eh nope. I dont think so. Mine seem easy to drive, although my swapped RS is a bit harder to engage smoother, but its a heavier duty clutch than stock.
My STi is doing awesome. Almost 50,000 miles (on a 2005, I know yikes!) it has been launched numerous times, is putting out more power than a stock STi and the clutch still has no signs of any slippage.
WooT!
