Vintage Venom LLC. has compiled a set of FAQs to help you locate the best product for your needs.  When determining the proper kit to place on your vintage Mustang or Cougar, make sure to read through these important faqs.

FAQ overview

What does "recessed wheel studs" in my hub mean?

There are two types of hub configurations.  One has the wheel stud heads sitting on the surface of the back side of the hub, the other has counter bores in which the stud heads sit recessed.  The two styles require different wheel studs be included with the kits.

Why is the "rotor spacer" used?

The spacer serves two purposes, it is designed and manufactured to optimize the position of the SN95 17"x8"x30mm wheel on vintage Mustangs while utilizing the stock drum brake spindle/hub and also positions the rotor appropriately for the late SN95 Cobra brake parts.

Why is the "rotor spacer" between the rotor and the hub and not behind the wheel?

The spacer is best located between the hub and the rotor. This maintains the direct interface between the two working surfaces (the wheel and the rotor) and simply serves as a hub modification. Additionally, the ARP stud knurls grab the spacer once installed making it essentially integrated with the hub. No more fumbling with wheel spacers every time you pull a wheel off..! Also, this design allows the spacer to be fully piloted by the original hub allowing the spacer to properly pilot the rotor and wheel concentric to the hub. Therefore, neither the rotor nor the wheel is relying on the wheel studs to determine their locations.

Does the spacer change my front track width?

Yes, however not by the amount of the spacer thickness. The deeper offset of the SN95 wheels compared to the original vintage Mustang offset keeps the track width change to a minimum. Your wheel center will only be moved out ½" per side from its stock location. Again, this is required to fit a 17"x8" wheel on the front without hitting the upper control arm, no matter how you go about it.

Why are the long wheel studs used, and is this a good idea?

They are used to accommodate the increased effective hub thickness due to the rotor spacer. Additionally, a longer fastener is actually a good thing. It provides an improved joint by having better torque retention and strain consistency than a short fastener. Except for the added cost, this is a plus! In addition, the high strength ARP studs are known as the leaders in the industry.

Adaptor bracket design, why one over the other?

Stiffness is the key to a successful bracket design. A caliper mount that lacks stiffness can lead to problems, even if it does not break. Deflections of the caliper mount can lead to excessive tapered wear of the brake pads, resulting in excessive pedal travel, and is a potential source for an assortment of brake noises.  A key contributor to deflection is bracket offset.  Does the bracket carry the load radially from the attachment mounts, or is it offset.  Any offset increases the torsional/twisting moment in the bracket, and results in deflection. 

The Vintage Venom brackets are beautifully radiused billet parts and are absolutely stunning!  They do not have offsets and each version of the bracket has been designed to its specific material properties.  While aluminum is sexy and light, it needs mass for strength.  Therefore, these billet aluminum beauties are almost an inch thick of T6061 aircraft aluminum! 

What is the difference between Wheel Offset and Back Spacing, and how do I determine what mine is?

Back spacing is the distance from the inboard bead of the rim to the hub mounting face. (5.758" needed)Offset is the distance from the centerline of the rim to the hub mounting face. (30mm needed)
