Restrictor plate question

If I upgrade the restrictor plate on my Ford GTLM/GTE racecar, the engine hits the rev limiter on the Mulsane straight & my MPH drops from 182 to 177. Is there anything I can do to stop this from happening?

Lower your final gear ratio a bit

It’s at 1.24…maybe 1.15 or would that be too much?

Never mind. Looks like 1.22 is going to do the trick. Thanks for the tip.
