I get it; you set the pinion angle so that under load at launch it is straight.
What about the chassis mounting location of the upper links? Varying the upper rod length will adjust pinion angle but you could vary the anti-squat of the suspension by moving the chassis pick up point up and down as well. Seems that would be very handy to tuning how much weight transfer the car gets coming off the line. Or did someone already figure this out for an FD? Seems tire size may dictate different optimal upper link angles (more or less anti-squat).

Wow Eric I've always admired your car ever since I seen it afew years ago.
Its coming along real nice. I remember you used to have a T88 right? Still have the T51R?
Also what kind of power will you be making?, it seems like your getting really serious and making a all out drag car
Anyways, good luck with your car. I can't wait to see it perform

I had the apex turbo a long time ago then swithed to the greddy T88 two years ago and now I've got my HKS T51R KAI

I forgot, we also had to build a new transmision mount because we aren't using the stock power plant frame anymore. We also had to make a new drive shaft in house. I'll get better pictures of the final project today.

I took it out for a drive last night and everything seemed fine. It was just down the road to grab a cold one so I didn't get to get silly in it yet.

If the panhard is not nearly parallel with the axle housing you also get lots of jacking and binding whenever the car is cornering. Drag cars only go straight, but at launch when the car squats the axle is going to move sideways under the car and make the car wish to crab off the line since the drive is effectively no longer centered under the car.
I can't see the tab where the panhard attaches to your chassis, but if it were made longer than the panhard bar would be in a much more favorable position.
See pic below:
Here you see the panhard is absolutely as long as the chassis will allow, is nearly parallel with the axle and also has provisions to adjust the roll center.

don't race, don't need to
That pic above has his suspension in full rebound, making the angle exaggerated, no? Still, looks like he attached to the center of the crossmember mounts or old diff mount, giving short arc radius and extra lateral movement like damon mentions. I asked this question wayyy in the beginning exactly because of Damons reasoning. That thing's gonna walk at squat and again at rebound. Still, neat to see a full drag race prep suspension on an FD. Keep it up...

regardless of how he sets it up, a panhard bar totally sucks for locating the rear end. that's why no one ever uses them for racing anymore. everyone either uses a diagonal link or a wishbone.
