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?
Anyone installed the Chase Bays E46 M3 reservoir/lines kit? It comes with a restrictor, I think.
Would like to know size or part #.
IIRC, it’s about 1/8” id.
Thanks.
A few folks over in an E46 M3 forum said they'd replaced the OEM high pressure line with an AN line without a restrictor, and were not having any problems. So I'm hoping mine is also fine with no catastrophic events! That damn Chase Bays site has you believe the E46 M3 P/S system kills cats and puppies unless you use their kit.
Good information in this thread on the power steering system. Post #5 shows how to reduce pressure for better steering feel. May also improve longevity of rack seals if you’re worried about it.

That's an awesome thread, thanks!
