Should I use an oil modifier additive in Eaton diff for road racing?
Car is 3rd gen used exclusively for 15 to 20 minute road races on Toyo 888 medium compound trackday tyres not slicks, should I use an additive or not? Its a new Eaton Posi plate diff.

From the website.
Eaton Posi
What kind of oil should I use? Can I use synthetics? Do I need a friction additive/modifier?
Eaton Posi units perform best when using GL4 (or better) mineral/petroleum based gear oil. A four ounce bottle of friction additive/modifier is also necessary for optimum performance.

Yes I saw that but was wondering as this is a purely competition car and I am not worried about pops and bangs from the diff as you would on a road car would I have got better bite without the additive. I will use it anyhow.
