Anyone in the I-Club from Westchester County NY who knows of a decent shop to buy and have installed suspension components?

Half the shops will kill($) you if you show up with your own parts. Others are not familiar with performance parts, and can figure out what the right parts are needed to install say suspensions for the WRX wagon (such as do you or don't you need a pillow ball mount or camber plate for the rear with a particular set up).

Has anyone had work done in Westchester?

Thanks
