Building off the incredibly successful inagural SpecFit season we are excited to introduce the next iteration of fun per dollar motorsports with the #GRIDLIFE SundaeCup. Both SpecFit and the SundaeCup are 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 & the SundaeCup will run within the TrackBattle series as a sub classification of the Street class. Drivers will run within the same track time allocated for TrackBattle time attack sessions at #GRIDLIFE Events. SundaeCup will be divided into SubClasses based off entries. 4 entries of any similar chassis will automatically create a subclass for that event. IE: SpecFit, FiestaCup, etc.

SundaeCup 2019 RULES


The #GRIDLIFE SundaeCup is designed to be a tight competition in daily drivers with minimum modification. The SundaeCup is designed to allow any vehicle with a factory power to weight ratio of 25:1 to compete against similar vehicles in a daily driver battle within the Time Attack format of the TrackBattle series. All SpecFit and SundaeCup cars 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.



All vehicles competing in the SundaeCup must have a Factory power to weight ratio no greater than 25:1, with driver based off wheel horsepower or 22:1 Based off Crank horsepower  Up to 200 lbs of weight can be added to a safe location, bolted down with grade 8  bolts, ½”, with appropriate washers and backing plates, to “adjust” the power to weight ratio to be  25:1.  Rough power to weight will be scrutineered when necessary , using scales, a dyno, or data acquisition comparison to a known legal car.  


Engine modifications will be restricted to intake tube, filter and exhaust changes only.  Engine internals must be OEM. No forced induction.  If an engine is suspected to be modified, Gridlife reserves the right to have it tested on a chassis dyno and inspect internals with an inspection camera.
