Welcome to the Werkz.

Have a look at RealOEM.com BMW E12 530i Rear-axle-drive
It looks like the ratio is 3.45, but that might not be 100%.
Have a chat with Dan @ Diffsonline diffsonline.com - Custom Geared BMW LSD Differentials
the other option is track down some tyres with a larger rolling diameter, that will have a similar effect at a fraction of the cost.
