Strength is NOT the same as stiffness, that bar looks like it's keeping the rear toe changes in check, and possibly reducing the chance of metal fatigue cracking the welds further down.

It could be made of tinfoil so long as the stiffness was there, don't dismiss it just because the metal is thin - it could easily be increasing the local stiffness by an order of magnitude.

 

good to know thanks

 

I would keep it. While its thin looking at it from your vantage point, it's much stronger from a lateral perspective. It connects both sides of the suspension from below the differential, which sees quite a bit of load, especially with boost.

 

I had mine out for years and just recently put it back in. I didn't drive my car back to back with that as the only change, but when I was out, I never noticed anything funny.

Have mine off for 3 years now......with a 8.8 diff for a year and don't notice shit.....lol

 

I have had mine off for a couple years and have never noticed anything.
