What ride height should I use on carpet for Team Associated RC10 B84/D?

For the RC10 B84/D, start at 11 mm front and rear on medium-grip carpet. On high-grip carpet, 12 mm front and rear is a good starting point; those are the carpet ride heights used by other B84/D racers.

Set ride height with the car ready to run, on a flat surface, and measure from the chassis to the track. Lowering it can help keep the car settled and reduce traction rolling, but too low can make the chassis scrape or bottom out. If it bottoms, raise the ride height a millimeter and retest.

For your RC10 B84/D on high-grip carpet, start with a 1.8 mm front anti-roll bar and 2.0 mm rear bar. Those are the recorded high-grip carpet settings for this car; the 5.5T motor doesn’t change that starting point.

The bars control how much the suspension rolls in corners. If the car feels too edgy or traction-rolls, try one change at a time: reduce the rear bar to 1.8 mm, or stiffen the front bar. A stiffer front and lighter rear can help reduce traction roll, but may make the car push more.

For the RC10 B84/D on high-grip carpet, start with 4.0 lb red front springs and 2.6 lb purple rear springs, with 650 cSt front oil and 550 cSt rear oil. The setup data is categorized by track grip, not motor turn, so this is the high-grip carpet starting point for your 5.5T car.

The springs support the car’s weight and influence how much it rolls; the oil controls how quickly the shocks move. If it feels too stiff over bumps or loses grip, try slightly lighter oil. If it rolls too much or feels unsettled in corners, keep the spring rates and test a small oil increase. Change one thing at a time, and use the same oil brand or compare by cSt since “weight” labels can vary.

For the RC10 B84/D on high-grip carpet, start with 40,000 cSt front, 100,000 cSt rear, and 750,000 cSt in the center diff. These are high-grip carpet values for this car, and the setup data is not specific to motor turn, so they’re a reasonable baseline for your 5.5T.

The front and rear values are for the gear differentials; the center value applies if you’re running the center differential. Use the same viscosity standard when matching oils, since brands’ labels can differ. If you’re changing the setup, make one adjustment at a time and test how the car puts power down and turns in.

I can’t give a reliable pinion/spur combination for a 5.5T from the B84/D setup information: it lists 72, 75, 78, and 81T spurs, with 78T as the default, but doesn’t provide a pinion recommendation or a high-grip carpet gearing value.

The right pinion depends on your motor’s KV, battery voltage, ESC timing, and track layout. If you share those, I can narrow down a starting point. Until then, use your motor or ESC maker’s gearing guidance rather than guessing, and check motor temperature after a short run before continuing.
