Weld-in reinforcement caps the strut tower with a 3/16" plate and ties in the fender rail with an 1/8" brake bent plate. The precision laser cut reinforcements are perfect for those planning to install stiffer coilover suspension and strut tower bar. **Apron plates are packaged as bare metal and must be welded. Strut tower plates are coated in case you dont plan to weld them in.
