Also consider weight transfer when braking for corners, if you apply just the right amount of braking then you transfer the weight onto the front wheels which will push the tires into the ground more. Then when you release the brakes the car will be more neutral allowing you to feather the throttle to control the balance of the car into the apex, then when you can see the exit of the corner in the distance you can start to apply more throttle and come out of the corner faster. If you go in too fast and try to brake hard then you will upset the delicate balance and probably understeer as the front tires scrub across the tarmac instead of biting. Anyway, all this is more usefull on a track rather on our badly built public roads with the uneven surfaces, pot-holes, grime. Plus, you car needs to be setup well with all the suspension components and tires/tracking in good condition. until these have all been checked out and you have learnt the delicate balance of your car a bit more then i would suggest scrubbing off a bit more speed before cornering otherwise its brownsville time!
