I have these from Bimmerworld, with NT-05 mounted. I like them, they feel very light - you notice when you take the OEMs off!.
So far, 4 track days, no sign of problems with bending and I managed to knock the alignment out on my M3 by hitting a kerb without bending a rim.
The best advert I have seen that made me feel better was that a team running in a SCCA Pro IT race was using D-Force LTW-5 rims. I think Turner sells them which somehow gives me confidence in their quality. I was looking for a picture. I also figure a bent rim is cheap to replace!
