OEM BMW Hood struts
kiznarsh
  • Ease of lifting:
  • Holds up securely:
  • Smooth motion:
Rating 4.5

After Christmas I addressed the pulleys and tensioners after closer inspection. The idler pulley was OK-ish but at this point...yeah. I accidentally bought an extra pulley...Removing & replacing the rest was pretty easy...The belts are in great shape so I'm not replacing those (I know, shocking). And of course it wouldn't be a kiznarsh project without replacing hood struts. So much better now you guys.

Pros: easy replacement, better now
Cons: chassis brace annoying

Goodyear Tires

I’m a big fan of Goodyear Eagle F1 asymmetrics. They strike a nice balance of sporty with reasonable wear and good rain grip. They have a decent rim protector

Pros: sporty, reasonable wear, good rain grip, rim protector

EBC Brake pads
Rsipad
  • Braking:
  • Dust:
Rating 2.5

The initial bite is really, really good on the street, and the pads feel very good. I never had issues with overheating.

The life of the front pads, however, wasn't very impressive to me. I got about 8 months of daily driving (75% highway miles), 20-30 canyon runs (roughly 35 minutes each) + 2 trackdays (my 2nd and 3rd ever) out of them. I had to cut my 3rd trackday short because the wear sensor came on, and then within 10 minutes, the front pads were metal-metal with the rotor, and I went off into the dirt.

Pros: good bite, good feel
Cons: short life, metal-metal

OEM BMW Brake discs
gdl_E46
  • Braking:
Rating 2.0

If that's a factory BMW floating rotor keep a very close eye on that. Have seen more than one of those come apart (crack gets to edge, ring breaks away from hat), locks a wheel and full sends you in that direction towards the barriers.... Good buddy totaled his z4m and did like 6-7k of armco damage when that happened

Pros: close eye on factory rotors
Cons: rotors can break apart

OEM BMW Water pump

The water pump had a micro leak that would spray coolant on the air box. Never enough to make me want to go through the trouble of replacing it.

Cons: micro leak, coolant top-up
