Reducing body roll keeps the contact patch flatter through a corner, sharpening turn-in and giving the chassis a more direct, connected feel without touching ride height or spring rate.\u003c\/p\u003e\n\u003cp\u003eBoth the front and rear bars are multi-hole adjustable, so the roll-stiffness balance between front and rear can be tuned to taste — more front bar sharpens turn-in and adds understeer, more rear bar rotates the car into corners faster. H\u0026amp;R manufactures the bars from cold-formed, hollow steel tubing and finishes them in a durable protective coating.\u003c\/p\u003e\n\u003cp\u003eSold as a Front \u0026amp; Rear Set, or as standalone Front Only \/ Rear Only bars for builders upgrading one end of the car at a time or replacing a bar individually.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eFront bar: 30mm, hollow, multi-hole adjustable\u003c\/li\u003e\n\u003cli\u003eRear bar: 25mm, hollow, multi-hole adjustable\u003c\/li\u003e\n\u003cli\u003eConstruction: cold-formed tubular steel, protective finish\u003c\/li\u003e\n\u003cli\u003eIncreases torsional stiffness front and rear versus the factory sway bars to reduce body roll\u003c\/li\u003e\n\u003cli\u003eDoes not change ride height, spring rate, or damping\u003c\/li\u003e\n\u003cli\u003eSold as Front \u0026amp; Rear Set, Front Only, or Rear Only\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eH\u0026amp;R adjustable sway bar(s) per the Configuration selected (Front \u0026amp; Rear Set, Front Only, or Rear Only)\u003c\/li\u003e\n\u003cli\u003eNew mounting bushings and hardware for the bar(s) included\u003c\/li\u003e\n\u003cli\u003eSee the fitting instructions supplied in the box for the full bill of materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003ch3\u003eAdditional Parts Required\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNone.\u003c\/strong\u003e H\u0026amp;R's sway bar kit ships complete with the bushings and hardware needed to install the selected configuration; the factory end links are reused.\u003c\/li\u003e\n\u003cli\u003eInstaller-supplied tools: jack and stands, standard hand tools, and a torque wrench.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eIllustrated fitting instructions are included in the box with the sway bar kit.
