Failure does happen in the suspension business. It's only when it's frequent or whengetting an engineer to look at it will require thousands of dollars and the item destroyed at the end. its not that simple , i know. i have delt with engineers on construction jobs where i designed some structural items. the owner of the vehilce is responsible for its safe operation here in the u.s. also the only thing the wheel base difference will affect is the akerman. i dont see where there would be a safety issue putting that front end under a mustang. btw lots of guys take old mustangs and chevys and put straight axles under the front and street drive them. if you can read a tape measure you can do a way better job then the factories +-1/8" tolerance. yep the tolerance on the old mustangs was 1/4".
i have never heard of a wreck occuring becaue of a suspension kit or modification. there have ben some factory recals in the last few years because steering shafts, steering u-joints, have failed. about a week ago it was reported that 5 ford f series pickup trucks had the steering box FAIL causing loss of control. the gov is investigating
something dramatic occurs that it becomes known. Here's one with a potential for
failure that they addressed (cast vs forged in this case)-
Front upper control arms on the 2005 Ford GT. That's an example that's definitely
known by the public. I'm not aware of any fatalities. Ford at that point may have
still had control of most/all of the 283 cars anyhow, but NHTSA makes you put the
notice out regardless.
I've been involved in the legal process AFA the aftermath of a wreck where high
performance aftermarket suspension parts were involved. You wouldn't want to
go there as a parts supplier. The only time the shark stops biting is when you can
show that a failed suspension part broke as a consequence of the accident and
wasn't a factor in causing the accident. It takes some cubic dollars to determine
As far as crash-testing, even the "Big 3" aftermarket parts programs do that. One
of the criteria of being a vendor to those programs is not only giving up your parts
for poking and prodding by their engineers but they do crash test them as well. It
is a significant time and dollar investment for both the vendor and supplied corporation.
