I have 19" BBS LM's.
I love the wheels. They make a huge difference in appearance, and ride. Obviously the ride is harder on 35 series Pirellis, but the cornering, with a combo of H&R coilovers in second to none. Also, the 19" LM's are actually lighter than the stock 17" polished 5 spokes, which is incredible. I didn't notice a difference/loss in power thru the gears either because of this. On the topic of road damage, I guess it all depends on where you live, and how you drive. I've had my TT in NYC a couple of times, and I just drive careful, and avoid the monster potholes. No complaints so far, besides the attention that my car gets. Alot of times I have people around my car when it's parked, and sometimes I make the alarm go off when I get close, so I don't have to answer silly questions. Anyways, what wheels did you get?
