The Random E46/ZHP Question Thread

<snip> The rail is exactly the same length between the two except the sedan has that extra attachment for the seatbelt.

Recently did a seat swap - installed M3 seats in my sedan and Slater fabricated that seatbelt bracket for me. I am sure he can tell you how to go about it if you need to fabricate one for yourself.

Popular fluid to use is the ATE 200

Try not to use Typ 200 if you don't track your car. From what I understand, it more readily absorbs moisture than your standard fluid. It has a higher tolerance for heat, but that isn't something you'll ever have to worry about on the street.

You mean between sedan and coupe? Yeah you can swap them. It didn't matter when I did it one time. The rail is exactly the same length between the two except the sedan has that extra attachment for the seatbelt.

Thanks guys. Based on that, the seatbelt bracket unfortunately will limit me to sedan rails only, but at least I have the answer I need.

+1. Pentosin. Not familiar with the LV. Not sure of the ZHP requirements on low viscosity. Any related documentations on ABS?

I can't find any right now but I remember reading it somewhere. This is one thread, and far from an official source. Ignore the inter-member arguments: http://www.zhpmafia.com/forums/showt...ke-Fluid-Chart

Honestly I think you would be fine with regular DOT4. I just went with LV.

The seatbelt bracket is a very simple piece of hardware and I am sure you can rig something up using off the shelf stuff from Home Depot or the likes. I will take a picture of it after work and post it here. Actually no, let me go down right now and take a pic...could use a walk given the warm weather outside.

EDIT: Picture of the said bracket

Thanks Anando, but I won't be 'rigging' anything up. I'd rather have a direct swap. It's more headache than I'd like to deal with.

I appreciate the info.

Some people say it may lack anti-corrosion additives but if it is changed frequently it will be fine. But according to ATE and the image below, under normal driving it can last up to 3 years.

ATE SL, Pentosin Super or orginal BMW Fluid is another option as well.

Mike Miller Recommended change interval once a year.

it actually is a very simple solution. i used locking nuts, and thicker steel than the seat sliders are made out of. the factory attachment point on the sedan rails is half the thickness, and riveted on.

are you getting some M3 seats with adjustable bolsters???

if ATE recommends every 3 years for the TYP200 (graph below from vas), then that would tell me it's less hydroscopic that other brake fluids...

personally i use the SL-6.

Per BMW in regards to LV Fluid like the Ate Sl.6

"The Ate SL6 fluid is a low viscosity formula for modern ABS and DSC systems. BMW recommends low viscosity brake fluid for all chassis beginning with the E60 5-series. Low viscosity (LV) is a thinner fluid that works better than a normal fluid in the small channels and passageways in the ABS/DSC pump. Using the heavier fluid will result in a delayed response to ABS and DSC activation and a spongy feel in the brake pedal (only during ABS stops). Ate SL.6 falls just short of DOT5 specs so is classified as a DOT4. It can be mixed with other DOT4 or DOT5.1 fluid. For track use, a heavier high performance brake fluid such as Ate Typ 200 or Motul RBF600 or RBF660 is recommended because of their higher boiling point and because the thicker fluid will thin out at track temps. But for street use we recommend switching back to a LV fluid, especially in colder climates."

No NB, so no.
I need to lower my seat. For some unexplained reason, my NB driver's seat sits way too high, even on its lowest setting, so my head is practically touching the headliner most of the time. With a helmet, I have to tilt my head or tilt the seat back - it's very annoying. I didn't have this problem with my alcantara seats, and the other ZHPs I've sat in didn't have that problem either. My passenger seat is fine - it sits significantly lower than my driver's seat. I figured swapping the rails should fix the problem... I'm hoping.
