BMW 330 ZHP alignment and data + Pics
-
I thought the ZHP came with more negative camber?

Me too

-.5 degrees of camber (for a total of -1.1 degrees) according to this.
-
I initially thought they were different......but the hunter road force machine...said what it said.

Post #5 solidified for me. I really was only concerned with the toe...as I was chewing through my new tires at an alarming rate....
-
Sounds good to me :)
The guys down here at Autobahn South build race cars and specialize in suspension so I will just hand them the keys and let them work their magic anyway when the time comes. They have earned my trust without question.
-
Please ask them what they use as specs so we can further complete the research...
-
-
-
So the roadforce machine told them what the specs were for the car? Is it possible that the machine incorrectly grouped them together? I could swear my car has negative camber... (has only ever been aligned by BMW).
-
Well....the roadforce machine did not pull up seperate specs for the zhp. It pulled up 2004 330i sport..
Thats when I brought it up and quickly did some research online. I doubt the specs would be all that different...but the specs shown are for previously discussed 330i. IDK to be honest with you....
Again...I was also a little surprised they didn't ballast the car....
-
Damn that car is sexy as hell. Anyway to PS out the fat a$$.

Thats what 4 days over Thanksgiving and a porter cable will do. Gotta have mazerna polish, Wolfgang sealant, and dodo juiice hard candy wax. Process is not for the faint of heart...but I prolly saved myself 500 bux, and I can do it whenevr I want to now...for free.
EDIT: Oh yeah...it rained that morning (5:00 AM) as I drove 60 miles into work. That pic was taken about 6:00 PM....
Pure nastiness.
-
Gonna have to do that, after I get my front bumper sprayed.
-
Imlearned how to do it.....in about...well...instantly...hehe. Had a lil guidance from a buddy o mine though.

Looks incredible.

I wish I was that industrious... :P

If I lived in dane's neck of the woods, I'd be paying him to detail my car.

Just because the Hunter said it's the same as a regular 330 that doesn't mean it's correct - it was programmed by a human after all.
if/when I get an alignment, i am gonna verify with a dealer and/or specialized indie shop that the ZHP does have more (-) camber or not.
So what was the reason to get an alignment?
regular maintenance or was it having some symptom/problem?
If it did, what was the problem?
did the alignment solve it?
Thanks.
-
I got the alignment because tire wear dictated it.
The dealer concurred with the zhp spec, as well as the link (post 5), who also verified with the dealer.
It wasn't only because the computer said so....did you read the above?
-
Hmmm, Interesting, the ZHP requires toe out instead of toe in as in the ZCP 330.
I'll be zeroing mine out once I lower and change control arms.
Positive toe would make the car very twitchy to steering input at highway speeds.
-
worth noting?
I too need an alignment -- you guys will love the reason why: noticed the lock nuts on both tie rod ends were totally loose. Which was neat. Anyhow, didn't lose a wheel but the front tires were wearing quickly & unevenly (big shocker).
Anyhow, sold the tires & wheels in question but now that I have the 135's back on the car (with nice bald Michelin PS1's), I'm thinking about new tires. I've got a new set sitting in my TireRack.com wish list but before I pull that trigger, it's alignment time.
After reading this thread and the e46fan thread linked in post #5, it seems all we need to do is make sure the tech doing the work chooses coupe vs sedan and uses the Sport specs for 18" wheels (the std ZSP wheel being 17"). See first image below.
Easy enough but here's the curve ball. Looking at the add'l images below, lifted from another alignment thread here on this site, it seems the setting might change if you are running the OE BMW shock tower reinforcement plates (BMW p/n 51717036781).
Or is it that you simply realign to ZSP 18" specs after installing the plates? Discuss...
Note: the data below is all related to coupes.

When I had my alignment done, I asked the guy to align according to lowered sport suspension but he told me that it doesn't matter because the machine is set up based on VIN#. I don't know how well it gets aligned, but I guess I'll find out soon enough. Either way, it was the only shop that would touch my car because most shops won't touch a lowered car. :(

Update: according to Turner Motorsport, a big proponent of the above-quoted reinforcement plates, alignment specs do not change with the plates installed.

I wonder if just a bit of extra camber in my rear would help with the deep dip rubbing of my tires. Since I only rub on deep dips, would the extra camber wear the tire far more than the occasional rub? I'll probably rub at least once every time I go out if I'm not watching certain dips.
-
-
But would extra negative camber be worse or better for tire wear if I only rub lightly once and a while?

Worse. It will have its cost. Additionally, a rough thumbrule you can use is.... for every inch you lower your car, you will produce about 1* of negative camber.

OK....so what I'll do today is have them maintain the camber I'm at now....since I only get occasional rub and my next tires will be 255 instead of 265. But align everything else to spec. Does that sound logical?
-
Yes.....but...
Be advsed, that with your setup, you'll never see the BMW spec's.
-
ok gotcha...i'll report the numbers if anyone know how to read them to see if they did a good job.. :S I'm newb with alignment.

Then he drove it and fine tuned it from experience in feeling it!

Are those the final readings? Why would he leave toe like that on the right front?

This was the print out after. He was saying how the car is lowered the camber will be more than normal which you said already. After that print out he test drove and put it back on the ramp for another minor adjustment using just his senses.

Putting mine with your's as a comparison.
Wow.....he didn't have to do a whole lot. Didn't do anything to camber or caster and changed toe like 1/8"

I would love to know where the specs come from....as ours are different.
