The R4 will not be cheap at all if you will rebuild it after every rally because some genius found that with 5 mm larger restrictor it's faster than R5.
I wasn't talking about R4 (we have AP4 and it is working well, still not cheap but cheaper than R5 and with more car variety), I was talking about RGT.

R5 cars are running what, >100hp more than the production cars they are based on? Along with totally different drivetrain etc. While some RGT cars are forced to run >100hp less than the production cars despite being heavier than R5 and only 2wd.

If R5 cars are really so much better then you shouldn't need to castrate a 911 GT3 to beat it.
