I’ve heard discussions about switching to 75w 140 from 75w 85 gear oil for tracking, can anybody give me some input if it’s a good idea and or if I should use it in the rear differential? For some extra context I have a syvvecs AWD ECU and it doesn’t immediately go into limp mode under hard driving. Thanks!
I didn’t have any issue with the dynamics of the awd system from factory but I’ve been continuing to use my car as a guinea pig for upgrades that sound interesting. I preordered the JXB upgraded driveshaft on a whim out of curiosity and had it installed recently and I was not expecting a huge difference but I was genuinely shocked how wrong I was. After driving off the lot at the mechanic shop and doing the most mild pull I noticed a distinct push from the rear that you feel with RWD cars and much sharper acceleration. Mind you that when I felt this it was on the 50/50 track mode. I’ll be doing more testing this weekend in different drive modes but I’m curious to see if it noticeably reduces understeer in spirited driving. I’ll be adding updates as I learn more, but for the time being I’m very impressed by the added responsiveness and push in the rear wheels. (Pic for engagement)
