Rebuild a grinding 5-speed with new synchros Limited

A grinding Evo VIII/IX 5-speed usually needs synchro rings. One rebuilder uses bronze rings instead of the factory brass ones (triple-cone 1st-2nd, double-cone 3rd, single-cone 4th-5th).

Caveats: Single vendor source. The 6-speed MR gearbox is a different unit.
