Personally I think the differences arent as noticeable with different brakes. Maybe its a little easier, I havent had many problems. Its all about the tires. When I eventually started dinking around with my toyota pickup I went from stock wheels and 50$ tires to Y-rated low profile street traction tires. I could take corners going way faster then I ever would have dreamed of and the lowered suspension and tire combo made it possible. They only came with about 30K mile rating but those things could come to a dead stop in the pouring down ran in no time flat, even if they locked up.
When I got tires for the 53 I spent more then I had planned and went with a nice set of Toyo street tires, even though that truck wont go fast enough to be an issue. Better tires have softer rubber and grip awesome! The downside is they dont last very long.
When I got those tires on my toyota I had a biker friend tell me about how he hated riding behind someone in the rain. He said it was like having a hose sprayed directly on you due to how well they moved water through the tread and out the back.
Look at your car, brakes can help but ultimately your relying on that rubber in contact with the ground to stop you. By no means am I putting down brake systems in lieu of tires, you still need a functioning brake system and thats not the place to save a buck.
