I'm not seeing the self evident increase in cornering speeds..why? Lower sidewalls are not necessarily better when using (semi) slicks. I would be more carefull about making blanket statements like these.

You right its very vehicle dependant , depending on the vehicle power / weight / chassis design / aerodynamics etc etc there can be a point which larger profile tyres are faster due to there better heat dissipation and load torque transfering absorption ability.

But maybe we are way off topic from a ae86 , its light so overheating small area low profile tyres shouldn't be a issue unless chassis set up produces it. Traction effort / transferring the torque shouldn't be a issue to a limit as most cars just have small engines , the four link also is great for straight line traction if the correct angles are set. And aero the car is a upside down wing in shape so downforce is out of the question.

So any area decrease in side wall will only increase stiffness , resulting in everything from laterial stability to less distortion under heavy loads like braking

From memory Kai power , KMS , Pro sprits etc have all found 17" faster on the track but 17" tyres where instantly banned from N2 racing.
