Kyle mentioned Sarah's book talking about the roll center. Google Preview, if you don't have this book go to Amazon and get it now for under $10 shipped!

The main thing that caught my eye.

I have been going about this wrong all along, for two reasons, or rather two mindsets. For one is I'm turbo, stiffer front suspension helps reduce wheel hop. Second I always figured the car is going to lean forward and to a side anyway, thus might as well put stiffer springs up front so that that limits how much the front body rolls. What I'm going to try to do is put the Eibach springs in the back, they are much stiffer then Teins and B&G's, they also lower the rear 1.2", so it shouldn't look like the car is dragging it's butt.

2J Racing, just north of Atlanta, has all the "fixes" for our beams. They hot bend the beam on an alignment rack and can set camber as well as toe in the rear (for less than $100.) They also do this:

I wish someone out in SoCal or at least in california/arizona/nevada can do this. I really like the results I am seeing due to the panhard bar conversion. But worst case scenario, I might end up driving out there just to get the job done in the future. The things we do for the performance of a little sentra...

I was thinking if the convention is in GA next year (still up in the air) that I would combine that trip with a visit to 2J.

I keep thinking that bending the beam can't be as difficult as everyone makes it sound.It's a pretty straightforward idea,as long as the prep work is done right.I'm going to try it sometime this winter,as I have use of an alignment rack and all the necessary bits.Since I have a lot of experience bending stuff that wasn't meant to be bent,I feel I'm halfway there.

They will bend the beam without panhard conversion? It sounded like they wouldn't do one without the other!

I am pretty certain that they will do the bending without the Panhard bar. They do the bending on an alignment rack and the bar conversion on a lift. Check out their website 2jracing.com.

Sorry, that is the wrong address. It is actually 2j-racing.com. However, when I tried that link, I got an error message today. They are also on Facebook.

I didn't see it as an individual item on their site, http://www.2j-racing.com (down atm), but saw beam bending as an option for panhard. Might be worthwhile for me to just drive down then instead of doing it myself.
