Это шедевр

Не знаю чуваки, чего вы ждете от этого приложения. Я считаю это просто шедевр. Я кучу колес уже прогнал через это приложение. Реально наглядно понятно что да как поменяется относительно сток колес. Или текущий колес. Резину найти подобрать, вылеты. Господи. Никита который это разработал. Чел, просто спасибо тебе большое. Ты очень меня выручил много раз уже!
