I know that the right driveshaft on a c20xe engine with a f20 gearbox is longer than the left. For that, the one wheel spins more easily under of pressure of accelaration. One mate with a gte 16v have changed the right driveshaft with one another from a newer vauxhall and it is split in the center to imitate with left one. And he said to me that this new driveshaft is for more evenness betwween the two wheels when they are spinning.
Do you know this type of driveshaft?
Could be from cars with f18 gearbox?
