Default Empi Rear Disk Conversion long - short axle

Hello,

As part of my rear end rebuild which includes a new engine, gearbox and axles. I am converting my 1970 Beetle from Long to short Axles so i have some more rubber options.

Im currently running a Empi Rear disk conversion thats been on there for 8 or so years. Looking on all the parts websites they sell the conversions listed as 68 onwards and then a seperate kit for pre 67 cars.

Does anyone know what is the actual difference is between the kits, Want to try use as much of the existing as i can but cant work out why they list two types. Only thing i can think of is the caliper mount

The difference is the wheel PCD (Pitch circle diameter) pre 67 cars were 5x205 where as post 67 are 4x130

The length of the spline will be longer on your current brakes and will require machining to fit the shorter axles, have you concidered using your existing axles and getting wheels with the correct offset, I have an early and a late car and did that. As cox71slammed said, the PCD will be different also.

Hi thanks for the replys

Sorry i wasnt clear enough in the original post

Both empi kits 68- onwards and upto 67 are both the same stud pattern 4x130 theres just a 50 difference in price, but as i have a kit fitted wanted to use it if possible

Im all sorted now, it looks like the only difference is the use of a Spacer on the later kits, so i can just bin my current spacer and it will fit the shorter axles as is.
