And I only found 75W90 for Royal purple
I drag race almost every week if in the winter, and I plan on taking it to the track when the weather cools off a little bit.

Conclusion of the reviews:
Red Line less performance than RP, better than OEM and most users say after they tried it, it shifts like butter but not the best for long term use or DD I might say.

How would RP harm the tranny in the long term?
Check out Amsoil transmission fluid, i ran it in my 350z and it made the tranny much smoother... The specs on it are fine to run, the owners manual should give 2 variable choices and Amsoil was the other choice for weight specs. Hope that helps.
Biggest thing is to make sure its GL4 for the tranny and gl5 for the differential...
