i wouldn't say they're bad exactly, but on a car that i think is otherwise great to drive, this is a real weak point. it does get noticeable at higher speeds. even with a raging 82kw it can get up to some reasonable speeds - it's rated to 185kmh or something like that but even when you're doing 140 it would be nice to have better stoppers. it doesn't owe me anything so i don't mind spending a bit on this improvement.
by the way, nice stable. i like the look of your w123s especially. got something against gasoline?
