Hey JP,

Here is a link to a PP thread about corner balancing utilizing bathroom scales:

Scales

[Brad Roberts]

Those are the ones I have used in the past.

I have a Scale/Lever system that uses bathroom scales (had to start somewhere) Its a complete kit (minus cheapy home scales) I think I paid 200$ for it. Works well. Semi dificult to setup, but works.

If it involves smoke, mirrors, wires, levers and duct tape, it's right up my alley. (IMG:style_emoticons/default/rolleyes.gif)

Gotta drag out my Harbor Freight cataloge and see whut the Chinese do.

Those are the ones I have used in the past.

Ah.....what's the conversion factor? Looks like 3-4 to 1.
Are there 2 of these rigs or 4?

[J P Stein]

Ah....looked at the thread. I can make some of them
outta wood....use a 2:1 ratio....in keeping with my CSOB philosophy....then convert them to firewood.
I detect the formulation of a plan here. (IMG:style_emoticons/default/clap56.gif)

I seem to remember a picture of some kind of lever looking hand jack that has a gauge on it, it's made just fer corner balancing. It has a lip that hooks onto the lip of the wheel and you pick it up just far enough to move a piece of paper from under the wheel. Anybody used one of those?

[Dave_Darling]

Nope, but I've seen some used at the track. They're considered "old school" now. They're not tremendously accurate--the measurements don't repeat that closely. But they are a damn sight better than nothing at all...

I guess some of us are "lucky" to live in big cities where we can drive to a dozen different shops within a half hour radius that have some of these spendy tools available.

There's gotta be some kind of industrial/freight scale that has a higher capacity and is decently accurate without costing a fortune?

[J P Stein]

I guess I really need to get a good book on suspension tuning.....any suggestions?

I was doing some day dreaming at wurk and got to wondering about weight jacking with the anti roll bar....or just adding/deleting roll stiffness to one side (IMG:style_emoticons/default/confused24.gif)
This new Tarett bar *seems* to make it easy. Some scales would prove/disprove this WAG.

Our AX venue most often includes a double loop around 2 180 deg sweepers or a sweeper at one end and a hairpin at the other.....kind of a mini oval
with joggles in the straights. I *think* a guy could make up some time there if the car was set up to handle those sweepers better. ...or maybe I should day dream bout other stuff. (IMG:style_emoticons/default/blink.gif)

So may adjustments, so little knowlegde.....I kin turn this thing into an evil handling pig.

[J P Stein]

Someone (Don?)asked me to post the camber settings after I was *done*.

Right on -2 deg. There is nuthin' more to be had. This is with the ride height dropped .75 in. The A arms are just below(ball joint is lower) level. I get more neg camber thru the whole range of suspension compression...go figure

There is no binding anywhere in the suspension travel range/full stiff/soft settings on the Tarett bar.
I furgot to take a pic....trust me (IMG:style_emoticons/default/biggrin.gif)

The rack spacers are in....thanx, Chris....Tie rods run uphill (higher at the steering knuckle) just a bit.

[Jeroen]

Hey JP,

So, when can we expect the first running report?

cheers,

Jeroen

[J P Stein]

With luck, next weekend. It's still gotta go to the alignment chop.....he can be a stinker to get into.

There's a SCCA "test" AX next Sunday....A DE at PIR the following Friday. I hope to make one or both of them.

[Dave_Darling]

As for books, there are a few oldies... One of 'em is almost as old as you, JP!!

"How to Make Your Car Handle", by Fred Puhn. Old, but still fairly relevant.
"XXX to Win" (Prepare to Win, Engineer to Win, etc.) by Carroll Smith. More oriented to all-out race cars than street cars that see the track, but a lot of good info.
...Rats, there are others I know but I can't remember the titles offhand. I think one was "Race Car Engineering and Design" by Paul Frere?

Anyway, there are lots of good books on the subject. I have found that relatively few of them deal with our particular form of madness--they either talk about scratch-built race cars, or Stock Cars (NASCRAP stuff), or other such-like, but most don't deal with street cars.

what benefit does the aftermarket strutholder do/ have? is it like the cambermeister / elephant racing monoball camber keeper thingy's ? nice setup..looks great on your car! .....i like the clean look of everything without the cool air bok / fan and all the ducting....looks great!
(new to the whole aftermarket thing (IMG:style_emoticons/default/cool.gif) )

[J P Stein]

The Tarett mount is offest. It gives more negative camber....also has a monoball in there.

Hey, Jeroen.........

OTG, just add gas & oil and it'll be ready to Rock &.....ah.... head for the alignment chop....then Roll.

Speakin' of rocks, that's what if feels like when I plop
my skinny ass down on a fender....no move.

[J P Stein]

Thursday morning we go to the alignment shop.
That means that tomorrow I get to wake ulf from its "long winters nap".....that's always fun, particularly when I have to do it by my self. I disturbed many things that were nicely sealed up.
Maybe I can call on one of my retired buddys for moral support....I'd supply ear plugs and a gas mask.

I would like to take this opportunity to bitch about
the price of Mobli 1......64 bucks a case.....auugh.

Anyhew, if it don't rain on Sunday and all goes well,
I get to go AX and see what it feels like.

Schedule, Jeroen, schedule. (IMG:style_emoticons/default/biggrin.gif)

[Dave_Darling]

JP, give a look into Delvac oil. Comes in 4-qt bottles, and is supposed to be a very good synthetic oil. Intended for diesels, but also rated for spark engines. I believe that it can be bought for less than M-1 pretty easily.

It's even made by Mobil, if that's important to ya.
