Yep- I have the 203. I've run it pretty hard and has held up with everything I've thrown at it.
My front driveshaft wore out the splines in it. It could wobble side to side at the slip part of it by 1/2". Ordered a Tom Woods shaft for that one also. They have 4" of splines instead of around 2" that the stock driveshaft has. And they put a nice rubber CV boot over it to keep crap out.
I bought a set of winter tires (brand new) and the slight vibration is still there. So something in the 203 is doing it I'm guessing. But I'm used to it now.
