I am considering going the same route - TA's mounted on light racing rims to keep weight down. I find the Contis heavy, unresponsive and definitely unstable over 125 mph.300cMexico said:Hello. Here is an update. I have pushed the car to 250 Kmh which is about 156 MPH.
I think that is the limit of the engine/trans not so much electronic limiter.
As for the ride i changed tires and put the 245/55 18 bf goodrich and it made a night and day difference. car is a lot more steady.
These tires are great.
