The rear blocks all work and the difference in practice is . . . . . . .

Hey, I thought you weren't listening. :D
Anyway, please introduce me to your Greek. :lol:

I am.....

The lower the lower arms are in the chassis, the more roll you "should" have. I will ahve to take this to the Mugen forum and ask Robbie Collins for more insight.

Most grip roll eminates from the front end of the car having too much grip. A car can only have a certain amount of grip which is spread between the front and rear of the car. By adding grip to the rear wheels you reduce the amount of grip available to the front wheels without altering anything on the front end. By lowering the rear roll center using the A blocks you reduce the front end grip level which takes away the tendancy for the car to grip roll.

Ah... So it's more like using the A block to eliminate traction rolling than using it because it's good for the rear traction of the car on a high bite track...

Lower RC the chasis roll more but harder to, higher RC the chasis roll less but easier, the chasis quicker react to the ground make the car have more traction.

from my personal experience, the red shoe has the most grip and won't slip. you kinda don't want to use it though when the track is slippery... or still could but you have to tighten the clutch.

So one could say that the Black shoe has the least grip and Red shoe the most, beeing Gray in between ??

For some reason i hate the red shoes, ive always had problems with them slipping or wearing to fast, the grey shoe seems to grip and wear the best for me.

i am not 100% sure if this website has it, but they sure do have a wide selection of screws. this is where i get my aluminum screws for the less stress parts of the car to shave off weight.
