The drilled and slotted design helps reduce brake fade by allowing gases and debris to escape, while the vented rotor construction promotes better heat dissipation. The zinc silver hat finish provides corrosion resistance, extending rotor life under typical driving conditions.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor is vented and directional, optimized for the Pontiac Fiero. It measures 264 mm in outside diameter and 47.5 mm in overall height. The rotor’s nominal thickness is 18.92 mm, with a discard thickness of 17.3 mm, ensuring safe replacement intervals. The rotor includes five 14 mm bolt holes arranged on a 100 mm bolt circle diameter, matching the Fiero’s hub specifications. The rotor surface is plain finished with a slotted and drilled pattern to improve braking response and reduce heat buildup. Additionally, the zinc silver hat finish and rust-resistant coating protect against corrosion.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRestores braking performance on Pontiac Fiero vehicles with worn or damaged rotors\u003c\/li\u003e\n\u003cli\u003eReduces brake fade during aggressive or repeated braking\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation to prevent rotor warping\u003c\/li\u003e\n\u003cli\u003eHelps maintain consistent brake pad contact and stopping power\u003c\/li\u003e\n\u003cli\u003eProtects against rust and corrosion for longer rotor life\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor thickness is above the discard thickness of 17.3 mm before installation. The rotor is directional; install with the correct orientation to maintain optimal performance. Verify bolt hole alignment with the 5-lug, 100 mm bolt circle pattern on the Pontiac Fiero hub. Clean the rotor surface before mounting to remove any protective coatings or residues. Use proper torque specifications for lug nuts to avoid rotor damage.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the 631-52009R rotor to meet industry standards for durability and performance. The rust-resistant coating and zinc silver hat finish contribute to corrosion protection.
