GW makes good quality stuff but the geometry provided by the B-body spindles leaves a lot to be desired in terms of steering ratio, bump steer, and ackermann. It does work (only in terms of providing a more favorable camber curve) but it's not an ideal setup-- you get three negatives for the one gain. I run it right now (wanna buy it? LOL!) but plan on upgrading it soon.

As Derek said, best bets *right now* is to use stock spindles with the Howe tall ball joints, or for more money Marcus's G5 setup with modded C5 'Vette spindles, or wait a bit longer (probably about January) for the packages using the new ATS spindle.

You can still use the GW lower arms (even the uppers) though with any of the above setups; the GW arms are super beefy and good quality.

As far as the rear, best "off the shelf" option currently would be the GW TBC-4 lower rears or Currie Currietrac lower rears paired with Edelbrock or Currie upper arms. You aren't going to to much better than that with off the shelf parts and maintain the factory 4-link. If you want to do a little fab, you can make your own upper and lower arms with spherical joints and use the Wolfe Racecraft spherical joints in the upper rear end. There are a lot of better options out there but you're getting into cut-n-weld territory-- how far do you want to go?

I can't offer much in the way of spring suggestion for your application as all my knowledge comes from a car with an SBC over the nose.
