Whiteline Adjustable Rear Lower Control Arms WRX 12-26 | KTA216A

Whiteline KTA216A replaces both factory rear lower control arms with adjustable stamped-steel assemblies. The pair uses cam-bolt and eccentric-bushing adjustment to provide approximately ±2.5 degrees of rear camber correction, useful after lowering when the factory range cannot restore the desired alignment. Whiteline’s vehicle selector lists the kit for WRX applications through 2026, including Premium, Limited, and GT configurations. The kit includes two arms and adjustment hardware and is distinct from the heavier-duty turnbuckle-adjusted KTA139A. No engine calibration is required. Installation takes roughly two hours according to Whiteline and must be followed by a professional rear/four-wheel alignment and fastener recheck.
