Braking: My 2013 G37 Sedan felt loose under hard braking at medium to high speeds. This Rear Lower Power Brace did a great job at making my car feel more stable under all braking conditions. Traction: The car had almost no wheel slip when launching from a stop in DS mode. (Notes: 7AT, K&N Intake System, 235 width inexpensive tires). Cornering: It feels like a strut tower brace on the back of the vehicle. The brace keeps the rear in control when cornering and hairpin style turns too.

Still evaluating it. It’s an interesting feel though. I have an enhanced TQ management tune with my 7AT so it does very strong shifts above 3k RPM. So often if I accelerate at WOT the back of my car would slightly jerk to a side during the up shifts. But after installing this, I just noticed the weight transfer towards the back evenly. Quite interesting ????
