Please, upload screenshots with 0-100 race result on dry asphalt (MIDLANDS 5-1), upgrade status and 0-60 acceleration value of tested car. Fill the form with upgrade stages of your car, 0-60 acceleration from your car card, and and 0-100 from race result. After success moderation, you can see MRA value in car lists. If you can't find upgraded car in list, please upload yours. Thanks!
MRA counting via formula: 100 * (acc0_60 / (acc0_100 - acc0_60)). If there are many MRA data for one car (for different upgrade stages) then shows average value.
