Torsion bar Indexing

[mweeks]

When I bought my car it had been lowered already. It has the stock 23.5mm bars currently. I know there is an excel program available to calc some setting, but that looks like it assumes a stock initial setup.

 

I am installing 30mm hollow bars, is there a preferred height measurement from the BANANA BAR TO THE HUB that I could use as an indicator AFTER the 30mm bars are installed that is ideal?

 

Thanks for any help.

I have proceedure to index listed on the 944-spec website under 944-spec tech.

Here is a direct link to the proceedure. I developed so contact me with specific questions.

There is not prefered measurement. Ride height should be level measured at the rocker for the entire car. A little up or down in the rear will impact balance. There is no "perfect measurement" as it depends on how low you can or want ot run the car. I will tell you that you do need to watch suspension bottoming as that will limit how low you can ultimatly run.

Ok,

 

Then here's another question.

 

What is your measurement from the top of the fender well to the ground?

I have no clue?

 

I have some measurements some where, but I think to the rocker the car is like 4", but I could be off by as much a 1".

 

I run mine about as low as I want to go based on remaining suspension travel.

 

Here is a side picture.

Knowing the tire diamter is 23.86" I'd guess that the rear top fender wll to the ground is 24" or so

I just had the 30mm put in and my indexing was way off per the alignment shop. I have really no clue how to do it, but my alignment guy said the factory allows for 10 degrees of adjustment once the spindles are set.

 

I had a 4x4 set up all last year and can't wait to see and especially feel the difference. He also said my front end was way out of whack.

 

I need to get new bushings for the front sway bars....is this an easy "do-it-yourself?"

Yep. It's easy, but you're still gonna get yer ass handed to ya, Jason!

changing the bushings OR racing?
