On my RX8, I switched out to Redline MT90 for the 6MT transmission and Redline 75W90 NS for the LSD and it really seemed to make shifting much smoother. I would be interested to hear what others have done or are thinking. Here is a link to Redline http://www.redlineoil.com/products_g...7&categoryID=7

yes i have switched them out. while i did notice a tad bit more smoothness its not that big of a difference. the only reason i upgrade my fluids is for the fact i do track days. and i want the best in my car at that point.
