Although I'm running RS top mounts I think the Rennline ones are much better. I've had one front bearing fail (knock ,knock) and the dust caps are impossible to remove they cross thread so easily I had same problem as Jackal and you need a specially made nut to use them. Chris Franklin @ CoG had them made specially for me. The dust caps are closed and torqued up to hernia inducing proportions. I sliced the tops off making shock removal much easier like the competition cars. If a bearing fails you can't get a new bearing unlike the Rennline ones. If fitting the Pss10s you will need the Rennline top spring collar for the fronts.
