Oh yes, big time. But that was also predictable.
In response I got skinnier tires for it, which improved lateral stability quite a bit. The stock 325s don't play well with 9-inch rims on the road, the narrowest the OE tire is approved for.
Also, installing a 7/8" inch rear anti sway bar helped a lot. Unlike regular 1500s, there's nothing in the rear on a TRX.
Is it stupid to try making a TRX handle well in the curves? Maybe. But while it'd deal with running off the road much better than would a Challenger or 'Hawk, I still prefer staying on the road if possible.
Nope.
