Suspension
T-plate stiffness controls rear traction. Springs and sway bars tune the rest of the balance.
Why it matters
The T-plate is the primary tuning lever on RWD Mini-Z platforms. Carbon fiber replacements give you consistent flex behavior and open up a meaningful range of tuning options that plastic stock parts simply don't.
