Barry! Long time no speak! How are you? I hope all is good with the Scooby.
I have the BAT handling kit with my SVT and it really isn't to bad handling the bumps/ruts/holes in NYC streets. There is one killer patch, or was, on 34th, between 10th and 9th which hurt. But, other than that, the suspension isn't so hard that its bone jarring. Coming out of the Lincoln Tunnel, NJ bound, taking that helix close to 70 is fun.

The car is just flat with the kit and well worth the money and compromise.
Edit: I used to work 4p-12a, so I would leave work between 1a-2a and have fun, almost no one else on the roads, so no flaming please! When really loaded, full trunk and and full back seat, I have yet to rub. It lowers the car about 1" - 1.25", so its really not that bad.
