You can drift without aftermarket helpers to the steering angle, I've done quite a bit of pavement drifting in the z. However more angle needs to be added asap to be competitive at all.
Its probably going to be a "make one" or find one that fits kind of thing. Mk1 Rabbits have similar ones that I've heard fit on z cars with modification, but don't quote me on that.
If you do that method carefully, it really isn't that bad lol. We heated the fender and then rolled mine that way, turned out 100% a-okay. Then again we went really slow and pulled up on the jack handle at each point for lots of roll.
I mostly did it to roll the inner lip.
I tried the corporate world, couldn't handle the BS. Now i'm my own boss being a grease monkey, definitely my favorite lifestyle. I'd rather be happy and have an okay amount of money than depressed and do nothing but work and have money.
