Reading through this thread i find i funny how many people mention "...how many world titles...." For the beginner or mid level driver looking to step it up, why would you care if a car has won world title? World titles are won in Mod not slower classes. A cars capability and setup window is so different in Mod than slower classes this is a poor way to pick a chassis type. Good example of a car that's superior in Mod on asphalt is the Yokomo. However this car is terrible in stock on carpet.

The question you should be asking is what chassis have won big races in Stock and Super Stock? In the US on carpet there's only 2 cars to mention, Xray and Awesomatix. In fact Awesomatix has won every big race so far in 2014 in the US on carpet. At IIC this year 5 of 10 cars in the Stock A main were Awesomatix.

So look at what surface you'll be running on for the most part and than look at what cars have won 17.5 and 13.5 classes.

Fyi, the Awesomatix doesn't have to cost you a fortune, look for used cars at your local tracks or on RCtech for sale.
