I usually check my shocks every day before and after running out on track. I usually do 2 or 3 day events normally and I have a leaking shock the first time I took the car out. Sent it back to rush and ordered a front and rear to have as spares. So far I've have 1500 miles on the car and no problems since. I have this hooked up to a nitrogen tank in my trailer. Yes the set up is a bit costly but regular is around 600 bucks. Tank wad 300 and the hose and fill were little over a 100. Well worth the money though
