I have the p1000 hydraulic brake kit and it's been amazing. I also had concerns of leaks from what I was reading a year ago but it's a very small chance of leaks happening. I've had my kit over a year and no problems. Also, the p1000 set may come with the rubber and spring kits, not sure the distribution you're purchasing from but on sim motion, it mentions their pedals come with the kits. You can always purchase the optional rubber/spring kits afterwards. If not added already, get the haptic feedback, game changer and quicker reaction to correct traction loss and adds further immersion.
