Fabricated A-Body spindle ideas and discussion
This is an honest question Dion. What exactly are you trying to gain by going to all this trouble over using a factory spindle arrangement?
Maybe some background is in order.
I started the project because I wanted to use an LX/LC hub so I could wire up an ABS module from a late model Challenger. I wasn’t looking to add ABS, but was wanting to feed the “stock” speed signal to the PCM so it could run the factory cruise control. This is in the G3 swap car, so this would be with a factory (NGC) PCM.
I pivoted to the idea of S550 hub when I decided I couldn’t trust the bolt pattern on the aftermarket hubs. Regardless of my opinion on what the factory bolt pattern is or is not, the aftermarket hubs are definitely 115mm and that killed using those hubs.
So the number one reason I started the project was wheel speed sensors for cruise control.
I also want a cartridge style bolt on hub. Frankly, I’m not comfortable with 32# brake rotors hanging off the stock spindle pin. Not that it is generally a problem, but since I want tone rings, it makes a ton of sense (to me) to get away from that style spindle and go to something more modern.
In the subsequent time, I have decided I do want to wire up ABS. I believe the system from an 09 or maybe 10 Challenger could be retrofitted, but I think the better plan is a system out of an S197. But that part of the project is for much later.
I also want to engineer in caster. I think the factory designed the original suspension with 1/2 degree negative caster and rolling the spindle back to get about 6 degrees positive caster drops the OTR about 3/4” or so. I suspect that maintaining the designed OTR location by engineering in positive caster will have benefits.
Big brakes are a given as well.
I would also add that I like this kind of stuff.
