My bad, I mean't 8 main bushes, but the two that wear out alot are the big "butterfly" bushes that are in the front of the trailing arms, hard to get them to last long when driving hard with them fitted BUT they are vital to traction under acceration and braking. The 140 mounts the torque rods in front of the diff so they work both ways. When accelerating, the butterfly bush lets the diff rotate upwards which a small amount and allows the diff to apply force to the torque rods which makes the car squat and you get the best traction possible in a live axle rear suspension. When braking, the diff rotates the other way, pulls on the torque rods, and gives it more brake power at the rear. Works great, but you have to change butterfly bushes often.

140 vs 240 rear: The 240 rear suspension is tougher and last longer, but lacks traction.

I would put your car on flat ground, stick it first, release the hand brake, stick your face under for a look and see where the excess movement is.
