Take it to Drift King perhaps??
THey seem to know wot they're doing. And dont treat u like an idiot cuz you are young. I went to another shop in Bris ( i wont say their name) but lets say they have a big name and even sponsor events, and he looked at my car and didn't wanna touch it cuz it woz "too old" and is too hard to get bolt on stuff..
But Drift King guy seems pretty good and they have a nice clean workshop..
