I am once again using my 93 RM Wagon as the daily driver. Now that I'm using the car for work, I am in the process of pulling the wood grain, debadging, paint and wheels. I am stongly considering 20" Coys. I've had trouble in the past with bending larger diameter cast and alloy wheels. How strong are Coys? I'm told that the are fairly stout. Your thoughts and expreiences?
