MAD Wurks SP1 -4mm Rear Steering Arm (2)

After testing various rear toe link angles, we found that a rear steering arm 4mm shorter than stock stabilized the rear, added additional rear grip, and also allowed the car to carve corners better.  

Tuning Tips:

Make sure you put your car back on the setup station and adjust for the correct rear toe. We've found that 2.5 to 3 deg of rear toe to be optimal in most conditions.  We typically prefer in most classes 2.5 degrees static with .5 deg of toe gain for a total of 3 deg of max rear toe. 

Mod you may want to increase the static and potentially dynamic toe gain if on lower grip.

On the inner rear toe link, we start with a 1mm shim.  Running more shims produced inconsistent results and did not provide the same stability as running a shorter rear steering arm.

Includes:

• 2 - 4mm short rear steering arms.

Features:

• 3mm thick
• 4mm shorter than the stock sp1 part
• Reduced toe link angle to maximize rear stability and grip
