At the moment I'm working not so much on cars but on more excel based tools so I can 'spit out' cars much quicker and easier.
This will be used to make the faster cars from GTL, the gtc 76 class with BMW's, 911s, 906, Ford Capri, Corvette.. If that goes well, and the tools work, it might be that eventually the other classes in GTL will also be created using these tools and some of my views on cars.
These cars are quite good fun with often 300+ horsepower and 1100ish kg and some sort of grip from slicks but not too much. They are a bit more raw regarding torque curves and dampers. The experience sofar is that it will be quite an entertaining drive with plenty of 'movement' in the cars.
While rFactor certainly isn't ultra realistic, it seems simply going for realish numbers leads to cars that are fairly easy to mess around with (not to mention fun!) but getting those laptimes down is quite a challenge.
I hope it'll turn out well!
