Both My sons car and mine run stock arms. We've found even with stock bushings and bind the front end still rises to quick. Front rebound needs to be tight to slow it down. Both leave quick enough to go red on a .500 Pro-tree. I foot brake mine. This year 13 outings. 1 5 rd, 2 semi, 4 win. R/T ave for the year .029, 4 R/T above .050 all year. I'd say the stock stuff works pretty decent.
