Yesterday while I was racing the Ford, I went over a small obstacle and suddenly the Ford drove very strange. I inspected it and found that the H-bar was broken. Luckily I had a set of extra PN-Racing H-bars lying around, that I hadn't tried out yet.
So I selected the softest one and put that in place of the broken one. I think the Ford got even better grip with the rear tires with this H-bar so I would call this an improvement. The reason why I selected the soft one was exactly to get better grip on the rear tires.
This was the first vital part to break on my Mini-Z. It has taken some abuse by now so I think this is OK. I didn't expect this to break though. Hopefully the new one will last longer. At least it is made of Carbon Fiber. The first CF part on my Mini-Z
