I see two vastly different approaches to solve the same problem

I think I bought and installed that. Hasn’t broken again, but I don’t mash the button either for fear it will break

I should have ordered on the black friday sale... goddammit.

Does ECS offer free shipping? I haven't gotten around to ordering hitch parts yet... Can't get myself to spend the money.

These would make sense for high-beams come to think of it. Now i’m curious.

Fair enough. It also only lasts half as long just FYI.

Report back if it's actually brighter.

Why on earth would you spend 4x as much for a lightbulb when you could get a perfectly fine German bulb from amazon delivered in 2 days?

Weird. Maybe bosch is reneging on quality.

The difference between Bosch and Genuine BMW is the Genuine is a Bosch that’s been kissed by BMW

That video was great.

Is this for the convertible, coupe, or sedan?

Also $110 wtf?! I was expecting like $50

I installed rebuilt injectors from ebay b/c I got a telltale smell of gas (from the o-rings or something inside the cabin).

Now it runs well.

No I understand. I’m not a power junkie, I thought it might be something relatively small and elegant. I’m a BMW OEM junkie. I’m going to keep my ZHP bone stock, and enjoy the “reliability” it...

Good lord, those prices are ridiculous.
$6k for the supercharger. I looked at the Autowerke diff, and I don't like how it mounts at all.
A separate oil pump? Also the intercooler hoses will go...

What's the stock ratio?

I think I need to get a replacement spare tire... is this something discount tire carries?

I didn’t dare fill mine up beyond 20 psi b/c it’s from 2003.

I have something similar, I think it’s my belt tensioner or my AC pump. I’ll have to take a look when I go in to replace my alternator regulator

Very good info. I’ll likely stick with the stock. I’m super hesitant to do any mods, as BMW made their decisions for a reason, and with a supreme obsession to detail. I expect an SC ZHP would...

Does the MFactory remain the same final drive ratio? Does it “feel” the same? Does it introduce noise? Crabbing? Anything like that?

It depends if I can get an M3 LSD for cheap. I’d only want the BMW OEM one, nothing aftermarket.

Recent circumstances have convinced me of the value of an LSD. I’m a little bit hesitant, as my understanding is that an open Diff is nicer than an LSD, as an LSD might cause issues such as crabbing...

Does a Supercharger change the characteristics of the engine (besides power)?

How does an M54 + supercharger compare to an N54?

NO! I’m looking at getting one now; I have to do rear suspension work anyway

Most snow I’ve seen here in 15 years


This car does so unbelievably well in the snow. Not in the sense that it can remove a tree, but in the sense that it’s so controllable, and the traction...

No clue; Definitely not winter tires lol
