You definitely need an alignment or something man, I was in a stock SR w/ sidemount, stock brakes and mismatched street tires when Varun was driving (fobwall’s car w/ advan 3 spokes) and he dialed you two guys in the skylines in pretty easily 
you’ve got all of the goodies on the car to have a beat so i imagine after some suspension/alignment tuning you would be crazzzyy fast out there.
Sasha is the man for the job.
