Overview

The Maximum Motorsports MMIRSTR-2 is an IRS adjustable complete tie rod kit designed for the 1999-2004 Cobra. This kit replaces the stock rear tie-rod, which is a known weak point in the IRS system that can deform under moderate performance upgrades. The MM Tie-rod is more robust and stiffer than the stock unit, making it suitable for drag racing and open track use.

Beyond being a stronger replacement, the MM Tie-rod kit allows for bumpsteer adjustment. This is crucial for IRS-equipped Mustangs, which are sensitive to rear bumpsteer that can cause instability and asymmetrical handling. The kit offers adjustable bumpsteer at the outer tie-rod end and also allows for inner tie-rod pivot height adjustment, providing a wide range of tuning possibilities. It includes aluminum tie-rods, spherical rod-ends, adjustment spacers, and tapered studs.

Show original supplier description

The Maximum Motorsports MMIRSTR-2 is an IRS adjustable complete tie rod kit specifically engineered for the 1999-2004 Ford Mustang Cobra. It addresses a critical weakness in the stock Independent Rear Suspension (IRS) system: the rear tie-rod. Under moderate performance upgrades, the stock tie-rod can deform, altering rear toe settings and leading to significant handling and traction issues, particularly during launches or demanding track conditions. It's not merely a stronger component; it's a performance enhancement that allows for precise adjustment of rear bumpsteer. IRS-equipped Mustangs are particularly susceptible to rear bumpsteer, which can manifest as instability and asymmetrical handling. The MMIRSTR-2 kit enables fine-tuning of these characteristics by offering bumpsteer adjustment at the outer tie-rod end, similar to the MMIRSTR-1 kit, but also includes the ability to adjust the inner tie-rod pivot height. This dual adjustability provides a significantly broader range of bumpsteer tuning capabilities. This comprehensive kit allows enthusiasts to dial in their suspension geometry for optimal handling and predictability.
