Re-curved Distributors, Ignition Components, A series Mini Cooper Sprite

For maximum performance from your British Sports car engine the timing of the spark must be accurate, and when compression ratio and camshaft in particular are changed, a re-curved distributor is essential.

APT favors a brand new Lucas unit. These are re-curved for us by Aldon Automotive, who probably supply 75% of the re-curved distributors for British cars worldwide.

Maximum compression ratio for any road car running today's pump gas should be at the most 9.6:1 (unless the car is always at above 3000 feet elevation).
For road cars with less than 10.0:1 compression ratio you should use a vacuum type distributor, to make sure there is enough advance at idle and cruise.
Use manifold vacuum if possible, only switch (in most cases) to "ported" vacuum if the engine rattles for a couple of seconds when you go quickly from cruise to full throttle.

If your compression ratio is above 9.6:1 you may be best to go with the non-vacuum road performance type distributor. Aldons refer to these as "yellow" and race as "red".
