A friend let me borrow his and another friend let me use his alignment rack to compare. It wasn't as accurate as his rack but pretty darn close. A lot of it is the user, it is much slower than the rack but especially for someone like me it would allow me to do it at home. Closest alignment...
I think it will be fine. Just expect to downshift when coming to hills. I would downshift manually instead of flooring it and have the sudden shock of high rpms. You'll learn to anticipate the hills and make everything smooth. Keep an eye on temps!
It's possible you might have to tow in third...
