Rear Crossmember Mount Inserts Subaru BRZ + Scion FRS 2012-
These Rear Crossmember Mount Inserts from SuperPro will reinforce the soft original crossmember bushings on several Subaru models, including the 2014 Forester and 2015 WRX STI. These polyurethane inserts are the easiest way to eliminate excessive deflection in the subframe bushings and reduce the chance of wheel hop in your Subaru.
Firm Subframe = Less Wheel Hop
The rear cross member is part of the subframe that is responsible for holding the differential in alignment. The bushings that connect the cross member and the subframe are made of rubber which will deflect when you hammer the gas or brakes. This deflection can also cause the rear tires to lose and gain traction rapidly (wheel hop) when you take off from a dead stop or power through a turn. Rubber bushings are excellent at absorbing vibration but they also allow the cross member to shift and can throw off the alignment of your drivetrain.
If your Subaru is a dedicated track car then you might consider replacing those rubber bushings with metal mounts but if you have a bumpy Erath County commute like the folks at DST, then solid mounts will make the ride nearly unbearable. New rubber bushings will restore your ride to factory settings but what if there was a better option?
Performance + Comfort
To keep your daily drive smooth and still get the power to the wheels at a green light without the risk of the rear tires bouncing, you can install SuperPro's polyurethane rear cross member inserts. These polyurethane inserts will bolt onto each end of that existing bushing and firm up the connection without having to replace the entire bushing. Polyurethane is a much more durable material than rubber and has the vibration absorption qualities that metal mounts lack. This means the cross member is firmly held in place, giving you that race car rigidity in the subframe, but still taking the harshness out of your commute.
These polyurethane inserts are backed by SuperPro's lifetime warranty that includes racing and offroad applications, and we here at DST will handle that warranty for you in-house.
