No I haven't driven one with factory power assist. Only one I have driven is the one I recently got Yeah not sure if I can justify the cost of the borgeson setup... it is a bit spendy. But I have been reading up on the alternative setup's members are doing, some are more affordable so might go end up doing similar. This car is my daily driver so I need to get some issue's fixed first
The factory power assist is super strong, too easy to turn especially at speed. The borgeson unit is pricey but the box retains the original steering geometry, and there isnt that much modification required. The biggest drawback I have seen to the aftermarket rack and pinions for these cars, unless you go with a full mustang II front suspension(or fox body style) you have the potential to loose a few things, turning radius and ground clearence are the two biggest issues so if you are looking at lowering your car that has the potential to be an issue. And surprising enough as common as the rack and pinion units are, i didnt find an aftermarket bolt on setup cheaper then the borgeson setup. I know there is one or two members on here that have gotten something like chevy cavalier rack and pinion working on their car, but they have allot of time invested in making the bolt on structure and getting the correct geometry for it to function properly...and it sounds like you are lacking in time so that might rule that out as an option too... Yeah here is the post on the Cavalier/grand am rack and pinion setup http://mmb.maverick.to/showthread.php?t=71351&highlight=rack+pinion+steering
Thanks markso125 for all the information. The borgeson unit is sounding better and better all the time.
My car has factory ps. I don't find it too sensitive at speeds unless it's windy. Since I hve owned the car 2 1/2 yrs I have only had the pump rebuilt and "header drop bracket" rewelded to the frame. So far there have been no other issues - Yet. I don't drive the car over 75mph unless passing someone, so, I can't say how sensitive it wud be at 100. That won't be a problem cuz don't plan on driving it 100. Anyway, what may seem like not much steering effort for one, may feel just the opposite to another. If/when I start to have lots issues w/ the fac steering, my next move will be the Borgensen setup. I talk to the Borgensen folks at the NSRA North, in Kalamzoo, Mi. last fall an impressed w/ the setup. I also talk to a guy who had one on his 68 Stang and he had nothin but gud things to say abt the improvement over factory. I don't plan on giving up my pw steering for any reason and I only use the car as a hobby. If I used it daily I wud'nt ever consider removing it. jmo
