I also drive a lowered VW and it constanstantly has alignment issues. The only shops I trust to have an alignment done at are TKX performance in Huntington and Tyrol Sport in Queens. The links are posted. Both shops are great and when my X5 needs an alignment it will go to one of these shops.

TKX: TKX Performance - Long Island's European Specialists, Porsche, BMW, Lamborghini, Ferrari, Mercedes-Benz
