1.Better car balancing (thru tuning and the pp system) for online racing. There still are cars that dominate in their respective PP levels, leaving the racing field scattered with one make without any real variance. This is terrible for those of us who like to race a 'unique' car, or a car that isn't frequently seen online, or those of use that like to use a car that takes a lot of tuning knowledge to do well with (me).
2.More tuning options, especially front downforce options (Major balance issue online - cars with the 'extension' aero or with adjustable front downforce get a huge advantage).
3.Well executed drag content - Reaction times, clutch gear shifts, bracket racing, inconsistencies in performance dependent on environment conditions, and drag tuning options (High risk AFR resulting in a popped piston or other dmg if not done dialed in, etc). Dyno tuning would be absolutely great for this.
4. High horsepower cars actually SOUNDING like high horsepower cars. The sounds are quite pathetic.
5. More tracks.
