One of the biggest issues with shocks on Vipers is the relatively little (couple inches) amount of travel the rear shocks have to control movement in this very powerful car.
If you look at your shocks, they travel in a very narrow range, and must perform at a very high level to provide both a smooth, and controlled ride.
Most of the lower priced shocks have no hope of providing this level of control. They tend to ride rough, and exhibit a pogo stick effect, even at normal highway speeds. At race tracks this can put even very experienced drivers into the wall. Novice drivers never see it coming.
KW's have a pretty good reputation in the high performance world, but in my 09 they failed to control the rear suspension enough to garner confidence. They felt all bound up, and road rough, and still bounced around on rough corners.
Motons and Penske were the solution to offering great control and ride quality, however they were priced at the top of the market.
The latest Motion Control Suspensions (MCS) are the latest offering for those wanting to both precisely lower their cars, have a great well damped ride, and have a car that hugs the road with great control. Coming around a corner and going full throttle simply launches you down the road with these shocks, even under bumpy conditions.
Priced at just over $3,000 they have become the go to shocks that check all the important boxes, but remain affordable to many.
Serious racers will go even more upscale with remote reservoirs and multiple adjustments, however for those who mainly use their Vipers on the street, but still want occasional track control, these are becoming a great choice.
