|Notes||The car is almost "undrivable" in standard spec. Huge turbo lag, not enough power (compared to the weight) and overboost time as low as 3S are all contributing to the feeling the car could do much more. On top there's no way you can get into overboost unless you keep the gas pedal to the floor and keep it there (a 1mm lift stops the car). I highly recommend a level 1 chip modification which is widely available.
Some cars (in the series with big turbos) suffer from a mismatch between the synchromeshes of the 3rd and 4th gear. When you push to the red line in 3rd or 4th, gear changes cause loud (and unpleasant) noises. These same cars need a silent-bloc upgrade in order to allow proper tyre wear. These is normally covered by the guaranty.
