MKII MR2 Rear Upper Suspension Mount

I track my car. I noticed in the rain that the car was self-steering at the rear depending on how much throttle was applied, and which way the car was loaded. When checking out the rear end of the car in the garage I noticed there was play at the top of the coilover (KW V3s that use the stock strut mount). I could push on the nut at the top of the strut with a screwdriver and move it about 1/2? laterally! I replaced the strut top mounts with these and fixed that issue! Fairly easy install that required removing the strut from the car (easy with coilovers), but does require an alignment afterwards.
