I'm all but converted to the GRC from my previous GR86 preference. The only thing I am having trouble predicting is the GR-FOUR systems possibility of overheating on track. I'll be wanting to use this car for everything, including ~6 track days a year. Now, I know there's a lot of predicting and speculation about specifics on the GRC some members don't like here, but if the GRC is unable to run on 15-20 minute track sessions in California weather, I'll likely have to go back to the GR86.
I was hoping to find at least a somewhat definitive answer on the GRY forums, considering the AWD system is the same on the GRC, but I am finding conflicting answers. Many report the overheating issue coming up after donuts and drifting, which I don't care about. Some members say they have no issues with tracking, others also report overheating after a track day. There are plenty of videos on youtube of the overheating message on the screen it just has me worried.
Some remedies I've read about are the larger Cusco diff backing plate, which increases capacity from 500cc to 750cc. Another is heat wrapping a section of the exhaust pipe nearest to the diff/clutch system. And the last is comments from toyota during the unveiling that air will be better routed to aid cooling.
With the above aids, do you think the overheating will be a nonissue? Do we think a cooler might be developed? What do you guys think?
