Haha. I was reading up on those. Highly recommended for autocross or racing.Instead of my breather, i now have an Oil Catch Can for the differential oil. If you could sneak under my car now, the right side of the axle is absolutely coated with oil, that's what happen when you shake it in an autocross course lol
Next spring i'll get back in touch with my mechanic to schedule the installation of my 3.73 and Watts link, i am sure he'll tell me it was missing half of the oil that should have been in there in the first place lol Happy I finally put the oil catch can haha.
