Per his responses on Instagram $13,700. That may be the price on this build. Maybe the start a little cheaper if you chose different options...
I personally could care less on what anyone "calls" it when a quad kit is installed. All I know is that this type of setup will just kill any Slingshot in the typical stock 3 wheel configuration. This type of setup is not for someone that worries about classifications. To appreciate this, you really need to understand the performance and how it relates to other very fast and expensive vehicles. It is a legitimate go cart with 4 wheels that you can drive legally on the street and will likely embarrass Arial Atoms, KTM X-Bows, and other super cars in performance metrics.
I have one of the fastest, if not the fastest, track Slingshots in the country. I am quite literally out of things to add to it that would make it faster on a track in a 3-wheeled configuration. I like the looks of a 3-wheeled Slingshot better, but you never get the crazy fast acceleration feeling in a Slingshot because rear traction is such an issue. At some point you just hit a performance wall with 3 wheels, to go any faster you would need to add a quad kit.
Props to Bob and making this kit a reality so people can buy it. For around a $50k budget/build, this is a tremendous value compared to other vehicles with this type of performance.
I know Bob will say I'm being a troll again... that's life, the 4 wheels from what I saw was no better or worse when we were in Colorado last year and @otter hit the guard rail in his "quad" SlingShot! No one in my opinion can argue that @otter aka Tracy is not an excellent engineer and mechanic. He builds and flies his own planes, he has since re-built his sling that he wrecked in Colorado, but I know that even he admitted the 4 wheels did not really contribute or detract from the driving experience. I believe that for the Slingshot to stay a Slingshot it needs to at least be a three wheeled vehicle, close to the body design and lite weight as possible, thus, when I finish off this season of SlingShot events, I will proceed with my quest to build the 1st ALL-Wheel Drive Slingshot with the Subaru WRX turbocharged drivetrain we have!
I just feel that is the next logical step after I did the 1st Honda Powered Sling and proved it is viable and fast, Jamie Roy has taken that concept to the next level with his Honda 2.4K motor build that will debut in MV, and since I don't want to be in that crowded arena of "a Honda....., So?" I'm going to go AWD!
