I-Moto Racing 2004 Acura TSX - Ain't It Grand

Being Grandiose

The Grand American Road Racing Association (www.grandamerican.com) was founded with rules aimed at keeping costs down and competitors evenly matched. Grand American racing is actually comprised of two distinct series, each with two separate classes. The big dogs run in the Rolex Sports Car Series and the biggest dogs of them all are the purpose-built Daytona Prototypes (DP). The production-based Grand Touring (GT) cars may look more like a high-end sports car fresh off the showroom floor but they flex some of the same tech as their DP siblings.

The Grand Am Cup Series is where the true showroom stockers come to play. The Grand Sport (GS) class is home to the higher-displacement cars and the Street Tuner (ST) class is all about the Super Street rides only without the Lambo doors and JDM headlight conversions. In order to ensure parity, exact specs vary from model to model. Here is a rough breakdown of the classes:

CLASS	CARS	ENGINES	HP	MIN. WEIGHT (lb)	TOP SPEED (mph)
DP	purpose-built	mostly 4-5L V8 and 3.8 liter flat-six	500	2,150-2,275	185
GT	Corvette, F360, GT3,GTO, M3, RX-8	V8, flat-six, three-rotor	390-450	2,500-2,700	170
GS	CTS-V, GTO, Mustang, M3, NSX, 350Z, 911	V8, flat-six, two-rotor	350-405	2,730-3,250	160
ST	Cobalt SS, IS 300, Mini Cooper S, RSX, SRT4, TSX, 3-Series	four-, six-cylinder	170-240	2,200-2,925	135
