I am converting a trophy kart elite to a personal fun machine. My kids race the karts and I want to be able to drive with them and help them learn to be better drivers. I bought a TK elite (randy's cabinet car) and it has extensive rear suspension mods making the chain very difficult to manage and it only has 8inches rear travel. I am putting a Raptor 660 motor in it and will be moving the drivers compartment back about 4 inches to make more room. I will be running some kind of IRS in the rear to make more room and allow the motor to sit back in the car. I am considering a dual A-arm setup, trailing arms, and the "three link" like the Redline Revolt uses. I am looking for something that whold work best in the dezert and short course and not just good for one or the other. I race in Whiplash with my rhino and could short course the car or run it in a dezert event like Snowflake where top speed is the name of the game. I have not been able to find out what the antisquat numbers would be for the IRS systems. What would you guys recommend and why? I have the resourses to build whatever I need to so I am not limited by off the shelf parts. Here is a pic of the Revolt's suspension for reference.
