Front strut brace for BMW Z4 Roadster/Coupe (E85/E86) 2003-10 excluding Z4 M with S54 engine. Each Racing Dynamics strut brace was design by professional race car engineers for chassis stiffness and ease of mounting. Features:
- Each strut brace is designed using our specially designed extrusion for increased stiffness and properties to allow bending of the alloy without crimping at the bends or need to cut and weld multiple pieces (an inherently weaker design).
- Each movable joint is approximately a 2" bolt and bushing which is extreme rigid in torsion and compression which are the 2 major stresses we are trying to increase in high performance handling events. Much stiffer than any heim join design.
- End plates are machined on high speed machining centers for exactness and repeatability ensuring the BMW owner of the finest strut brace available anywhere.
