Here's a short summary of mods with a speed secondary bonus.
Taken from the Mods Manager database, we filtered all mods with a +speed secondary bonus.
We grouped the data around the speed bonus to identify the rarity of a speed bonus.
We've got millions of mods in the database more than 1,5 millions have a speed secondary bonus... But less than one thousand are giving a speed bonus above 20.
Are you among those lucky players ? My best one is +17 at the time of writing, not too bad...
