I agree with this YT Zygrene

yep. the 'burnt oil' indicator he says himself makes me especially curious as far as what change schedule he was working off of.

Says he has changed it 6 times though.

There will not [likely] be follow-up from this individual. They've chosen to move on from the twins and most likely back to another platform they have had years of experience with prior to trying out this platform.

I have 9 HPDEs on my car with just over 4,000 miles on the ODO and no mods to the engine/cooling. I'm using different oil and more frequent change intervals and do actively monitor temps as I lap. I don't consider this the best approach, but it's the one I'm taking until I decide and find suitable hardware.

While I think the best route for track junkies is prevention - oil cooler - it's my general rule to prepare myself for certain costs associated with participating in motorsport, and to never just assume warranty has your back.

It's a $30K car with not all that much of a profit margin for the OEM. This is a lot of money for a lot of people and while I wouldn't want anyone to be discouraged from experiencing HPDE or other motorsports, these are machines, built to a budget and with fluids and maintenance schedules rated for commuter type use. If you're going to modify the rest of the car and push it hard often, you're rolling the dice if you're not taking added measures to protect the engine and other components. The GR Cup series and cars that will be landing next year will be something to closely follow.

THANK YOU!

There are reasons that even with their very expensive custom built engines professional racing teams have at least one spare ready to go at all times.
You consistently push any machine to the limit and eventually you are going to exceed it's design abilities. As you said proper maintenance for the type of use will help extend that period but it can still happen.

I have 0 worries about this. Don't track it, it's just my fun daily to get to work and back. If it blows it blows. 5 year warranty in place. 0% chance I will own it that long anyways so just enjoy it as much as I can until I get bored and move onto something else.

I think it's also important to recognize the difference of 1 or 2 track days a year and 20. I would also consider track driving significantly harder on a car than autocross. SOME people seem to lump it all into one group. A new sports car should be able to mechanically take a track day without a ton of issues. Maybe some heat management problems, especially with turbo cars, I could see as acceptable. I still wouldn't expect a new car to have major drivetrain issues after 20 track days, but I also would hope that someone doing 20 track days a year, isn't using their daily driver, and has accepted that these things can happen.

I want to say that a stock BP in a Miata is considered a 200 hour motor for track work, and I would lump an 86 in the same track-ready expectation as a Miata. Hell, I recently did a track day at VIR in a 250k mile Miata with its totally original drivetrain, and it didn't complain one bit.

There was a comment on it by the Chief Engineer during the GR86 release, he stated they know about the RTV issue but because of the 5 sides in the pickup grill they don't think it would be an issue.

Trying to find the particular article that mentioned that conversation, will update when I do.

For the sake of simplicity we can say there are two categories. One is "normal" street driving and the other is "performance" driving. Of course the reality is that there are many sub categories of each of these and some may beat the car up more on the street or autocross than somebody else on a full fledged track day but a line needs to be drawn someplace and the Toyota warranty phrasing has done that.
There is no way to say that it should be good for 2 or 20 track days. When pushing the car to it's limits one small mistake can take out an engine in the first few seconds of the very first lap. Or it could just keep going and going no matter what you do to it.
It is an inexpensive car designed for the street but given some track abilities not a over built race car that can be driven on the street. These are two totally different things. You totally nailed it that people using it as a track car on a regular basis should be prepared for issues.
