TRW Control arm
snapasaurus
  • Stability:
Rating 5.0

I decided to upgrade to the M3 upper and lower control arms. After many months of research, I went with the TRW M3 control arm upgrade kit. This kit comes with the upper arms, lower arms, headlight leveling sensor, and all the required hardware. The arms also have the upgraded M3 monoball bushings pre installed. With the new M3 control arms I was able to jump from the maxed out -.6 degrees of front camber, all the way to -1.8 degrees. After getting the car dialed in, I took it out for a drive on some windy roads. Every single complaint I have had about the car is now gone. The turn in feels fantastic and far faster than it was before. Less steering effort is needed to place the front wheels exactly where you want them in a corner. Upgrading the control arms on a non-M E9X to the M3 versions is one of the best upgrades you can do for the money.

Pros: fantastic turn-in, faster steering, increased camber, reduced complaints

OEM BMW Brake booster
NBQuade
  • Pedal effort:
Rating 5.0

Surprisingly, I've never had a problems with Ebay used parts. Got an M3 brake booster for $50. BMW wanted $1000 for it so I bought two just in case one was bad. They were both fine.

Pros: both were fine

Zimmermann Brake discs

I went with Zimmerman z-coat rotors and Hawks Performance Ceramic pads when I had my E46. Great stopping power, and low brake dust. The bite was progressive, so it required a little more force on the brake pedal, but it was easy to modulate how much you wanted to brake.

Pros: great stopping power, low brake dust
Cons: progressive bite, more pedal force

OEM BMW Brake pads

  • Braking:
Rating 4.0

Seems like there would be room in the market for a slightly detuned S55 base model without the fancy seats, brakes and wheels for about $5-8k less like the M3/M4: M3/M4 Competition.

Firestone Tires

  • Grip:
  • Ride comfort:
Rating 4.0

I run them on the street in the summer on my 135. Cheap as chips, and they handle pretty well. Want a cheap summer tire that's fairly comfortable and handles well? This is your frickin' huckleberry.

Pros: cheap, handles well

Firestone Tires

I purchased a pair to throw on the rear of my BMW after roasting a set of Pilot Super Sports on the track. For street driving they are 99% of a PSS at 50% of the price. Highly recommended.

Pros: highly recommended, good for street

  • Shudder:
Rating 1.0

Of course, the clutch rivets wore through the flywheel and pressure plate, requiring a new $1800 flywheel.

Cons: flywheel needed replacement
