I've got vol 37,69 and 89 for the R34...very informative. List aftermarket parts of all kinds...In particular I love the wheels sections, has pics and correct offsets and widths suited to your particular make and model.
Useful to identify bodykit parts, suspension, wheels, turbos, exhausts right down to accessories like gearknobs, pedals turbo timers...u name it they've pretty much got it.
