Gr and 2015+ sti and wrx support brace. This brace is included with the gr front frame kit you do not need to buy this separately.
Its simple and effective. Replace the weak stock supports with a sturdy 4130 alloy steel tube brace, including a new rear LCA support plate. The front of our brace has a tapered socket and cone washer set up to force the brace and front frame in to one sturdy unit bridging the front and back of the LCA.
