Thats not what im trying to say at all. I do appreciate you trying to help me though. I will try to explain it in a slightly different way.


With my current set up (stretched 225 in front and 255 in back) when i go into a corner to fast the front tires do not lose grip. They stay firmly planted to the road. At a certain point the rears will lose grip and the tail will slide. In this situation oversteer happens when the rears exceed their max grip. The front tires are never exceeding their max grip and are always staying planted. When the rears let go is what decides when the car starts to oversteer.

now lets assume I kept the same rear tires and put 255 tires on the front as well. Now lets assume i took the same corner at the same speed as mentioned above. Again the front tires would not lose grip and stay planted throughout the turn. The rear tires would lose grip and the car would oversteer at the exact same point they did in the previous example.

In both example the 225 in front and the 255 in front are NOT exceeding their max grip. They are both providing the exact same amount of grip in the front. It is the rear tires that are slipping and since in both examples the rear tires are the same they will lose traction at the exact same time.

In these examples the change of front tires will not make the car oversteer any more or any less.


Also, Happy Turkey Day!!!!!
Just because your car doesn't loose grip, doesn't mean the tires aren't slipping.
Oversteer does not mean your rear end is out of control or exceeds maximum grip, it means your rear end is turning at a faster rate of speed than the front.

It's proven fact that a non-staggered setup will be more biased towards oversteer than a staggered setup. You can try napkin math and theorizing all you want, but it's well known and proven that this is the case.

Cornering in general is all about the balance of the car. The tires DO slide even if they're "gripping." That's what lateral acceleration is. 50/50 weight distribution + non-staggered tires means the car WILL be flighty in a FR layout. This is the case because you are changing the overall balance of the vehicle. This is the exact same reason that many FF track cars run bigger tires in the FRONT than rear.

One can even experience different results @ different overall speeds. I find a non-staggered setup to be more stable @ lower speeds (read: Autocross) but many, (not all) will run staggered setups on their track cars. (Some still do run non-staggered setups on their track cars)

Do some searching, there are several people on these boards that have switched from staggered to non-staggered and back again. The real reason Honda built these cars with staggered setups was to make them less tail happy from the factory. Hell even AP1's can still be ass-happy.
