Anyone had any experience of the above on any car?

Possibly looking for a new suspension kit later in the year for fast road and light track use. Other contenders are weitec gt coilovers or maybe KW variant 1 (none inox version)

Cheers

But deep down I know this would be more beneficial

Not any personal experience, but I know some people who have used this on FIATs and they heap praise on the B12 kit.
