NOTE: I am not trying to adapt a non-F-Body spindle to my car. It is simply a question that has come up in research for other things.


are there OE spindles out there that have the tie rod and control arm mounting points in a place that would allow them to be mounted to the third generation FBody?

if yes, which?

was looking through spindle pictures on google trying to see if anyone makes a decent aftermarket street spindle and saw a C4? spindle and tht question came into my head

 

no.. not unless you add an upper control arm.
the easiest route to take if you went that route would be G body stuff, since it's based off that, anyways.. but of course 77-96 B body spindles are an upgrade for G bodies which allows you to pick up 12" brakes from any junkyard in the country, so you might as well work around that...

 

You'd have alot better chance manipulating the steering system rather than the spindles.

What could be done? This same box (pitman and Idler) as well as S10 spindles are used ont he NASCAR Supertrucks. WHen they jigged the chassis builds, they narrowed the gap betweent he box and the idler in mount width whereas to have the tireods hange off just below the drilled out tapers of the pitman and idler. The drag link is dual posted with upper and lower rodeend link assemblies laterally sandwinching the pitman and idler. The bolts going down through are long enough to ajoin the tierods in lower vertical- which means the box and idelr also need to be mounted rearward as well to improve geometry swing which increases the ackerman.

This helps reduice bumpsteer with massive caster, as well as problems with having to extend the outer tierod downward when using extended ball joints. Its alot of fabbing, but completely doable I know on My V6 car because I had ALOT of space for this. I had a rear sterring box brace the V8 cars could not do so I am not certain if this could be done also or not, I never checked the concept on a V8 car.

This is another one of my long lost secret ideas I have never shared until now. I am never buidlding another 3rd gen so I figure I would share them now. It is one major fix to the poor engineering aspects of these cars- don;t get me wrong, the platform is great, it just lacks in a few troubled areas that aftermarket stuff has helped fix over the years- this ackerman issue has always plagued the car.

 

Here's a pic of my rear steering box brace and the room I had in the engine bay. I could stand in there between the motor and the radiator

if you could build a 'strut mount' for the spindle you could probably do it. eg: figuring out how to take advantage of that top mount and keep the same geometry.

slicktrack, interesting infor.
