On the E8T Evo3's stock 50T spur that is about 15T for 1800–2300 kV. Tight tracks gear down, open tracks gear up. For a starting pinion matched to your motor, use the So Dialed Pinion Recommender with the E8T Evo3 selected.
The E8T Evo3 has an internal ratio of 4.3:1. Final drive ratio = spur ÷ pinion × 4.3. With the stock 50T spur, a 12T pinion gives an FDR of 17.92 and a 18T gives 11.94.

Out of the box the E8T Evo3 runs 35 wt front, 27.5 wt rear, on 6 x 1.3mm front, 6 x 1.3mm rear pistons. That is the kit setup; you will need to adjust it for your track conditions. The RC Setup App can help dial it in.
The kit springs are Gold 79.6gF (#109810) front, Orange 82.1gF (#113476) rear. Stiffer springs suit high grip and big jumps; softer springs add grip on slick or bumpy tracks.
The kit diff fluid is 7,000 cst front, 7,000 cst center, 4,000 cst rear. Thicker front adds steering on power; thicker center sends more drive rearward; thicker rear stabilizes the car under throttle.
