Art,
I have the IRS and it's been great! Never had solid axle 'cause I don't like the feel. IRS handles great, rides great, tracks great, auto-x's great and is just plain great!!

Really, it does need some work to get it to the feel you want. I have front and rear sway bars (rear a must) and Koni adjustables all around. Every bit of work and testing I've put into the chassis has been rewarded back to me. As for toughness, it handles my setup fine at 350hp and I know of some pushing 500hp with sucess.

No vibration at all. The stock ride alone is very comfortable for trips and just driving a little spirited once in awhile.

I'm not using the quad shocks and have no big issues with wheel hop. I have a 3.27 ratio.
