Can these studs be replaced with 1/2" studs? My Weld Pro Star 96 wheels require a Mag lug nut with a 1.310" shank length. I have not been able to find this lug nut to fit a stud any larger than 1/2". Thanks.

For the 5 on 5" bolt pattern hubs you can use studs 54546190 but you will have to spot weld them in place. This hub is made for a .695" knurl diameter and that stud has a .685" knurl. The stud is tight enough to center up fine but it will try to spin when tightening the lug nuts. For 5 on 4 3/4" bolt pattern hubs they require screw in studs 91048397. Those you will simply unscrew the 5/8" studs that are in the hubs and screw in these 1/2" studs.

Will this hub work with part number 91048323?

Sorry there is not a torque spec on the retaining nut. You need to tighten it just enough to provide some prelaod to the bearings. Use the same procedure for setting the preload on these bearings as you do front hubs/rotors.

Rotor mounting on the hub I am using a Wilwood 160-0483 on the 2255C hub and wanted to confirm the rotor mounting. The Wilwood rotor has one face straight and the other face the mounts are recessed. Want to confirm that the recessed face bolts to the hub such that the smooth face of the rotor faces towards the centre of the car - I.E. on your website the picture for the 160-0483 rotor, the face shown would bolt to the hub rotor ring. Am I right?

You can actually position the rotor either way for clearance and/or so that it fits your brake bracket. Usually I will bolt the flat face of the rotor to the hub so that it offsets the rotor as far inboard as possible. This will give maximum wheel clearance and air flow for cooling.

Thread length? When you say 2" of thread, is that 2" of thread from the drive flange face?

Yes, the Winters grand national hub kit uses a press in stud that has 2" thread length. Speedway offers replacement stud part #91048386 that is 3-1/4" long but we do not offer a 4" stud.

Wilwood 160-5863 Ultralite 32 Vane Drilled Vented Iron Rotor, 11.75 In
(Part #8351605863)
                        

When it comes to brake rotors, racers are constantly searching for the ultimate balance between the lowest weight and the ability to effectively manage heat. Decreased rotating weight in the drive line provides quicker deceleration under braking and quicker acceleration out of the corners. Lower weight also benefits handling with improved spring and shock control over the unsprung suspension mass. Wilwood's ULD-32 drilled iron rotors provides effective lightweight options for sprints, late models, modifieds, and other competition applications that race in low to medium temperature ranges.

  • Cast from premium grade, long grain carbon iron
  • Close tolerances on face and vane thickness
  • 32 straight vane casting provides superior heat management and long service life
  • Two row, 64 hole pattern - alternates between and directly over each vane
  • Each hole deeply chamfered to eliminate stress points
  • Rotating and unsprung rotor mass reduced by 12%
  • Left or right hand mounting locations

These scalloped iron brake rotors provide effective lightweight options for sprints, late models, modifieds, and other competition applications that race in low to medium temperature ranges. Steel rotors are typically found in lighter weight open wheel cars such as sprints and modifieds.  Speedway's premium 11.75" x .810" drilled scalloped brake rotor weighs only 5.07 lbs.

  • Scallop configuration provides greatest weight reduction on a vented straight vane iron rotor
  • Scallop machining removes as much as three pounds, or nearly 33% of the rotor mass
  • Vented castings provide increased cooling capacity over machined steel plate rotors
  • Improved structural durability over drilled rotor designs
  • Vented iron 
  • Inboard mounted (Sprints)

Note: Suitable for Light Dirt Racing applications. Scalloped Rotors are unsafe for street use.

Speedway Grand National Rear Hub Kits
(Part #91048400)

DRP Performance 10518 Grand National Rear Hub Bearing Spacer
(Part #91010518)
                        

These hub bearing spacers allow for consistent and precise bearing load every time the spindle nut is tightened, regardless of the torque applied. Without a bearing spacer, bearings are typically over tightened to prevent loosening during the race. With a bearing spacer installed, you can completely tighten the spindle nut and the hub will spin free every time. Bearing spacers save time, reduce bearing temperature and greatly increase wheel free spin, putting more horsepower to the wheels. You can feel the difference by simply pushing the car!

Testing has shown that the bearing spacer will make more difference than any “Low Drag” bearing set up currently available. When the spacer is used in conjunction with “Low Drag” Tapered bearings and seals, you will have the ultimate Low Drag set-up. These adjustable bearings feature a threaded sleeve and set screw to ensure you'll never have to worry about an over-tightened hub again!

  • 2.5” Short Track 5×5 Rear
  • Adjustable
  • 200%-300% more free spin vs. no spacer
  • Designed to fit all Grand National spindle and hub combinations
  • Makes servicing hubs simple & quick
  • Bearings run cooler
  • Saves time
  • Eliminates bearing “Spin” on spindle
  • Distributes side load evenly across bearings
  • Works on tapered and angular contact bearings
  • Once Set, typically never has to be adjusted unless bearings or hub is replaced
  • Instructions Included
  • Precision Machined in the USA
  • +/- .001” Minimum Parallelism
