Apparently, there's much needed restriction in the E46 M3 power steering high pressure line (pump to steering rack).
Anyone know what size this restriction is?
Or, if anyone has installed the Chase Bays E46 M3 power steering reservoir/lines kit, it comes with a restrictor (I think). Would like to know size or part #.

(Posted this in the track forum, then realized this is probably a better place, sorry for double.)
