Found this interesting.. copied on here for you guys.. hope you guys have a good xmas tomorrow
Rake & Reverse Rake
This is simply the gap & how level the car sits relative to front & back. Rake can only be "measured" by eye, as far as I'm aware, and can only be truly represented when the car is stationary
Zero (no rake) = sitting level
Rake (positive rake) = front lower than rear
Reverse Rake = rear lower than front
Rake (positive rake)
Most cars from factory come like this, especially true in FWD cars. It gives good front-end grip and less chance to lift a front wheel under cornering & acceleration, rear wheel lift under hard cornering to be expected. Negative effect is the rear can get "light" and twitchy under heavy braking
Reverse Rake
Found in some drift cars, this is something to be desired if going for good rear grip. Front turn-in is compromised, but transitions & fast entries become more stable and give ability to drive harder on the throttle on the exit of a drift.
Squat & Anti-Squat
Squat & Anti-Squat are the percentage differences between the front & rear height under braking and acceleration, as weight transfers. For this argument, I will only talk about a car under acceleration. Squat & Anti-squat can be adjusted by damper rates, spring rates, ARB's & roll-center adjustments.
Squat = Rear of car will lean back, accepting the weight transfer and putting more weight over rear wheels
Anti-squat = Rear of car will not lean back as much, less weight will be transferred during acceleration
Squat
Gaining more squat gives the car better traction & grip under acceleration due to more weight being pushed over the back wheels. This gives better rear grip, but front wheels have less traction as weight is removed off them, giving less steering ability on-power.
Anti-Squat
Increasing anti-squat gives the front wheels more chance of traction under acceleration and better on-power steering under hard cornering. The disadvantage is the car will have an increased chance of becoming unstable in the rear, especially in fast & hard cornering due to less weight being transferred to the rear.

Rake adjustments & squat adjustments come hand-in-hand when it comes to fine-tuning a car's suspension setup.
