I have an 09 c2s
I have 295's in rear ps2's
Buying pss's and wanna run 305's

The car has front end push/under steer I've experienced it several times
Luv the car I'm not complaining its controllable and predictable

I don't want to aggregate the tendency to push front tires
How will it effect handling if I go 305's
What can be done to counter, wider fronts too?

Suggestions, experiences, comments, plz

Thanks

 

Lots of folks run 245 fronts to go with 305 rear.

 

I ran a 245/305 combination on my 09 without issue. Handled find on track and street.

 

I don't think that changing the rear tire to 305 from 295 will make a different. I did exactly the same on my c2s after ps2 (295) were done got pss 305 and 245 front. All c4 cars have 305 originally. I think doing alignment will have impact on the way how the car handles and will recommend doing that .
