These aftermarket LCA I won't consider using them for a few reasons.
1. The material they used is unkown. Aluminium also got different grade and strength. We don't know if it's aluminium alloy or just aluminium.
2. These LCA not sure have gone through any lab test for breakage and distortion test.
3. Aluminium will crack under stress. My factory machines are using Aluminium bar and overtime I can see fine cracks appearing and becoming longer and longer on area where it is constantly under stress.
I believe those genuine hardrace, skunk2 won't make their LCA like the ones in the picture....it just looks very weak and won't stand much beating on the road and will snap into half.
