What shock oil does the WIRC SBX-1 come with?

Out of the box the SBX-1 runs 600 cst front, 600 cst rear (P-ONE oil), on 8 x 1.3mm front, 8 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.

What springs does the WIRC SBX-1 come with?

The kit springs are Kit (#100125) front, Kit (#100126) rear. Stiffer springs suit high grip and big jumps; softer springs add grip on slick or bumpy tracks.

What diff fluid does the WIRC SBX-1 come with?

The kit diff fluid is 5,000 cst front, 5,000 cst center, 5,000 cst rear. Thicker front adds steering on power; thicker center sends more drive rearward; thicker rear stabilizes the car under throttle.
