S52 w/ ZF gearing video

[JMPAuto]

I've been switching diff on my car depending on the track. I've ran 3.25, 3.46 and 3.73. In this video, I'm running ZF tranny with 3.73 on 255/40R17 rears and 235/40r17 fronts.

Track is Streets of Willow running CW. Using only 3rd and 4th gear most of the time. This might be helpful for some people still deciding what gear ratio to run on their swap.

I don't drive my car on the street anymore. Base on calculation at 65 mph, should be around 3000 rpm on 5th gear.

Perfect gearing for BW. Pretty close to redline at 5th before the last turn doing cw.
