The Random E46/ZHP Question Thread

Yeah that's what's going to happen

So let me ask you this cuz I had a theory.

When you brake, the car shifts weight onto the front wheels/suspension. What if the car was rubbing slightly upon the hard braking, would that cause a shutter in the steering wheel. I ask because it looks like the fronts have a very small amount of marks from rubbing about a 1/4" wide path at the top of the sidewall

Not likely, plus you would hear it. My back rubs a bit and every time it makes quite a noise.

I don't think that would cause shuddering. If anything, you'd smell tire pretty badly if it was rubbing that that much. Also, rubbing that bad would have been caught by iND, and I don't think the car would have been drivable.

The rubbing only would happen on the really hard neck jerking deceleration though, stiff suspension normally but under a lot of g force of a hard brake it would bring the front end down so much it might touch a bit. IND wouldn't have looked for that, it was just a visual inspection.

It did smell a touch funny at times but I figured it was just brake smells.

Ugh...

The world may never know

Brakes and tires have different smells. Are you sure it was tires you were smelling and not brakes? I imagine the brakes would definitely be smelly after multiple 150-60 slowdowns.

No idea. Oh well. Guess next time I'll raise up the suspension a touch and see if he same issue returns on track pads.

This isn't exactly a question, but this article leads me to believe there is some nonsense going on.

ARTICLE HERE

This topic has been beaten to death, but I'm having a hard time believing that this dudes car read 228whp on the dyno. Looks like he threw on Style 135's on a regular 330ci too.

I've driven modified ZHP's before (exhaust, shark, short shifter) and they really didn't feel much faster than mine did.

8hp at the peak isn't unusual. What's the issue?
