The picture look like Yokomo springs to me - Yokomo springs have less coils than the AE/Losi ones
Losi springs only put a small amount of paint on the top of the spring, AE big bores come with heat shrink of the appropriate colour for you to put on yourself.

Personally i prefer the feel of the yoke springs over the AE ones as the progression of the spring is different between each brand.
Front i have Yellow, Blue and Red and Rear i have yellow, green and blue - softest through to hardest. Normally run the red spring wet and dry in mid and rear and the kit blue in the dry and yellow if its wet mid or rear.
I also played around with the pistons again the weekend and found a better setup where i could just throw the car into the corners without grip rolling - a few of my friends tried it after the meeting and said the same
