Car Class DefinitionsTo help alleviate some confusion over the years concerning your Mustangs Classification we are going to list the basics to help you ascertain the placement of your vehicle for the 2019 Mustang Roundup. Also included will be an area to list changes/modifications etc. on your Mustang so we can alert you ahead of the event if you will be in a different group than you selected.
Stock Class1. Tires must be street legal and can have a Treadwear as low as 200, but no lower (similar to SCCA and NASA rules)2. Modifications will be quite minor, though we will allow Camber Plates to help preserve tire wear. Other allowable Options will be Cat-Back exhaust systems, shock changes, brake pads, cold air intakes, and short throw shift kits.3. No headers, no cat deletes, no PCM changes, etc. are allowed.
Modified Class1. All modifications listed above, plus one can run DOT Competition Tires – Treadwear ratings under 200.2. Headers, PCM change, spoilers and splitters (no wings) , no internal engine modifications . Supercharged cars will be viewed on a case to case basis and some will need to go to the Outlaw Modified Class
Outlaw Modified1. Substantial engine modifications resulting in large HP increases, extensive weight reductions, wings , major suspension changes , flares, and DOT competition tires allowed. All above Mods to two previous classes are okay, too.
Race Class1. Boss 302S, Boss 302R, FR500, or home built regardless of year. If cars have substantial weight reductions, roll cages, and more they will likely be classified in this Class even if you do not personally race the car in Sanctioned Events.
GT 350 Class1.Follow the Stock rules and make sure you stay with the stock tires or use others with a 200 Treadwear rating or higher.
GT 350R Class1.You can run the Pilot Sport Cup 2s or other tires that have a lower than 200 Treadwear rating, just understand that going to a tire than has a 200 or higher rating will not move you to the GT 350 Class.
Special Note: Due the extensive use of used World Challenge Pirelli Slicks with Mustang Roundup Competitors, we will still allow these in all Classes except the Stock ones and the GT 350 Class. This is counter to what the main Sanctioning Bodies have changed to, as this tire normally has a point penalty or Class upgrade due to their wearability and grip.
