I can’t comment on the fitment bc I have the shims Volke was selling, so buy at your own risk.
Edit: Actually…they do have 0.5mm thick shims. If you search “shim 10mm 13mm” on their website, you’ll find other thicknesses too.
Edit 2: Looks like they’re charging $30 for shipping regardless of the quantity. I was gonna buy a pack to compare them to Volke’s, but that’s not happening now lol.Last edited by SQ13; 06-15-2024, 11:11 PM.

Hi all,
I've also bought and installed the black tag rack from LPSR in Australia. Its worth it. One of the best mods I've done. My M3 is a 2001 and MK20 DSC. I have read this whole thread and am happy to just drive with the DSC off.
I do however have 1 issue since installing the new rack. The steering is pulsing when turning from left to right when the car is stopped and engine is idling @800rpm, parking maneuvers basically. The steering wheel judders. It seems the pump pressure can't keep up with the rack.
This only started when the new rack was installed. So first thing we did was replace the pump with a brand new Bosch pump. Nil fix.
The pressure hose was replaced during rack install.
The ps fluid reseviour was also replaced.
New Redline D4 ATF fluid.
We have bled the system countless times.
We also reinstalled thw old pressure hose because there is a restrictor built into it and we wanted to eliminate a problem with the new hose. Nil fix.
I've been in contact with Lucas in Australia and he is being very helpful to try to solve this issue.
So from reading this thread I am starting to think about pumping issues.
Can anyone shed any light on it?
BBRTuning, Did you have any issues with your system after installing the black label rack?

However, with this LPSR rack, now in both my M3 and my ZHP, I occasionally get a sudden very brief dropout/pulsation in the assist when the front is heavily loaded in a corner and hitting a bump, especially when driving hard for a while (hot PS fluid?). On the ZHP I have an upgraded cooler too. Both cars have tons of tire, so lots of load on the PS system, but this didn't happen with the stock or Z3 racks. It's a bit unnerving and feels like extreme bump steer although I do generally know when to expect it. I do have a bunch of the Volke shims in my M3 pump, although interestingly I never really found those had much effect.
I also found the steering effort to still be too light for my liking with the LPSR black, and it the steering weight doesn't really build up as you turn in. I'm going to remove all the shims out of the pump and start over, as a test. I wonder if I've put too many in at this point or something.
