On my past jumper I ran the stock black springs with the LCG fuel tubing shock mod and an extra 1/4" tubing on the lower shaft w/40wt oil. I also used the Vantage racing HX-3 wheel and tires. I never had any problem with it rolling over. In fact after I did this it would actually kick the rearend around in a full skid. I was totally pleased with this setup, never blew out a shock nor did they leak, this is after many 15ft+ drops from jumping at the local BMX track in Louisville and the local skate park here. It went through hella punishment and never gave up and since then others with Savages around me have done the same with the same results. Good luck and let us know what you do and how it turns out.
