The heat checking is from thermal fatigue, I wouldn't think having them turned is helpful, from a safety standpoint. |

I've never heard of it either. I'd be surprised if it weren't possible, as I can't think of any reason for that. Of course, there may be something I haven't considered. I've never owned two piece rotors.

Aero questions. Im going to get a wing for my car, the rear is really loose, its fast but its scary driving specially on long sweepers. I dont want to turn the oversteer into understeer and my suspension isnt adjustable (its stock actually). Should I worry about a front splitter or air dam at first or should I just try the wing by itself? Im affraid the wing might lift the front without any aero that transform all of that happy tail oversteer into understeer.
Also, im not only doing it because I find it scary, im really chicken anyways so that probably wont change but I think I can find more time if I can have some more late apexes with early gas applications. I find myself having to give up on some late apexes because the rear will slide out at turn in, I can probably trail brake some more too, currently lifting off brakes completely halfway between turn in and apex, I could probably trail brake all the way to the apex with a wing, allowing me to brake later. Edit: alignement is -3 camber up front, -2 camber rear, 0 toe all around. Edit 2: more info, 28k miles on stock dampers with around 15 track days (2-3 hours of track time per day). Surface is tarmac not asphalt so it is smooth, but no rubbery smooth. Tires are 225/45/17 Maxxis RC1. So far I have tried 38, 35 and 32 hot pressures on them. 32 produced the fastest times and better turn in. Last edited by Icecreamtruk; 06-06-2016 at 01:41 PM. |

"...the rear is really loose..."
"...my suspension isnt adjustable (its stock actually)..." Something doesn't add up. Before getting a wing figure out what is wrong with the car right now. If you're on stock suspension and the car is really loose there is something that needs to be address before aero. |

Camber? Ride height - are you slammed if you say that alignment is far from stock? Miles on your oem dampers (street vs track)? Tire type/size/age/miles/thread left/hot pressures? Tires same type/size front and back? Rim size front/rear? Number of hours you've had on track/ax to date? Road surface smooth in the sweepers where you brake loose? Something could be shot for you to experience sudden oversteer or you may simply find oversteer uncomfortable to deal with. You may get better advice if you offer more information.

It is not sudden oversteer, its stable, predictable, always there at every turn in oversteer. The car has no understeer on it at turn entry, at all, ever, it goes straigh to oversteer. The only way I can kind of experience understeer is at corner exit on slow corners if I stat accelerating too soon. |

If it happens at every turn you need to address something other than aero. That will only make a significant difference in high speed turns.

Try going into a corner too fast. You'll understeer, at least at first.

For the pedal dance, I have been doing it, I dont think the electronics would allow for so much slip angle even in "off" mode. |

You've spent some time on track and your alignment and pressures look ok. FR-S has some oversteer built from the factory. Heard that RC1 like clean lines so smooth inputs near the limit can make a difference. Does it behave the same on both left and right turns? May be worth having somebody familiar with twins inspect the suspension, also a more experienced twin driver take a few laps with your car on track, if that's an option. To each their own but I wouldn't touch aero before upgrading dampers, and perhaps some bushings if you want a more track focused car. |

Thanks everyone for the input, seems like aero is not really the solution yet. |
