I had to replace the primary on my '98 last season and bought a used Viper one complete,so I put my tuning components in it and bolted it up.So now I have a set of weights,rollers and a spring sitting in my parts bin and I figured I'd ask if Viper weights are any good at all for an application in an SRX,for trail or racing? If these are of any use to maybe a piped V Max or something?
