2.5 is not the ratio on these sport racks. 2.5 is the number of steering wheel turns from lock to lock. I thinks the ratio is more like 15:1.I put a quick ratio rack in my old mustang and would never go back. It's in the new project also.
The feel is things better. Changing lanes is effortless. I can't remember the ratio for sure... but I think it's 2.5 to 1.
I've got two sport racks (2.5 turn lock to lock), one on the LX and one on the convertible. Got them both at Autozone for roughly $70 each. I have had no trouble with either one of them.
