This front subframe chassis brace is MUST HAVE for anyone who is serious about getting their G37 to handle & really grip the road with authority!!! I have a G37 IPL and I have installed all the rear chassis braces I could find, strut tower brace, Hotchkis sway bars front & rear w/ Z1 end links and Michelin 245 35/ 20inch tires all the way around.....all these upgrades made a definite improvement, but this front subframe chassis brace truly tied everything together!!! Simple install, it me took approx. 10-15 min to install with simple garage tools (wrench/ torque wrench/ sockets, floor jack, jack stands and impact gun (optional). The fit & finish is truly magnificent and it makes my G37 IPL feel extremely solid/ connected to road. G37s are a heavy car and you can definitely feel all that weight when you head into turns and corners at speed, after installing this brace you can navigate winding turns at speed with complete confidence, complete control and complete ease.
