With the limited flex of a unibody constructed vehicle & the ridgid swingarm I made that is supported by the stock spring-struts in their 'wide' stock locations... I don't believe there's a stability issue. With so much of the vehicle's weight located over the front powered & steering tires, the rear one basicly holds-up the rear & adds to the brakeing ability of the vehicle. It would never be the prefered design for a road-racer but a fun street toy I believe it will handle what's asked of it.
