With this the rear was more planted and I felt more confident with the car. With this set up I could get a quicker single lap time, but the car was still inconsistent, a problem I found using the ARS.

I have changed back to the standard rear set up (non ARS) and found I have a lot more confidence in the car and lap times are more consistent and therefore the overall race run is quicker, even if the single best lap is fractionally slower
Did you add shims at the wheel to allow for the fact that the ARS reduces the track width by quite a lot, seem to recall it's 1mm each side!

Many guys use a 96T spur, but depends on each persons preferences. Several 17.5 motors work well geared between 3.6-4.0 Final Drive Ratio (FDR) range. If your larger track has an open layout, I'd recommend starting at around 3.6'ish FDR. A 45T through 50T pinions would cover the gearing range for fine tuning to suit different track layouts/needs. Hope this is helpful and have fun at the track!

See what the guys are running locally as far as their FDR goes and if they are running a fan or not. My guess would be anywhere from a 3.2-3.6 FDR. I usually like to run a 92t 64p gear for 17.5, and occasionally a 96t spur gear. Anything larger is rarely used in stock, and smaller gears tend to have troubles with the motors contacting the top deck. As for pinions I would get a range of about 48t-55t. That way you can be prepared to run whatever FDR the local guys use, and then adjust slightly for your specific motor.

A fellow racer used the Avid '14 Graphite Chassis last weekend with exceptional results (also used Avid shock towers and thin upper deck). Working to modify an Avid graphite chassis to fit a '15. Have had very positive results using the Avid shock towers and thin upper deck on stock Xray chassis.

First race day at indoors running 21.5 blinky class on carpet and I won by 2 laps.
I still have minor changes to make.
What a great car.

Recommend Mid-6000 mAh's or higher (hardcase battery/ROAR approved) with a high 'C' rating for stock applications. Most all of the manufactured labeled batteries perform very well. Example, but not limited to: Team Powers Racing, Murfdogg, Orion, Trinity Revtech, ProTek, SMC, Psycho Cell Racing, Intellect, Reedy, etc...

If you buy Revtech, check that it has roughly the capacity stated on the pack, I had problems with their 1s packs.
