72 Dart Swinger 3.6L Pentastar +T5
Front Suspension Redesign
With the engine now running, I've found renewed vigor to get the front end nailed down.
I added a Mustang II front steer spindle to my Dart Suspension 3D model to correct the issues with the Corvette C4 Knuckle I was looking to use. The deal breaker with the C4 was that it required the UCA to be less than 7" long, which made for a fairy steep Camber curve.
I put a M2, 2" Drop Spindle into my assembly and mated it to the 73 B-Body LCA. It's looking much better. The UCA is currently ~9.25" and the Camber curve is much improve. Looks likes it's actually losing camber with 1" dive, which should be good for braking.
I have to double check my model and make sure I have the UCA in the correct spot along with the vehicle "Ride height" ei: ground to Tbar. Then I'll check Bump & Dive with some roll added. I have a new Mustang II spindle with a bolt on steering arm ($100) on its way for mocking up.
NOTE: SPC "Race" UCA are a la carte which is cool. The Weird thing is that when you tally all the pieces on Summit, they wind up being $200 CHEAPER a SET than SPC Mopar arms. Weird.... http://www.spcalignment.com/race
Next step is to decide what sort of power rack to use.
Standard or Center steer.
Standard rack has fewer parts but the Center steer has really long tie rods(smaller arc length for reduced bump steer) and the tie rod mounting point can be moved around quite a bit.
Packaging around the Strut rods and swaybar may be the limiting factor.
Assuming you all know what a Standard R/P looks like, here's the "Center steer" im referring to:
"Stock" tie rod mounting point
Modified Tie rod mounting (note this is also a rear steer vs front steer shown above)
