This bar is fantastic!

I bought the rear sway bar from steeda and didnt notice anything at all in handling increases at higher speed driving. Bought the rear strut bar from fswerks, fixed the understeer issue immediately. Its not very noticeable at lower speeds but once you hit long sweeping corners you definitely feel the bar keeping the rear stable through cornering. Highly recommended for spirited driving or track use.

Stress Bar

For the price it's a great piece, you have to remove everything in the trunk to install it but its pretty straight forward. I'm very happy with the quality I highly recommended it!

Did more than I thought it would

This is apparently what my build was missing. Tightened the rear end up nicely. Feels more stable on the highway and long sweeping turns. Build: Bilstein Sport shocks, Ford racing springs, rear sway bar, front traction bar

Best Stress Bar and Best Value

Simple and quick to install, great build quality. Makes a noticeable difference. Compared to other really bulky and heavy bars around this was the best since I get to keep my cargo space and you can’t beat the price! Highly recommend
