My wifes ATX tC has almost NO body lean - hence why I was impressed. Remember I drive a fully modded SVT, so impressing me with a off-the-lot car takes a LOT!
Makes sense if the ATX comes with a 22mm bar. Tony, I would think that you could swap the 22mm bar from the ATX into your MTX and that's a great improvement right there.
Also I feel like the shock/springs are pretty firm - not that they couldn't be improved on, but I'll tell you this it handles better than my SVT did new.
