As I understand it, for solid rear axles, a watts link is the best setup you can put in. Anyone have one ? Who's kit did you buy ? How do you like it ? Pics of the install ? Any opinions (or facts) on who makes the best one ?
keep in mind the watts link only replaces the trac/panhard bar
it keeps the axle centered (left/right) as suspension travels, keep in mind a mustang rear suspension only travels 2-3"
if you have (keep) leaf springs a watts link would be completely useless
if you are running a triangulated 4 link there is no need for a trac/panhard bar or watts link
the only place a watts link would help is if you were running a 5 link strait upper and lower links, however i dont think you would be able to tell a differance between a watts link and a trac/panhard bar.
Landrover discoveries came with them stock.
my opinions only...
all good points. if you are keeping the stock leaf springs, dont spend the money on a watts link or even a panhard bar.
no one has asked what you're planning on doing with the car?
hard street driving? - panhard
autocross/roadrace? - panhard or watts (there are benefits to both)
benefit of the panhard bar is you can adjust your rear roll center after it's installed (with an adjustable mount). with a watts, once you install it, you can't change the roll center. watts does work slightly better at it's job of locating the axle, but for a serious car that's lowered and on stiff springs, the difference is marginal.
best handling live axle car I've driven (fully autocross prepped '69 camaro) had a panhard bar. that said, my '79 camaro (also fully prepped) has a watts, but I bought the car that way... both cars are 3 link setups.
What do I want to do with the car ? Thats a good question. I want it to handle. I want to have a car that is streetable but that I can take to the track and beat the absolute hell out of. Thats why I overbuild everything. When I eventually take this car to the track I don't want to have to worry about taking it easy so I'll be able to drive it home. I want to have fun and drive it like I stole it
