BMW parts reviews

Today I will get Pirelli runflat because sounds like it has better thread wear than continental .

It’s Delphi and I bought one recently. Build quality is excellent and it comes with the sock and new hardware.

Get factory msport springs and Bilstein B6s and roll on. The springs will give the car a slightly more aggressive look than base E91 hight while still giving each corner plenty of travel. The B6s will give you a tight, yet smooth ride.

At an absolute minimum, Sachs shocks are worth the money, they're perhaps the one thing that has the biggest impact on ride quality. Being a more complex part than control arms and such, a cheap brand isn't going to have anywhere near the same ride quality.

I use Castrol EDGE 5W-30 LL Fully Synthetic Engine Oil on my B48 pre LCI G21 no issues at all and complies with BMW specifications

Goodyear Ultragrip was good on RWD 535d, tuned

All brake discs are now StopTech Black series one-piece, no detriment to performance vs the ATE stock two-piece, the upside is no going orange on the bells or edges like the stock discs do, pads are still PFC Z-Rated and fluid is ATE Type200, no obvious fade for fast road use.

i recently had to change the windshield of my 2019 G30 id7lite. As OEM wasnt available at the moment an aftermarket windshield made by Saint Gobain was installed. The HUD is slightly distorted to a rhombus shape. Nothing major, still annoying.

I found a warp correction service function in ISTA and was able to get the test picture straight again. After saving and exiting, HUD shows nothing. Reset to factory values got the HUD working again, but, of course, warped. Tried it twice, but no success unfortunately.

I don't trust the BMW oem pumps any farther than you can throw them

I changed the spark plugs on my X5 with Bosch ones. My mechanic showed signs of being upset with me for not bringing the genuine BMW ones... Fast forward to a week ago - the car throws a check engine light and OBD scan shows faulty oxygen sensor heater circuit. My mechanic linked this to the Bosch plugs, suggesting they might not be the correct type. I ended up replacing them with genuine BMW plugs and an O2 sensor, which cleared the codes and improved power. My learning is that Bosch has many SKUs, and it's hard to ensure the exact OE part number, potentially leading to incorrect plug types (e.g., 'double platinum' instead of 'laser iridium') for BMW, costing more in the long run.
