower/firmer ride. I would give it some thought as to how you want the car to drive, roller skate handling is not usually very comfortable and speed bumps become a nightmare.
Cars with the Sports suspension option (code for this is 1BE on the vehicle data sticker) are usually 20mm lower, this spec may be as much as you would want to go.
Other than that I would also consider using S2 front stuts which I think are an additional 20mm lower but also use a larger diameter shock absorber, so something of an upgrade but would not be bone jarring - rears being quattro not compatible unfortunately...

Can anyone point me in the right direction regarding the Boge shocks.....Are they the same as Sachs shocks ?

cheers,
