Unfortunately I did a t-motion delete (munster), ZRP spindles, SLP skis, and Exit shocks all around with torsion spring delete at the same time but made for a WAY WAY better ride. Very noticeable improvement sidehilling. Had the ability to compare back and forth from an identical stock sled last season. 5 skidoo riders in my group, 4 2022 expert turbos and 1 expert NA. Everyone that road my sled was blown away with the difference and preferred my sled no question about it.
I feel the biggest change is SLP skis, t-motion delete, and rear torsion spring delete. As a few of the sleds in my group had t-motion delete and ZRP spindles only, I feel just a t-motion delete is a minor improvement for the average rider.
Hoping the Gen 5 solves lots of these limitations the Gen 4 chassis has.
