Hello i am brand new to the forum and was hoping for some help..I am coming off lease on my 2008 G37 Coupe and will be getting a 2011 M37x..I saw the aero kit and i love it..infinit said they could add it to my lease but would require me to put quite a bit more to keep my payment reasonable..My question is does anyone know the difficulty of installing the kit? I have quite afew friends who are mechanics and body men, Is the kit a very difficult install that i would be safer having Infiniti handle? Or is it more simple that i could order the kit from them and do a self install...Thank you in advance for any help and imput...
