Wait what? Is that 2 full degrees of toe you're recommending? Thats way too high
First, you need to understand what the different settings actually do:
Suspension adjustments and how they affect handling
Cars out of the factory will generally have minimal toe and camber because most people spend most of their driving going in a straight line, bumming to and from work or the grocery store or whatever
A track car wants to maximize grip across a variety of circumstances, including turns, during which the tire doesn't want to be straight up and down. Race cars want some level of negative camber. How much depends on a bunch of other settings, such as the tire, the suspension, and the surface
Read the actual track guys talk about it here:
Track Alignment
and here
Mixed use alignment? (Attn:Hotrodz, Rusty)
-3 camber front and -2 camber rear is pretty common, and most people want as much caster as possible up front for dynamic camber gain during compression
toe also is generally minimal. A bit of toe may provide high speed stability
