SpecFit is all about bringing motorsports to the masses with a maximum fun per dollar series utilizing affordable daily drivers, a simplified rule set and a balanced field putting focus on the driver vs the build. SpecFit will run within the TrackBattle series as a sub classification of the HPDE+ class. Drivers will run within the same track time allocated for TrackBattle time attack sessions at #GRIDLIFE Events.


SPEC FIT 2017 RULES

Introduction

Spec FitBattle is designed to be a tight competition in adorable little daily driver econoboxes.  These cars handle well with minimal work, and bolt-on modifications deliver minimal extra power. This simplicity, combined with relatively low cost and an extremely useful design make the Fit a good choice for a daily driver track car.  Pairing them with a group of other similar Fits results in incredibly fun tracktime.  Spec FitBattle cars must be within the “spirit of the rules” and any car judged by the TrackBattle staff to be outside the bounds of the “spirit” of the rules will be moved to an appropriate class.  The “spirit of the rules” is a simple, bolt-on street car.
