The wheel hop or often referred to as power hop issue has the tendency to be a touchy subject for some, but understand, it's not a problem that only Chrysler/Dodge is having.
The new Camaro, Corvette, certain year models of Mustangs, and several more are experiencing the same wheel hop issues.
Today's auto makers have a broad range of expectations to live up to as compared to the old school versions of these cars. Back in the day people were concerned about straight line performance. Most of the cars we grew up with and love so much didn't have the best handling features; many didn't even have sway bars, air conditioning, power steering, power brakes, or power anything for a matter of fact.
Take the '70 Challenger for example; it came with extra leaf springs on the passenger's side for big block and Hemi powered cars and the torsion bars were adjusted to somewhat level the car back out. Fast forward to today's Dodge Challenger, Charger, Magnum, and Chrysler 300; The IRS (independent rear suspension) systems used under the rear of these cars is to meet the expectations of modern day muscle car owners.
I don't mean that in a bad way, I enjoy the ride quality offered with IRS, but the solution to wheel hop is a much greater task. It's no longer just a matter of bolting on a set of traction bars. It's a fine balance of controlling the hop while maintaining the ride quality the designer worked so hard to achieve.
