Up until now we have been offering the VT2-500 for the Z4M in an unofficial fashon as it has not been an official production kit. We have made a few kits for those looking for more power over the VT1 kit. We have a new project Z4M that we will be devolping a true production VT2 kit on over the next 30-60 days. This kit will be a more refined version of the current beta VT2-500 kit. I will have more details on this kit very soon.
If you guys have questions on the product you can always email or PM me direct.
Now you tell me? after i have bought the VT2-500? :P kidding.
Good luck guys, i hope you will bring our platform up from VT1-445 to low compression high boost reliable applications. I think most people here agree that the Z4M is a wonderful car to work on and it deserves the attention.
