[FIA GT] FIA/ACO GT regulations

[ger80]

I have a little problem with the GT regs and the performance adjustments which are done in FIA GT and ALMS mostly at the moment.
Is it realy the best way to have regs that make much development on the cars necsesary but adjust them after that?
The adjustments are nescesary because the GT regs define the permitted difference between a road and race car mostly.
Thats all ok, but if there are adjustments which are based on race results or whatever at the end, why the teams have to use such expensive cars?
Think we need regs which are based on technical facts or adjustments only, but not a mix of technical facts, difference road/race car and adjustmensts
Look at GT3, many different cars are racing there. Super GT is another example, there rules are based on technical facts mostly.
