Hey Guys, thought this might be of interest, just rang Heasmans in Sydney about some bilsteins for the Stagea, told them it was a 98 S2, he didn't even question the car model, put me on hold for 30sec. came back and gave me a price of $285 each for the front $235 for the rear, no mention of GTR, GTS-T. Said he had them in stock.
Going down tomorrow to check it out
