My wife has taken over my 16 viper Se this year and we cant seem to get it set up to her liking.
She is complaining about the steering push and ski lift in the corners.
I installed the BOP MPS system for her as well in order to reduce steering effort. Was planning on a cat ski upgrade as well but figured I should try to adjust the front skid spring and shocks first.
Her weight is probably around 140 lbs with gear .
Question is what should we be running for shock PSI and how many threads showing on the front spring ?
I know all about guys changing out their springs but I just want to deal with what he have for now.

You have air shocks on front? Run 60-65psi at 70deg off ground. Push with Tuners? unless hardpack or she slows down just need new skis.

Yes fox shocks in the front. I am wondering about the shock and spring set up in the skid as well.
I am aware of the skis I will be changing those to Cat skis.

1 on torsions,1 or 2 on limiters and center spring just so it turns. It’s a half turn adjustment that’s noticeable but with tuners you may never get it. I don’t know. With good skis it’s adjusted till front feels light under throttle. But plants and turns with brake or lifting or even just getting forward. Very easy to accomplish. Get the skis.

Just to ad to the above comments,
IMO every procross should have the 6 position racewerx adjuster to replace the factory 3 position. You’ll be surprised on how much the skid responds to the fine adjustments.
Very cool product.
