Materials and Safety
Autopower manufactures the majority of roll bars and cages from seamless DOM or ERW mild steel tubing. This type of tubing is designed not to break in the event of a crash. It will deflect and bend while maintaining the integrity of the roll bar or cage. The addition of a roll bar to your car not only adds protection, it can add substantially more chassis stiffness, improving the car's handling characteristics.
Autopower Paint Finishes
Most steel products are sprayed with an industrial grade gloss black cover coat for rust protection. EXPECT some paint damage during shipping. You may want to refinish products before final installation. It is best to check fit and drill all holes before you repaint. There is NO paint finish guarantee. |

Maximum Motorsports Drag Race Roll Bar
Increase both safety and the rigidity of your Mustang's chassis with a Maximum Motorsports Roll Bar. Intended for the rigors of drag racing, these MM roll bars conform to NMRA and NHRA rules. Designed to fit with the stock Mustang interior, MM roll bars are also suitable for street-driven cars, especially if swing-out door bars are selected.
To keep delivery costs to a minimum, MM designed these roll bars to ship with the rear braces detached. This requires a minimal amount of welding during installation to secure the rear braces to the main hoop. For hardtop Mustangs, during installation the rear braces are bolted to the main hoop. This keeps the rear braces precisely aligned to the main hoop, allowing all welding to be done before the roll bar is installed in the car. This means you do not need to remove your car's interior to avoid damaging it while welding. To conform to the NHRA and NMRA rules, a qualified welder must use either the MIG or TIG welding process to weld the rear braces to the main hoop. MM's recommends that you get your own copy of the latest NHRA rules by calling them at 626/914-4761.
The convertibles have a slightly different installation procedure. To provide a good structural attachment point for the roll bar's rear braces, MM include reinforcement plates for the convertible chassis. These are welded into place behind the rear seat. These reinforcements increase the strength of the convertible chassis at the attachment point of the rear braces. With a convertible, the top can be lowered and stowed during installation, which then provides easy access to protect the interior and complete the required welding. After all welding is completed, the roll bar still bolts into place, and can be removed from the car as a complete unit. |
|
 |
* Made of 1-3/4" x 0.134" wall DOM seamless tubing (much stronger than the more commonly used ERW seamed tubing).
* MM's rear braces are straight, with no bends. The NHRA rules prohibit any bends in the tubing of the rear braces.
* Includes a harness-mount/seat-back brace for shoulder harness attachment and seat back reinforcement.
* MM's harness-mount/seat-back brace is available pre-welded (meets NHRA rules), or as a bolt-in version for easy removal (bolt-in is not NHRA legal).
* Contour-hugging 6" x 6" mounting pads with backup plates, better than any you've seen, sandwich the unibody for safe and strong mounting.
* The front seats are accessed using our bolt-in or swing-out door bars. While both bars meet the NHRA rules, the swing-out door bars pivot outward, parallel with the doors, for easy entry. They can also be completely removed from the car in a matter of seconds! The bolt-in door bars are designed for easy initial installation (no welding), but are not intended to be removed.
* Unlike some roll bars, our rear braces do not extend rearward of the centerline of the rear axle. This design maintains a crush zone at the rear of the car for optimum safety.
* Unlike most other roll bars for hardtop Mustangs, MM's rear braces mount to the strong compound curve of the rear inner wheel well, leaving space for the back seat. |
|
|
MM's maintains an inventory of all standard roll bars. MM roll bars are shipped by truck freight, with shipping charges prepaid. MM roll bars are uncoated, bare steel. For a high quality finish, the installer should paint or powder coat the roll bar after the welding is completed. A convertible's tonneau cover will not fit after a roll bar installation. Will not fit convertibles with light bars. |
|
Chro-Moly Steel
MM does not use Chro-Moly steel tube. Because of the metallurgical properties of Chro-Moly, any welded area will have a higher concentration of stress than the surrounding, non-welded area. This concentration of stress can lead to the failure of the welded joint unless properly relieved with a post-weld stress relieving treatment.
Because the MM roll bar design requires that the two rear braces for the main hoop be welded during installation, if MM's used Chro-Moly tubing those welded joints would need to be properly stress relieved before final installation of the roll bar. MM consider it to be too difficult and cost-prohibitive for the customer to find a properly trained and certified technician to perform the required stress relieving.
Bolt-in vs. Weld-in Installation
The MM Roll Bars for hardtop Mustangs are designed to bolt to the chassis, without welding. With a bolt-in installation, the floorpan is sandwiched between the roll bar mounting pads and the back-up plates underneath the floorpan. There is a significant clamping force between the two pads, which provides a very secure installation.
While they may be welded-in, allowing a reduction in weight over a bolt-in installation because there is no backup pad on the other side, there are serious issues to consider. If the installer is not in the "expert welder" category, he may burn through the sheet metal of the chassis.
The MM Roll Bars for convertible Mustangs require that some welding to the floorpan be done. Someone who is in the "expert welder" category is required for installation of a convertible roll bar. |
