In response to the effect of the rear subframe bushings, these things are AWESOME. Install takes more time than had been previously mentioned earlier in the thread (realistically, with an 18 year old car the original bushings are going to be completely shot and are a bitch to remove if you don't have a torch) but is still fairly simple. I did it on jack stands in the garage and installed two new ebrake cables, and sandblasted all of the nuts and bolts that were removed before reinstallation and the total time actually spent working on the vehicle was probably closer to 8 hours. Note, I wasn't hurrying myself too much, but you have to remember that while working on jack stands by yourself, removing the exhaust, driveshaft, and rear subframe can be a bit of a hassle if you're trying not to destroy anything including avoiding snapping/stripping old rusted nuts and bolts.
But back to the good stuff. These bushings made a world of difference on my car. Just by installing these it stiffened up the rear so much compared to the original bushings, it feels like a whole new car. I would STRONGLY advise use of these bushings to anyone and everyone who owns one of these cars.
