Right now Ripp is. I think it has the best chance of doing what I want. A combo of no boost when I crawl but a nice linear torque curve on the street or on the sand dunes. I have been talking to them and we are working on some details. I want a cage in this if we are going this fast and am looking at the Poison Spyder one. The shop I use JeePerformanceinc. Does a mod where they tie it back into the windshield. I like that if we are going to be putting that much wind pressure on a slab of glass. Alot of the cages eliminate the windshield braces.
