Is this an effective technique for FWD cars? I had a LOT of understeer at the last Sunriders event. I feel this is due to:

1. My horrible stock Bridgestone Potenza RE92's.
2. No rear anti-sway.
3. Stock suspension which allows a good bit of body roll.
4. Me still learning how to drive fast properly.
I found myself often times in corners, coming out, having to get off the gas and work on unwinding the wheel slowly in order to overcome understeer.

Does trailbraking help to produce quicker lap times through getting rid of understeer, or would it make my slower through slower corner entry speed?
