Is always a domino effect, one after another that is why modding never ends.....power without grip would be useless.
With upped power need better brakes to stop.
If good brakes with lousy tyres, then it is useless.
imagine huge hp, coupled with good bite on the brakes....but poor tyre grip on the road.
So, eventually, one need to upgrade to better tyres if they had upped the HP of the car.
