I recently did this swap. I figured it would be a decent little budget-minded suspension upgrade. I procured a set of 1g AWD KYB GR-2's and a set of stock 1g AWD springs. The swap was very straight-forward, everything seemed to bolt on just fine. I had heard rumors about how low the rear gets when you do this swap, and those rumors were definitely true. The rear dropped about 2" altogether. As soon as we finished the rear my friend and I noticed that the spring perch was dangerously close to my inner tire sidewall. I hadn't anticipated this, as most people who do this swap aren't running 225's all around, and some who are running 205's still experience rubbing now and then. Anyway, I had to see what it would do, so I drove it like that. We cut the front springs about one coil each, and that still left the front WAY higher than the rear, and it looked ridiculous. I didn't take any pics of it like this.
Here is a pic of the rear, you can see there is a little groove worn into my tire. It's like this on both sides. It only hit maybe 4 or 5 times total on the drive I took it on, but that was enough to do this. Needless to say, it's not safe to run it like this, there needed to be a solution.
So I threw my stock 14" wheels back on the rear, and drove it back to my buddy's shop. With the 14's on there it didn't rub at all. The solution he came up with was very simple, yet effective. He would make little brackets out of sheet-metal, and weld them to the stock rear beam where the strut normally mounts. That is exactly what he did.
Here you see it completed, with the strut bolted in place. This raised the rear of the car about 1.5", and made it fairly even with the front. Now the spring perch sits well above the top of the tire, and it does not rub anymore. I wish I didn't have to sacrifice the ride height to do this, but I can always use some 1g AWD lowering springs in the future to lower the car down. For now, the car rides fantastic like this, and handles great, but does feel like it's really high off the ground.
Here's how the car sits now:
In summation, I highly recommend this upgrade. The 1g AWD struts and springs are just stiff enough to make the Mirage handle and feel better, while not being so stiff that they jiggle your internal organs loose everywhere you drive. I took the car on a spirited drive this afternoon through some local twisty roads, and it was fun as hell. No bottoming out, no rubbing. For most people, you won't need to weld on the car like I did to raise it up, only those of you running really big wheels/tires on your cars would have to. Now that my car is basically set up for run 1g AWD suspension, there are a lot of options if I decide to get more hardcore with suspension stuff.
