Group 5 Race Series 2015

This weekend will see the first race of the Group 5 series at the track.  This is the second time this series has been run at the track with the first series being 2013 with eight racers fighting for the top of the podium.

One of the best things about this race is the option for the racers to run a Racer Sideways model (basically Racer plastic body with all Slot It internals) making it easy for any racer to purchase a car, do some simple modifications and have a race winner. You could also use your car building skills to build a custom car using any Group 5 body mated to any plastic chassis you can get to work.

Here is a picture of the eight cars that competed in the first Group 5 series in 2013.  Four of these cars are Racer Sideways and four are custom.

Here is a picture of the bottom of all the cars and what the different set ups looked like in 2013.  As you can see there are many different set ups and many different ways to build a winner.

Good luck to everyone competing in this race series.
