Guys, I've had my S3 for about 2months and had a few drags. Depending on how abusive I am to the clutch, gearbox, diff... Ive had 3 occasions where my launch wasnt the greatest and i've heard a CLUNK in the rear diff. Is this normal? My friends WRX's used to do it when they launched very hard, ie what I did. Drop it around 4500... Just want to know if anyone has heard this? Whats the best way to launch the S3?
