Yokomo SD-202L15 1.5mm Steering Rack for MR-4TC SD LCG  [SD-202L15]

Compact steering upgrade for MR-4TC SD LCG

This steering rack is intended for use on the MR-4TC SD LCG chassis and allows you to modify steering geometry with minimal disassembly. The part shifts Ackermann by moving the steering rod 1.5mm forward or backward from the stock position, giving a reliable mechanical change to steering response and turn-in characteristics for drift or track setups.

Fitment is simple: swap out the original rack, install this unit, and place the steering rod into the alternative mounting hole to change the linkage geometry. Because the adjustment is achieved via a lateral rod offset, it alters front wheel steering angles directly and usually does not mandate radio or servo reprogramming.

Practical advice: small, repeatable tests work best. Change positions one at a time and note handling differences. Use this mechanical tweak alongside tyre selection, toe settings, and damper tuning to dial in corner entry and mid-corner balance.
