Steering rack OEM BMW or ZF

spacers definitely weren’t there. Unbolted rack, bent tabs down, put spacers in, bolted it back up, good to go! Shocker - much smoother ride and quieter engine not that it’s not sitting on the rack/subframe

I run stage 2+ on e40 and daily it. Nobody needs this amount of power for a daily (500hp 3.4s 0-60). Also just hit 100k miles and I drive the hell out of it; just routine maintenance.

nothing has made as significant of a difference as the E46 ZHP rack swap. The biggest night and day difference of any part I've replaced on the whole car.

I went with the E46 ZHP rack (second fastest) as my very first "quality of life" upgrade and it dramatically improved the car.

I have the Z3 rack in my 318is and I like the faster ratio because I drive it through small town Appalachia and these old, small, windy East Coast mountain roads.

I am really happy after installing an E46 'purple tag' steering rack. Absolute go cart :)

zhp rack is my favorite mod, and I have many. Even if you're not tracking, the biggest affects to driving feel are steering and tires. The lock-to-lock is largely irrelevant on public roads but the feel makes a big difference vs the other racks.

I replaced the steering rack on the car because the original rack was leaking. The replacement rack was an OEM from a junkyard. The old rack was a TRW and the new one is a ZF. The steering is heavier overall than with the old rack. My friend says it's definitely harder right than left.

E series steering feel and steering rack put my new 2025 bmws to absolute shame. I can't stand the constant small corrections on the hwy. The steering feels lighter than a cheap Kia. All three 2021 to 2025 feel unstable at speed compared to my E92.

The G30 5 series had broken steering rack... all happened under warranty period too. They got it fixed for free but that's the most problematic new car my parents got.
