as for quattro: i first did the clear bumper lights too but switched to all amber, i think it looks cleaner. im not sure on the gauges though. they should just slip over like the previous people said. and i test drove a blue 01 a4 quattro 5 speed on friday. that car is amazing and handles great. pm me with some pictures please. good luck with your integra
