The FZR use to have serious tire ware and fuel use issues. Thats been fixed. Now the FZR is faster, the result of better physics over all which now just bring its advantages to light. It has its weight on the drive tires. It has a rear weight bias like an open wheel car. It has less torque and the same HP as the other GTRs, and has a higher redline. Its major advantage is simple, its basic design and lack of turbo lag combine to make it a faster car overall.
It will be nearly imposible to ballance the class in all situations, even if the cars were equal in terms of weight, power and engine size the FXR would run away as it has better grip out of corners. There is a reason why in most racing classes in the real world the cars are very similar in design and power. Its easier to ballance a class when you do not need to consider fundemental differences. Audi has been baned from nearly every class because its AWD gives it a clear advantage in most conditions.
The only thing i can think of to ballance this class is to rip the little turbo charged 4 cylinder engines out of the XRR and FXR and drop in bigger engines. The XRR can get either a V6 or I6 and the FXR should get the same Flat 6 as the FZR. Then they will be on more even footing and ballancing the class from there will be easier. This removes one of the fundimental design differences. Displacement vs Forced Induction. Neither the XRR or FXR have the low end torque to get out of the whole with gusto, like the FZR.
I race the FZR because I like the look, the drive layout and the lack of forced induction, but I woudl really like to see the other cars be on more equal footing as races are more interesting when there are different cars to choose from.
of course this wont be untill the next noncompatible patch coming soon..
i was actually thinking RBR myself vs fxr and xrr but not the lxr and rar (damn the RAR would be sweet!)
