Hi Joe.
The stock front bar is less than 3/4", I think it's 11/16". The first
upgrade to a TR6 suspension is the 3/4" bar or for the really serious
folks a 7/8" bar.
Adding a rear bar with the stock front swaybar will make the car very
tail-happy.
I run the street car with a 7/8" front bar and a 3/4" rear bar (addco). It
corners pretty flat and you can rotate the car with the throttle fairly
easily. I would say that the car is balanced with a very tiny amount of
understeer on turn-in. This is a good thing. The addco setup is not
adjustable. This is perfect for the "tuner" who doesn't have access to a
skid pad or other means to "tune" the bars... you bolt 'em in and go
driving. In some ways this could be considered perfect.
BUT, in the wet, the car is very easy to over-rotate. This is not good for
average drivers. I don't have a problem with it and actually find it fun
to drive, but I have pay 100% attention to the car in the wet.
The GoodParts bars are 3/4" front and rear. The advantage of this setup is
that the rear bar is tuneable. So, if the car exhibits oversteer in
certain conditions, you can soften the rear bar to balance the car out. So
this setup is ideal for someone that likes to tweak the suspension to the
conditions.
I'm not sure what your last statement means, but it seems to imply that
the rear shock rebound valving is wrong (or the shocks are blown). Make
sure that the shocks give resistance in both directions and that there is
no play in the shock mounting. I'd also look for cracks in the mounts and
consider harder bushing material for the shocks to eliminate play there.
Have fun deciding!
