For your old man? I'd let him get used to driving a car period before you lay this on him. Because when it picks up a push, theres nothing you can do about it, especially with low power. Theres a number of things I would do first that will gradually increase the bite. First I would put an 11-12 inch shackle on the left rear with some kind of apparatus to change shackle angle, if you havn't already. Give me a call if you want to discuss it. Between that and one more thing I found he'll have twice as much bite.
