Default Power steering rack leak

Hey everyone, looking for a little advice regarding a leak from the passenger side of my power steering rack. The other day in my garage I noticed some oil on the ground. Jacked up the car and saw a wet spot coming from the front diaper/cover. Removed it and saw that the passenger side boot was torn on the power steering rack and a small leak. Fluid levels were fine in the reservoir.

Is this an indication that my steering rack is in its way out?

I have a competition package model, and noticed that there are two different part numbers for the steering racks. Is that accurate?

Check the high pressure steering line; that is the most common steering fluid leak area in our cars. Its also a good idea to replace that broken boot. Dust and road debris can get into the rack and ruin it.

And yes, the competition package cars have a quicker ratio steering rack compared to the non ZCP M3s.

Thanks. It's not the high pressure line. I confirmed that the leak is coming from the rack itself. Likely a seal going bad?? I'll probably take the boot up so debris doesn't get in the rack piston.

Get the ZHP rack. It has a shorter ratio than ZCP.

My power steering line has had a small leak for over 30k miles. The hose is wet and there are a few drops beneath it. It's not a real concern.

The torn boot should be addressed very soon though.

Do you know the ratio differences between the standard, ZCP and ZHP?
