Tarret Bar and Set up Help Needed Options

[Dave Bell]

Finally got around to putting the Tarret Bar I picked up via the infamous Group buy.

Old Set up: Stock Sway and 140's on rear = tail happy in tight turns.

New Set up: Full soft on the Tarret sway and 140's on the rear and the car pushes some now.

Anybody with experience with these bars? It is advertized as equivalent to a 22mm solid bar in stiffness. That would be 80% stiffer than a 19mm solid bar. My guess is they used a roughly 1 inch O.D. bar with a 5mm thickness to get the 22mm equivalent??... just a guesstimate since the welded ends don't let you measure tube thickness.

I am thinking of stepping up to 180 springs in the rear but want to see what other's might recommend. Car rides fine with Koni red's all the way around and I don't think I will have any disappointment with a stiffer rear.... after having old KYB's in the rear to start with... almost anything feels like a smoother ride.
