I have mustangII rack in my dart, and the steering arms are shotened up a lot, to 2 1/4 turns lock to lock and about 45 degrees turn on the inside wheel. What this deal has done for me is allow me to make a snap correction at speed, and come out of a big slide ok. So as you can guess, I like fast ratios! Putting extra caster in really helps keep the car on track. Just don't overdo it. If you lose your grip on the wheel in a turn, it can do serious damage to some fingers.
