Schumacher have released a number of new parts for their Mi4 touring car. First up is are these medium flex 4 degree front caster blocks. Made with the Schumacher medium flex polymer that resists impact breakage but still maintains shape for driving and tuning precision, these new blocks will increase impact durability through the entire front suspension of your Mi3, Mi3.5 or Mi4. Also new are these improved arms which come in hard carbon or medium flex material, and are rapidly becoming a must-have. Beefed up for greatly improved durability, and slightly shorter for a dramatic cornering performance improvement for your car. The final part, the wide shock tower is a standard part on the Mi4, but fits the Mi3 and Mi3.5 cars as a direct replacement. Added body mounting stability and improved rear body downforce effect makes it a powerful and functional hop-up for your Mi3 or Mi3.5.
