Alloy wheels (also known as rims) are automobile (car, motorcycle and truck) wheels which are made from an alloy of aluminium or magnesium (or sometimes a mixture of both). They are typically lighter for the same strength and provide better heat conduction and improved cosmetic appearance.
The Sportec tuning firm released the SPR1 FL based on the current 997Porsche 911Turbo with a facelift. It is the successor to the SPR1 R, featuring a new semi-sequential gearbox, LED taillights, rear bumper, and side mirrors. Performance numbers stayed relatively the same, however are still an impressive 858 PS and 880 Nm of torque. The new FL in the name comes from a Smooth Flow intake manifold holding two injectors per chamber.
