You guys could also use LA43H instead. These are made of a harder material.

3 of the 4 I broke were the LA43H, I think the harder material is more brittle. the track has changed and I went back to the NOT hard ends, not sure if it is the track or the softer end but so far I have not broken any. fingers crossed.

Thats what i figured but wasnt sure. I will admit it looks like its going to be a good car. I just had the B5 RM and the fit and finish is superb; especially from what AE quality use to be. Needless to say i still sold it and im going to stick with the RB6

I don't know why? I have had a B4.2, C4.2, TLR 22 and this RB6 is hands down the best. Wasn't great when I first got it but after a couple track days this thing is dialed. Shocks are butta, diff is butta. I am setting new personal best each time out. I wouldnt even consider a B5m right now but I guess we will see how they run tomorrow.
