    Wow!!! I have to start off by saying this kit was effortless and very well put together. We were very impressed by how thought out and straight forward everything was. The DIY is comprehensive and is exactly what you need to get the job done. With regards to fitment I had calculated using my new CCW race classic wheels.

    NOTE: Unfortunately the BBK will not clear the OEM 19″ ZCP wheels without a significant spacer. I would say atleast 18mm but more than likely a 20mm in the front to clear it comfortably. With my CCWs we threw on a 5mm and it fit like a dream (per my wheel specs). I am very happy with the kit and look forward to testing out it’s capabilities on and off the track!

    Finally, it goes without saying that The Buildjournal team (Andrew and Connie) always go above and beyond with providing amazing service addressing any questions or concerns you may have. Definitely make you feel like family!
