Passing the Kellymoss GT4R across the scales at Kellymoss found that our modifications resulted in an overall reduction of 240 lbs of weight. This translates to a near 2-second reduction in lap time solely due to reduced weight of the car - a significant win.
Check back for additional testing results as we put the Ultimate Track Car through her paces over the next couple of months.

The result is the Kellymoss GT4R — a fusion of Porsche engineering and Kellymoss ingenuity. Every decision served a singular goal: more grip, more feedback, more connection between driver and machine. From the titanium exhaust that sings like a Cup car to the multilink suspension that glues it to the pavement, every detail was hand-crafted to sharpen performance and shed
weight, meaningfully increasing your speed.
The re-sculpted body generates serious downforce, wrapping the car in carbon that’s both
functional and beautiful.
