Wave­trac F40/M32 dif­fer­en­tial

Performance Vauxhall - - GEAR -

Re­gal Au­tosport have just started sell­ing these Wave­trac ATB dif­fer­en­tials for the GM F40 gear­box. They dif­fer from reg­u­lar LSDs be­cause they’re de­signed to pro­vide trac­tion to both front wheels all of the time, even when one tyre has zero axle load. At near zero axle load, each side of the Wave­trac diff starts to turn at dif­fer­ent speeds, al­low­ing the pre­cisely en­gi­neered wave profiles on the side gear and its mat­ing preload hub to ro­tate rel­a­tive to each other. This causes each wave sur­face to climb the other, forc­ing them apart. This cre­ates enough in­ter­nal load with the diff to stop zero axle load con­di­tions. It’s im­pres­sive stuff and well worth look­ing into if you’ve got a high-power VXR. Re­gal Au­tosport are of­fer­ing a 10% dis­count on the M32 for a limited time, bring­ing the price down to £755, and an in­tro­duc­tory F40 of­fer of £788 for the F40, just quote ‘WELOVEWAVETRAC’ when or­der­ing. Price £840 for the M32 (£755 with dis­count), £985 for the F40 (£788 with dis­count) Con­tact www.re­gal-auto.co.uk
