“This just looks incredible when you pull it out the box, and being able to drop the revs for long haul runs is something that shouldn't be seen as a bad thing. I know it will make the gears less engaging by how long they run but it's a trade off for a more comfortable ride on the motorway.”

“Seems really good quality, well see if I break it lol. Tooth count is 13 on the pinion and 43 on the crown wheel. So for anyone who was confused if the ratio was 3.33 or 3.3, it's actually 3.3076923077.”

“Definitely needs to be paired with a 6 speed or a bmw trans and pushing decent power to get the most out of the gear-set but it is a beautiful and well made piece that arrived in great packaging.”
