Found a new class that fits my car perfectly. It's called Street Touring X or STX. It's a modified version of Street Touring. It's suppose to be for 4 seater cars with engine up to 5.1 Liter NA or 2.0 Liters Forced Induction. These are the basic rules:

*Upto 5.1 Liters NA or upto 2.0 liters Forced Induction
*High Flow Catalytic Converter allowed
*2WD cars may use aftermarket LSD
*Alternate motor mounts allowed
*225mm maximum Tire width
*7.5" max width wheels
*Emissions Legal intake and exhuast
*4 or more passenger seats
*Street tires with treadwear rating of 140 or higher
*Bolt on suspension upgrades.

Woohoo my car fits into those categories. Supposedly this class if for mustangs and turbocharged Eclipses/Talons. So if your car has specs similar to mine STX is the way to go! ^_^
