I have an 04 ZR Enthusiast model, its an automatic but I have searched all over the internet including the top 100 questions and can not find the answer regarding a Roadster. So my questions are:

Does anyone know if the 04 Roadster Enthusiast automatic comes with a LSD? Also has anyone with a ZR, installed a Quaife QDF10L??

Thanks!

 

Automatic Enthusiast models did come with LSDs from the factory

 

Thanks, worth it to upgrade with an aftermarket one then?

 

The stock LSD in a Z33 enthusiast model is a viscous unit (VLSD). It's a low cost, low maintenance option that works fine for street use and the occasional trip to the track. If you must have an aftermarket LSD, be sure it is compatible with your VLSD case and axles.
