Need small favor, Measure length of rear track arm

I just don't understand why the designers of that part would make it to be adjustable. It's not a piece that will help by offering adjustment.

Now, adjustable control arms (for more front camber) or adjustable rear toe links (to increase the range of adjustment for lowered cars) would be really useful!

2 reasons i can think of are 1. if your car was in an accident which damaged the chasis slightly which caused the caster to change on a wheel, since you have caster adjustment, you can now correct that... For instance, you pull into a parking spot on the street and you bump your front wheel on the curb as you rolled into the parking spot, that can bend your toe link arm and or throw off your caster.

2. You have a specific setting you'd like to achieve and you'd like to get your caster further back to obtain the camber you desire... adjustments in caster can give you more negative camber.


and maybe a 3rd reason why they are made as adjustibles.... the plant which they are made only makes adjustibles out of stock piles of different lengths of metal rods and they dont have to CNC machine a part to exact spec... probably easier to machine a bolt head to the end of a rod of steel and tap in some threads. Probably all cost related.

The caster argument makes sense for the front, but these are rear arms we're talking about. You don't align a non-steered wheel for caster.

You're probably right about it being a cost issue. I'm just worried that people thing they need these to "tune" their suspensions....
