Why is everybody trying to change this car so much.
The car is awesome. Run the car the way it was designed and you will love it. The roll center adjustability is fantastic tuning tool. If you run run the front with the highest roll center and the back with the lowest roll center the car is almost impossible to traction roll on the highest traction imaginable. This car comes with everything you need to go fast in every condition. (maybe with the exception of a very small high bite track where you would want a front diff.) Racing is all about tires choosing the correct shore and diameter for your track conditions.
Just my opinion........... and just wanted to say I love this car. Now it is time to work on my 950R.
