Default front arb upgrade

Hi I have a type-r 99/00 and if I drive on the track and come out of the corner the car will brake out on the back it's not scary but I like to counter this.
If I set the dccd setting 2 or 3 kliks, so it goes more to 4 wheel drive it's better to run the car out of the corner less sliding.
Now I like to no if I put on a bigger arb on the front of the car will it slide less and how big a arb do I need, standard it's 20mm if i put on a 27mm will this be to big or will this give a hole other affect on the car.

I'm no track expert, but I'll have a go, as no one else has:

What size front and rear bars have you got?
What tyres?
What static camber settings have you got - front and rear?
What spring rates, dampers and bump stops are your running?

During corner turn-in, when the front MacPherson strut camber curve starts to collapse (losing negative camber), the tyre rolls onto its outer edge/wall causing understeer.
In these circumstances, with a MacPherson strut front suspension, a bigger front bar will maintain the contact patch, for longer.
So, if you're experiencing turn-in understeer, a bigger front bar, at the same corner speed, will probably give you more front grip. It will eventually understeer, but it will be at higher corner speed.
