here is something I have learned when i have dabbled into mod. I run stock at the large events I go to, but I practice with mod when im club racing or just...well practicing. I have found that in the infield a mod car is no faster than a stock car. the only advantage is on straights and sweepers. If you blow a line with a mod it will only make you slower than taking the correct line in stock. One other thing I would do when getting into mod is use say a 13 or 12 turn V2. I do this because it is pretty close in speed to a 19 turn, but with the v2s you can run them much longer than a 19 turn which needs new brushes every 2 runs(except for those siver trinity brushes)I think I ran my v2 for 8-9 packs in 12th scale before i noticed reduced performance.
