Well, for the helical, no modifier, but not OEM fluid...
Via mFactory...
Oil: Regular 75w90 Synthetic Oil for Street/Spirited use. Heavier 75w140 for Race Applications. Recommended brands include Torco SGO and Redline NS. Limited-slip Friction Modifier must NOT be used, as Torsen (read as helical) style LSD's rely on friction in order to function.
I can say that OEM is no where near the weights they recommend. OEM MTF is closer to a 5w-30, thus the emergency use recommendation...but drain and replace ASAP, for stock applications.
Nice brakes! I'd order a seal kit and rebuild them before install also. Better to go in fresh. I bought that kit with misinformation and sold it to a buddy as it wasn't for the Si/EX brake system, but the lower. And I didn't want to deal with downgrading. Luckily, a buddy had a CRX that it fit, so he grabbed it from me
Great combo on the suspension! Are you going to have the shocks revalved for the spring change?
