The modes in the car have nothing to do with suspension setting unless you have a magnaride car. In a Non-magnaride car, the settings adjust transmission tuning and traction control settings
the kit actually includes both red and black bushings. Red would be for street use and Black would be for the track. The black will transmit a little bit of NVH
Majority of that sway is coming from the lack of bushings provided from the factory in the IRS. Our starter Stop the Hop will fill in the void in those bushing and then come back with the ingenious IRS braces to reinforce the entire subframe. I can gladly get you into the kit with a forum...
Hey Kyle, the kit actually includes both 80 and 90 durometer bushings. The 80 is recommended for all street use as it doesn't induce any NVH/gear whine, where as the 90 durometer suggested for track use will add gear whine. If you give me a call, I will get you a forum discounted price :)...
