Default FRONT: T1R. REAR: POTENZA 070. STI. possible?

Hi.
I want to know what is the reason for the Subaru compay to announce that all the 4 wheels MUST be replaced to a same model of the tyre.
I'm planning to install two semi-slicks tyres (TOYO T1R) on the front axle and two Bridgstone RE070 tyres on the rear, in order to make the car less understeer and more over-steer tuning. The gear/Drivetrain is NOT DCCD.

The problem is that this is different model of tyres. the size of them is same. the grip isn't. Is that a problem to the drivetrain, gear or differencials of the car?


TY.

Back to front, RE-070 is more slick than the T1-R

If you want to dial out the understeer, you will need to spend money on the suspension. ALK and all that.
Also is your allignment correct? Get it 4 wheel laser alligned first.
Sticking the suggested tyre setup on will only provide oversteer in the wet (especially near zero degrees).

Any car can understeer. I can't say my Impreza suffers, I adapted my driving accordingly.

Different tyres front and rear will make the car unpredictable.
