Suspension Advice

[jonnyfox]

On my S2 I tracked and used for road Bilsteins, 36mm and 46mm suspension (Ohlins in my case but the brand is not the point). An S2 Bilstein damper is what it is, soft and not particularly exciting. 36mm dampers (Ohlins) required more set up here and there but worked really well with an adjustable ARB set to full hard (350/425). 46mm dampers (425/550 Ohlins) were as Alan says different (so was the 36mm for that matter) BUT it was night and day better than both, with an adjustable ARB set to full hard. Pointy and pliant with almost no need once properly set up to change be it road, track, wet or dry. If you are looking for the lesser hassle OE option but way way better, it's 46mm without doubt.
