Question 16" front, 17" back, non Subie handling Q

Ok guys I am posting it here cuz it is a car Q but not for Subies.

Check out this situation:

RWD
Indipendant Suspension on all 4
Rotors on all 4
Fat Sway Bars and both strut tower braces
Springs and shocks/struts done (Eibachi(?)/KYB)

Now to waht I am actually wondering about:

Rear tires 265/40/17 on 17x8" rim
Front tires 225/50/16 on 16x7" rim

Obviously, fronts have taller sidewalls and surely softer one too, given that all4 tires are same brand (Yokohama A520).

Ok, so how will this set up affect car's handling and if there are negative effects of it how can they be offset?

Thanks guys!!!!

Eugene

PS: Why it is the way it is?

1. Looks AWESSOME
2. It was thought that is might improve cornering with front flexing a bit and giving greater lean in.

Shouldn't the car lean to the outside instead of inside according to the law of physics? That should be the same effect as a soft suspension which sucks at cornering.

Ok, thats gonna be a hand full to handle.

Thats a common drifter tire set up, putting on softer, higher sidewall tires on the front.
Of course they usually put less rebound on their front shocks, and set the camber so about 3 degrees, and about 2 degrees of toe in, but the tires do alot of it.

As you brake the car the weight is going to shift to the front, the front tires will compress, the rear tires will loose traction. A *little* throttle in a situation like that, and your gonna have yourself a nice tank slapper. If you want better handling, go for a tire with a smaller sidewall. The less squat you can get on the front end of the car, the tighter it will handle. Just make sure the suspension is set up properly so you dont get understeer.

As long as you arent driving hard, i dont see a problem with the tire setup. But for going through the twisties, i wouldent recemend it, unless you are VERY confident that you can maintain a drift, and recover, becuase that is what will happen.
