the xb4 is for real.....
ive been racing a cat sx3, and a b44.2, and my track record was 19.00, but last night i raced my xb4 with the same tires and electronics and i turned a 18.6 during the race and my top 5 average laps were 18.7 and i didnt break the harder i pushed the xray the better it stuck....
the xb4 is super nice...
ill tear my diff apart and see if the permatex 2 stopped them from leaking and let you guys know.
has anyone tried any o rings on the shock caps to keep them from leaking and if so which ones fit good.
