Your concern is well founded....rest assure in my opinion a half-ass product is worthless product...if even after intense research and testing the product just doesn't work....it WILL NOT be produced...One of my reasons for doing this (and many of you may disagree, although I hope you won't) is because I believe the Z32 is a great platform for a supercar...and I want a Z for myself that is a supercar...and I want to offer exceptional parts for others who may feel the same way or may have other uses for such parts...
