How do I confirm compatibility with my MR-04?

Compare the listed compatible model codes with your car and inspect mounting bosses; if uncertain, trial-fit before final assembly.

Is MR04021 stronger than stock parts?

The 4140 steel and 7075 alloy combination is chosen for durability and stability, but actual strength versus stock depends on the original material and design used in the factory knuckle.

Do these require special tools to fit?

Standard RC tools are sufficient for installation; retain original bearings and screws or source matching hardware if yours were lost.
