XRAY - Model racing cars

Hi I run a 011T3 in the stock class in Australia. Where I race there is no boost/turbo function allowed. If you want you can add timing to the motor to your own liking.

I have been running a Hobbywing Justock with Speed Passion 17.5t motor +10deg or Thunder Power 17.5t with +38 deg timing [63mm tyres] approx 55mmpr rollout. I am wondering if I would be better off running a different ESC to get faster lap times. My driving lines are getting better and my setup I think is good but that is another story.

I have used a 60A Hobbywing XERun [with zero timing] esc and compared to the Hobbywing Justock I dont feel there is any difference. Comparing the justock to a Speed Passion Citrix I think the Justock is better..but maybe I am wrong? What do you think?

I have been looking at buying a Speed Passion V2.0 PRO. Do you think this would be a better esc to use than the Justock? Should I look at rather the Speed Passion GT2.1 Pro Stock Brushless ESC? or even the Speed Passion GT2.1 "EX" Brushless ESC? I don't know. Or am I just wasting money buying a more expensive ESC?

Zero-Boost should be Zero-Boost. I don't expect big differences between the spedos.
