I played the pro am modified series and stuck at blue city reverse

I want you all to beware that the pro am modified series at blue city reverse in this game is impossible, it gives you 45 seconds to beat the track in that required time, i was close with a time of 45:529 in the 22b impreza (name is lunaloud). If you can help just give me a grip tune for the 22b impreza in b class
