The Dynamic+ Sway Bar Kit pairs matched front and rear spring steel sway bars for the B9 and B9.5 Audi A4, S4, A5, S5, RS5 and A4 allroad. The hollow front bar is 28.6mm with thicker walls than the factory bar, while the solid one-piece rear bar is 23.8mm with two adjustment settings. 034Motorsport says the kit reduces body roll and sharpens steering feel more than a rear bar upgrade alone, and it was tested on the brand's own B9 A4 and S4 on street and track. The brand notes the ride is noticeably firmer than with its 22.2mm Dynamic+ rear bar, so the kit suits owners wanting a clear shift from comfort towards performance.
