These all-new front anti-roll bars are designed for the narrow front bulkheads of the T4 for fine-tuning. For easy recognition the anti-roll bars have laser-engraved markings to indicate bar thickness. The anti-roll bars are mounted using the included composite holders on the bulkheads and to the integrated anti-roll bar mounts on the suspension arms.
