Alignment specs to shoot for at drag strip?

[AlleyCat]

I am putting the front runners on and the drag radials on the rear for the alignment.

Toe - rear 0?
Front ? (High speed stability)

Camber rear 0?
Front? (High speed stability)

Caster. Rear,. as much as possible?
Front. as much as possible?

Any front suspension part I should consider buying for high speed stability?

Reach out to AAD Performance, they have the parts and info you need on this.

AAD does make a great product. $779 for the adjustable ones. They weigh one pound less than stock. So if you are looking for the top notch item that is it.
I however was looking for an alternative fix. I found it with Moog. Kit K100023. They use extremely strong bolts that go into the existing bushings to adjust camber and caster. Through Rock Auto they are less than 14 a piece. I ordered four of them. So I should be able to get the camber to zero now. A Moog tech told me if in any case one side should read positive and one side negative then the cradle needs to be loosened and adjusted. He said that happens a lot with the Chrysler products. I will let everyone know the results within the next few weeks.

I have +.5 degrees rear camber. The idea being...... as the weight transfers initially on the starting line and the rear squats, the camber will move negative. That little bit of positive camber will move to zero when accelerating and that’s what you want for getting power to the track. Toe should be zero because you want the tire pulling straight ahead and not in or out. On the front I just told them to put them as close to factory spec as possible.

The rear is pretty much dialed in with one at zero camber and another one at -.5. Toe is straight. I will now be able to get the front dialed in at pretty much the same specs.
But I think the pushing left is due to my diff. Starting to give out. I wish I could use my dss axles and qa1 with a stronger diff. Without buying an entire 9 inch setup.

Did they replace the 2.62 with a 2.68? 230 mm vs. 195 on the old diff.? 710-750 dollars.
Never mind. The axle ratio is 2.68 and the differential ratio is 2.62. It has always been 230 m.m. in size.

Great thread

We need this same thing for road courses.

Road courses are easy.
Front - 2 deg.
Rear - 1.5
Toe front - small amount toe in 1/32" or so.
Toe rear - 0
Or as close as you can get it. Once you start running soft tires and upping your suspension capability there should be advantage in - 2.5 deg in the front for track only.

What are our OE specs?
