Maybe compaired to the Subarus I really dont know but it does seem you need to upgrade a lot of areas to make them at least reliable and track worthy as a race car. Even cars doing track days have issues with PTU, engine oil, and engine overheating and the brakes only last around 2 track days or sometimes even less before the seals are toast. They do make better aftermarket seals which can tollerate track days but its just an indication that the car isnt like a modern superbike for example that you can roll off the showroom floor run it in and it will take a thrashing at the track and have zero issue mechanically. Wasnt the RS at Bathurst this year way behind due to losing boost or something?Maybe, but I doubt it is much worse that the Evos and Subarus that it was running against. They also completed a full season last year, were really fast, and aside from the transmission issue? at the tail end of the 6h Bathurst the RS seemed pretty reliable.
Just postulating on the cost benifit of an RS as a race car, any others out there with comparitive knowledge about this or have I got the reasoning completely wrong?
