I'm using Dali racing bars with momo rookie seat. They are pretty easy to install and are very good quality. As with RM, I saw it in somebody elses. If you're tall, u might want to opt for RM's. Cause they do not limit the movement of the seat. I'm 5'9". That's why I choose DAli racing's. Cause they look more rigid and strong. Don't forget to get the SCCA bars if u opt to get the Dali Racing's.
I uses Dali racing harness bars and very satisfied with it. It is very good quality and easy to install. If you're tall however, u might want to choose RM's. Cause the Dali limit your seat movements. I'm 5'9" and have no problem with Dali's.
