      68 Camaro steering problems

      Hi all we just got done building a 68 Camaro and having some steering problems. The car is a Ls with stock steering gear box. When you turn the wheel and apply the drakes the wheel gets very heavy let off the brake and steering gets easy. We took car out for a shake down and the car wants to wander or not center. This is driving us nuts so any help would be great.

      Thanks Ken

      Has the car been aligned recently? You might want to list what brakes, master and suspension you have in your car. Those would help diagnose your problem.

      Was that -.7 camber? Should have been. You could try adding more caster.

      I would try 5 deg caster. Was that toe in or out?

      Hopefully David Pozzi will weigh in.

      5* positive caster is minimum I'd try to achieve. 3* isn't good for the street or any sort of performance driving. Higher caster numbers will help with tracking straight too.

      However, that shouldn't be the cause of the steering getting heavy while braking. Unless your motor isn't making much vacuum and bogging when turning?

      Ok moved it to 4deg caster and that helped but now need to see if we can get different slugs for the up a-arm. We are having to stack to many shims.

      reduce your camber to under .5. You don't need that much camber with as little caster as your running for the street, and reduce your toe to 1/16. That will help reduce your shim count and help increase caster.

      Does the car have power steering?
      Do you have a hydraboost system on it?
      What size front tires?
      67 Camaro RS that will be faster than anything Mary owns.

      The braking-heavy steering sounds like a hydroboost problem I was having for a while in my swap.
      Are we all sure it doesn't have hydroboost?

      Update We replaced the power gear box installed ride tech tru turn and all the rest of the linkage with new. This was a big improvement. Still having a problem with steering not wanting to center. The wandering is gone. We set the front end up with -.4 camber and 2deg caster with 1/8 toe in. This is what Chris Alston guys said to set there front end at. Alston a-arms and coil overs stock frame. Tires are 245/35/18
      The car does not have a hydro boost. Also can't figure out how to do pics.

      2 deg caster is not enough to center the steering. It will be more neutral. reduce your camber some more and increase your caster to 4 deg min.

      If the control arms are stock, you'd be lucky to get 2 deg out of them (if they're anything like 2nd gens)

      I'm actually running about 6 deg caster on mine with my aftermarket uppers. It was a phenomenal improvement in pretty much everything about the front end (especially the self-centering at speed).

      umm no! run 4-5 degrees positive caster (more if you can), .5 - 1 degree negative camber & 1/8" Toe in,,,, I don't know what Alston thinks your driving? 2 deg caster is factory,
