" From: farna@xxxxxxx " " " You'll also need to tighten up the rear springs. Either add a leaf or " use one of the short "half leaf" bolt on stiffeners. Also add a panhard " rod or Watt's link to control sideways movement -- yes, even with leaf " springs. A nice four link would be even better. A 1/2"-3/4" sway bar " would be a good idea also. You don't want the rear as stiff as the front " though, it will handle funny then! the rule of thumb for camaros, with a generally similar geometry to '70s amcs, is fronts 50% stiffer than rears. " One more thing -- get wheel weight down! Weld Draglite wheels or similar, " and lighter calipers. I've been exploring the lighter caliper bit. There " are aluminum replacements for the 82-83 style Concord/Spirit GM calipers, " but they state "for off road use only". They are ISCA certified for " racing though. Speedway carries them (www.speedwaymotors.com). I wonder " why not for street use when they are cetified for road racing and circle " track? That's got to be harder use! that just means they're not dot [or whatever] certified for road use. racing use is harder, but they get more maintenance. snow/salt corrosion isn't a problem for instance. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought
