Salut,

pour mieu comprendre l'interet de cette pignonerie un "petit" extrait d'un article de chez minispares.
"To all intents and purposes then, the pre A+ 4-syncro ratios as used in all Minis from 1968 to 1980-ish is a better bet for a Mini. First gear allows a little more distance to be covered before second is selected, and drops the engine rpm less, so pulls a little better. Even better than this though is the 4-syncro S/1275GT ratio set as it also reduces the drop between third and top gears. The only down side is acceleration from standstill is slightly reduced due to the even higher first gear where the FD is unaltered. However - this is desirable where modified/bigger/more powerful engines are concerned as it improves initial grip (reducing wheel spin) and allows first gear to be hung on to even further. The closer ratios giving smaller engine rpm drops makes keeping the engine in its useful power band when driving ‘progressively’ much easier. So for a road going modified Mini - particularly when used in weekend competitions - the S/GT set is the one to have.
There is a problem though - availability. The S/GT gear set was relatively scarce in comparison to the standard set, consequently hard to find. Identification can only be made by having the gearbox off the engine. The first, second and third gears are identical to the standard Mini gearbox. However, the laygear is usually stamped 22G1040, but can be confirmed by counting the first motion gear (top gear/4th gear). This is the smallest gear on the clutch end of the mainshaft. It has 18 teeth compared to the 17 teeth of the standard one. As a bonus - and typical Leyland/Rover inconsistency - there were a very few A+ versions made that were fitted to a number of the last 1275GTs that had A+ engines. I’ve even had an MG Metro fitted with one!! "
