Handling problem?

[RallySnake]

I enjoy the technical problems posted here. You have a chance to learn something and share experience. I just installed my new Holley Avenger carburetor on my Arntz and am really happy with the added power over my old Quadrajet smog carburetor. To test for fuel supply in severe conditions, I took it out to the local skid pad (mall parking lot) and made some fresh skid marks. I am pleased that the carb supplies power under all conditions but a little worried about the handling. When I push it past the tire's adheasion limits in a right hand turn, it breaks loose evenly and is balanced in a nice four wheel drift. I can easliy control it and straighten the car out when I like. In a left hand turn, however, the rear end is loose and comes around too fast. If I am not quick with opposite steering, the car will spin out.

This testing is done with 28 pounds of pressure in the front tires and 30 in the rears and two people in the car. My car has MG front and Jaguar rear suspension. It has 4 KYB coilovers in the rear and KYB tubes in the front on custom brackets. It has a 1" front swaybar and a 3/4" rear swaybar. The battery in mounted in the right side of the trunk behind the right rear tire. I am thinking that the spring rate in the right rear needs to be softened up, either with the Jaguar upper spring mount or the rear swaybar. OR The right front spring rate needs to be stiffened up. The tires are all the same size Toyo 275/60/15s. I selected these tires in hopes of achieving perfect four wheel drifts. I'm halfway there.

I would appreciate any other ideas or input (other than driver weight adjustments).
