So what the heck is it, you ask?

The car you’re about to climb into is already competing in the Radical Australia Cup so make no doubt about it, it is a REAL and full blown race car you’re getting into.

Its fast and handles brilliantly … but like most things dont take other peoples word for it … the only way to REALLY appreciate this kind of vehicle is to get Onboard… and take a few hot laps to experience the thrill, excitement and be in awe of its capabilities.

The Radical SR3 is an amazing piece of kit.
