A few days ago, this Porsche 718 GTS installed BONOSS Forged Lightweight Plus Wheel Spacers, front/rear 10mm(2/5 inch), PCD 5×130, CB 71.5 together with BONOSS Forged Grade 12.9 Extended Wheel Bolts. What do wheel spacers do? It allows for installing larger wheels and bigger brake calipers without breaking the fender. The special Porsche style three-fingered hub-centric design allows the wheel to be properly centered and locked, ensuring no vibration at high-speed rotation. These spacers and bolts are precision-engineered to fit the wheel to the hub with a 0.02mm tolerance accuracy and intent to improve handling performance, moreover, achieving an outstanding exterior.
