cornering-on-rails feeling

[paulca]

There is definately a point when the "rear wheel drive" nature starts to surface in the car's feel. It is way, way before you actually get to sliding.

There is one corner on my way home from work that has "shell grip" on it (crushed sea shells rolled into the tarmac) cause it used to be an accident black spot. So it has massive grip. I typically fall way back from the car in front, pop it into 3rd and nail it round it apexing at 70mph, exiting at 80+. The odd thing is how the car feel changes if you need to get off the power mid bend, or worse brake mid bend. The car is NOT sliding, but the geometry (or something) changes dramatically. Typically on the power it's very pointy, feels like it's actively trying to turn into the corner, come off the power or onto the brakes and it tries to widen the turn. Remember, NOT sliding, NOT understeer/oversteer, just the suspension geometry, diff, and RWD. It's quite odd, but I love it to bits.

That sounded way too sexual.

I think you need to see a therapist. Just sayin'.

I don't need to pay somebody to tell me I'm crazy!

Not odd.. it's weight transfer. The car is trying to understeer because you have more weight on the front tires and they need more slip angle to achieve the same direction.

You need to go back to physics 101. More weight = more grip = less under steer.

One thing I love about this car is when I go into a corner I get the sensation of extreme downforce and stability when I go into a corner at a higher rate of speed that I was supposed to be driving 35mph at. That might be the feeling you're referring too and I feel a lot of it has to do with the CoG mixed with how balance the car is.

Look at a tire curve before you start throwing daggers. All I said was that the car was TRYING to understeer just as you said yourself, "It's trying to widen the turn..." Do you know what a slip angle is and how a vehicle functions and turns? Your front tires are essentially ALWAYS slipping when your turning, and since you increased the weight on them, you need to increase the slip angle to get the same direction. Physics 101 doesn't even come close to touching the characteristics of tires.

Definitely nope. BRZ has the best handling.

cornering on rails
am i doing this right?

[notout86]

Would anyone like to just TRY my 38 front / 34 rear tyre/tire pressure settings and send comments? I am on the o.e. tyres/tires.
Those settings are dead accurate with a calibrated gauge at near sea level and temperature around 20Celcius and cold tyres/tires (not that that it makes much difference if these are varied).
