The Random E46/ZHP Question Thread

Thanks for clarifying. That would seem very odd (and dangerous).

"ZHP is a garbage option anyway- just some cosmetic upgrades with a different cam and diff to claw back some of the performance lost fitting those hideous and heavy wheels. Any 330 with a 3.46 diff will smoke a ZHP every time. The whole Mafia thing reeks of childish behavior." - an e46fanatic

Just bought two new BMW "hood supports". While I'm sure it's fine not to for these, went OEM.

Some people want to disable it for track use.

Understood but there is a separate way to do that as BP stated.

I actually don't know anyone personally who does that. I wouldn't want to either; the last thing I want is lockup at 100mph!
I found that if you do it right, ABS doesn't intervene, and you can still get the proper threshold braking done.

I don't know about at the track, but at AutoX and hillclimbs I took full advantage of the capabilities of ABS to the point where I counted on it. I'd be interested to hear input on the advantage(s) of disabling it for track use.

My experience with a road car with an ABS switch was my 1990 Audi cq. Big ole switch on the dash that allowed the driver to disable the ABS. Good for deep and loose surface (deep snow and gravel).

For rally use, disabling ABS totally makes sense.

Instead of starting a new thread I figured I'd just ask here; what's the current collective "best battery" for our cars since the Duralast 49-DL is now discontinued? Need to pick up a new battery soon.

Edit: Thoughts on the Duralast H8 vs Bosch 49? Anything comparable to either but a little cheaper?

Hey some people want that. Not me!
