Every Weld Racing wheel is made in Kansas City, Missouri, USA.
"Pad Height" refers to the back side of the wheel's center and the profile of the wheel's face (spokes in this case). The 15” S71 RT-S is available in 2 pad heights only (Low & Medium). RT-S wheel sizes 17”, 18”, & 20” are available in all 3 pad heights The low pad center is a relatively flat profile with the least brake caliper clearance. It has a maximum clearance of .89” at the peak of the spoke curvature. The low pad center fits drum brakes, drag racing brakes, and early disc systems into the 1980’s model cars. The medium pad center is a slightly curved spoke profile with increased brake caliper clearance. It has a maximum clearance of 1.19” at the peak of the spoke curvature and fits most cars from the late 1980’s through the 1990’s models with their larger disc brake systems. The RT Series wheels (WeldStar, Magnum III, Vektor, Vitesse, Woodward, and Classic) are built as a medium pad. The high pad center is a highly curved profile and has the most brake caliper clearance. It has a maximum clearance of 2.05” at the peak of the spoke curvature. It is for aftermarket road racing type brakes and the latest supercars fitted with Brembo brake systems.
Please refer to the Wheel FAQ & Tech in the Weld Racing website "Forums". Very detailed procedures and tips are listed.
7/16 Wheel stud = 75-85 ft-lbs 1/2 Wheel stud = 85-95 ft-lbs 5/8 Wheel stud = 130-140 ft-lbs 12mm = 90 ft-lbs 14mm = 110 ft-lbs Weld Racing does not recommend the use of lubricant when installing lug nuts.
The most accurate way to balance a wheel and tire is to balance the package on the balancer in the same manner that it centers on the vehicle. A hub centric wheel is a wheel that has the same hub bore size as the vehicle and centers itself using the center hole in the wheel. A lug centric wheel centers on the vehicle using the lug nuts allowing the wheel to fit many vehicles instead of a select few. All Weld Racing wheels are lug centric. This means that they require a lug-centric adapter during dynamic (spin) balancing. A lug centric adapter plate should be used in place of the centering cone. The fingers on the adapter plate must be properly positioned so they line up with the lug holes in the wheel. The approved lug nuts for the Weld Racing wheel model should be used to fasten the wheel to the lug centric adapter place. This is necessary to appropriately center the wheel on the wheel balancer shaft. If this is not done, the results will not be as accurate or repeatable. After the first 25 to 50 miles, re-torque all lug nuts.
On the 15x3.5 "anglia" and "strange" application wheels, yes. Contrary to previous multi-piece spindle mount models, this is not evident from the front of the current one-piece wheel models. Studs, washers, and jet nuts are provided in each wheel box to attach the rotor to the wheel. The 17x2.25 spindle mount wheel can not accommodate brakes.
The AlumaStar 2.0, AlumaStar PRO, Magnum 2.0, Magnum PRO, V-Series, WeldStar RT, Magnum III RT, Vektor RT, Vitesse RT, Classic RT, Woodward RT, and the 15" S71 have lug holes drilled to accept a 5/8" drive stud. The lug hole opening is drilled to .703". The Draglite, ProStar, and Rodlite have a lug hole opening of .687" which will not allow the use of a 5/8" stud without altering the size of the lug holes. This will affect the warranty. None of the 17" or 18" RT-S series products will accept a 5/8" drive stud.
