OK - I've just fitted sportlines to my 172 cup and I'm not blown away but I'm pretty impressed - they don't seem any stiffer but give a better quality ride than the standard springs - maybe it's because they weigh a ton! They have yet to settle and I haven't taken it on track with the new springs, but I'm pretty hopeful.
How much are my old cup springs worth on ebay btw? they're in good nick.
Cheers
Tom.
