Pretty much any 'mini' servo. The chassis is slotted to allow for the different output horn location of the servo.

The Spektrum H5020G is probably the best pan car/mini servo currently available. It's digital, metal gear, plenty of torque and twice as fast as any of the other common servos. Its designed as a Heli tail servo which is a much tougher and precise application than r/c cars.

Length: 1.37 in (34.7mm)

The real kicker is that it sells for $49.

I have been running them in my 12R5.2 and 10R5.1 for almost a year now and they have been perfect.

I know LRP does not support this, but it works
I tried this and yes the esc works fine but i constantly had issues with my laps being missed,and i was the only one .
I fitted a booster battery and the issue was gone.

I used this:

It works with the horn that comes in the kit.

Tire size will make the most difference

Smaller tires, with very round edges 42Rr, 40Fr, Half sauce front, full rear, apply grip additive no more than 10m on front tires, from application to run
One run per day, per set of tires
Softer roll setup, 10k side dampers, could test by removing 1 side damper to see if less damping feels better
Side springs, Silver just touching, or Black 2 turns down
Pod should be level with chassis, with full weight of car on surface, no droop front

What brand wheels are you running ?

+1

I saw his post on the ask Keven thread and said the same things. Keven's 2013 Snowbirds and IIC setups are good for crazy grip too.

Default Savox servo

Did anyone try a Savox 1250-MG yet in their 5.2 or any 1/12
How is it compared to Futaba 9650 ?

Try Pink/Pink instead of Mag/Mag.... and go about 2mm smaller front and rear, like Dave said. Heavily radius the sidewalls, etc.
