Why did you go with 75w90 and not the factory 75w140?

Good catch Jason. I missed that. Yeah that conventional oil is going to cook and break down fast in that IRS pumpkin. That is why Ford recommends the synthetic. You don't have the volume of a SRA. The oil in the IRS gets much hotter than the oil in the SRA mainly due to the capacity difference. Clutches in the Traclok won't last long.

You are going to love the way the IRS is going to feel now with ftbr bushings. I did this mod few years ago. The difference is night and day. Best mod that can be done to a IRS.

Well finally got to go for a drive. Absolutely amazing. Completey different car. Between the new poly motor mounts and FTB kit there is no drivetrain clunks. Car handles great, so predictable now. Couldn't ask for a better kit.
