Recent Corner Balance on my '89

[dshepp806]

Greetings to all! Great to have such a great NG as this one,....

I've a 1989 S.A. Edition Carrera 911 that has just went in for her service, relating to CB and alignment. I do my best to absorb the CB and alignment threads,..yet I'm not one who's run ANY alignment machines in my life,....SO: I turn this over to my P-Wrench to address.

I've a long standing relation with the shop I deal with,..very P-car aware/knowledgeable guys, who race in GT3 classes,........I do a lot of maintenance on my car but know when to turn it over to Wrenches who do this stuff for a living,....and sometimes my schedule just doesn't permit me to do things I could do,..or would attempt to do.....I rspect these guys for what they do,..and have NO problem with whatever their pricing is (parts or labor) so (within this upcoming thread development , please spare me any comments on pricing of both, as I really could care less,..hell,..I make sure the owner and Mechanic get a case of beer each). Non-issue, with me.

Firstly: the corner balance data I've attached ,..and would welcome commentary from fellow Pelicanites. We'll get to alignment data shortly. I would note that she was loaded with new sneakers before doing anything...dropped my weight in the seat (BTW)

See below,..then render your comments,....of course, all welcomed.

BEST!

Please,....I'm still learning on this stuff,..so allow for the neophytic presentation.

BTW,..forget that noted "49%" line!

Can't be upset with those numbers! For all practical purposes the weights are perfect. Well, the top numbers are. anyway. What are the DW numbers? Driver weight? If that is the case, they have the cross weights set nicely.

For any of the above tables to have any real value as they are being reviewed, A before and after might help. At least to those of us who do not do this on a daily basis.
Since you do not state your weight, do we assume a small or large stature to relate to corner balance weight notations.
Just trying to learn, I am a first time P, owner.

Not so much worries on the previous on this (I wish),..but certainly DID pay attention to the alignment previous(s)......no big need for previous on CB, but would be nice (agreed). However , previous means little here to me,..and am more concerned with the present adjustments,..in this case, I just don't "live in the past"....

DW=driver's weight, for sure> Yes: I provided my driver's weight and this was loaded (and taken into account-obviously),....they certainly followed the procedure correctly as to accomodating the driver's weight for CB.

Just to address "stature",..you'd be looking at a varying) 195 lbs - 200 lbs. as to DW.

Thanks!

I think it to be a great setup, in the end,..but certainly welcome the REAL mechanics who do this day-in,...day-out.

BTW: she's a street car,..she doesn't see the track anymore. i never really did anything special to accomodate the few tracks I've been on,...only out to see what the stock girl will do ON the track..............I spoke with my wrench BEFORE the engagement, and noted that I would prefer an eversoslight lean to peformance, but MAINLY concentrating on NO twitchiness at highway speed (L/R) above 100 MPH and minimizing tire wear over time. Clearly, there's a "balance"....

It was pretty clear the front right needed attention as to alignment,..but this will come later.

BEST!

I would mention that ride height was NOT touched,..and I can provide this spec a bit later.....

For the record, this work session involved turbo tie rod installs/boots (removing the 23 year old stock tie rods and any related hardware)---having to get used to this, BTW,..feels different,..I understand that things will have to "settle-in",..not to mention getting that damned coating off of the new Pole Position tires.........also dropped in front sway bar bushings to rid the 23 year old originals (duh?).....she's feeling really good, mates!

BEST!

Having a little difficulty in following your thread.
How many hours were you charged, and for what services?

[Quicksilver]

I didn't really see you ask a question. Do you have an issue with the corner balance?

The only weight that matters is the weights with the driver in. To see how good of a corner balance you have you want to calculate the front/rear percentages separately and compare them. The fact that the left weighs more can't be changed without moving (or removing) items in the car. In this case the left half of the car is always going to weigh 1647lbs and the right is going to weigh 1522lbs.

The calculation you want for the weight percentage is:
[end weight]/[total weight]=percentage.

For the driver side you have 699/1647=42.44% for the front and 948/1647=57.56% for the rear.
For the passenger you have 628/1522=41.26% for the front and 894/1522=58.74% for the rear.
That works out to a difference of 1.18% from side to side. That is a respectably close match.

Not sure from your post if the alignment was done at the same time. It needs to be because the corner balance will change some as the alignment is changed.

[dshepp806]

You're precisely observant,..as I didn't ask any questions,..other than to get the PP's responses. Hopefully, that clears that up.

I never stated I had an issue with the CB,..I merely posted the dat for responses (seems simple enough?)

In your comments (the final), I agree: I think it a rspectably close match.

I did state in my post that the alignment data would be forthcoming,..miss that?
Clearly, corner balnce is done FIRST (as my P-wrench clearly knows!!!!!!!)

[dshepp806]

@gsxrken

not sure where your difficulties would be?????

I never really dwelled on charges (specifically),..and made the effort to denote that it really is a non-issue with me (reread?)

As to your specific questions (of which I've suggested nothing)....I'll be glad to let you know soon,...however, it's of no significance to me,..and would be considered a waste of time,..but (still) will provide you with my costs. As well,.I'll speak to your specific requests as to "what was done" (the most important question,...($ just don't matter here, for the reasons ALREADY stated)). I'm looking to discuss results,.....that's all....

[dshepp806]

Conditions: a steering rack that provided popping in the steering,...had to change out the 23 year old steering rack (imagine that?). While in there, we installed turbo tie rods/boots. Loaded Fresh Potenzas,..CB'd then 4-wheel aligned....also loaded fresh front sway bar mounts (YAWN)..

Those were the tasks completed (just to get that question answered.

Best!

Doyle

[dshepp806]

See all tomorrow on the alignment results (obviously post CB) tomorrow,.

Thanks for the concise (attentive) constructive responses, thus far.

[gsxrken]

I'm glad you're happy with the work and implicitly trust your mechanic. If you reread my post, I specifically did not ask about cost; rather, I asked what work and how many hours. And the only reason I even asked that is simply that I was just quoted eight hours for a ride height, CB, and alignment, and I have a recent post asking for folks to share their experience in getting the same work done.

I hope I didn't insult you. Like the other poster, I didn't see a question, I didn't see a concern on your part, and I didn't see the hours/services breakdown I (selfishly) am interested in.
Cheers!

[dshepp806]

Understood, gsxrken , as your reminder of your original post content did not mention "costs" (as you noted). In no way was anything taken as an insult.....my apologies, Sir. Was in the middle of a recording session and thought I could multitask everything.....distracted, I'd say. Will fix,....

Again, you're right,..I didn't originally post a "question". It was much moreso a statement,...a "request for observations"....again, my apologies.

I'll get the invoice to gladly extract the things of interest here....and glad to share with a fellow Pelicanite.

Just looking for observations,..that's all. I'll get the stuff (my experience) posted very shortly.

Thanks,

Doyle

[dshepp806]

They installed: new steering rack, turbo tie rod kits, front sway bar bushings, front wheel bearing checks. They never denote the hours, so I have to factor out the hourly rate (which I know) to get the hours charged for this work,....and it seems to come to 5 hours.

As to corner balancing time, he told me that this can vary but expected ~2 hours,..which it was.

As to 4 wheel alignment, the very same above CB comment applies,..again, 2 hours there.

What hourly shop rates are common in your area?

Hope this met the request.

BEST!

Doyle

[dshepp806]

I just realized that I've yet to post my final alignment #'s,..sorry

Here she goes:
