    QUESTIONS & ANSWERS

    • Q: Fitment   EliteiDutchHD11 months ago

      Will this fit on a RHD car?

        A:  HArd to say, you have a BUNCH of stuff over on the right hand side of the engine bay, so you would have to mount this on the left side, but at that point you would have to modify all of the lines, and possibly the brackets to get it to work. So to be safe, I would say no. But it could work if you don't mind hacking the kit up to make it work.
