Hi Stuart,

Great question! The answer is, there really isn’t any benefit other than if you want to run the stock disc backing plates. These plates are not all that necessary and will not bolt on with a stock drum spindle. On the flip side, by using the stock drum spindles, you don’t have to align the car when you are done and you don’t take a chance on damaging the ball joint and tie rod boots, this happens sometimes when removing the old spindles.  When I developed this “No Hassle” kit, it was done with the premise of helping the people at home with an easy way to convert to disc with out a bunch of special tools.

Lastly, You have the wrong kit number for a No Hassle kit for a standard Bug. The kit number is 498492. The part number in your question, 498496 is for a Super Beetle! Please don’t forget the bearing kit, part# 498490L

Thanks for allowing me this opportunity to help,

Andy
