UMI Performance 99-04 Ford Mustang Upper & Lower Adjustable Control Arms

UMI Performance is known for making well-built suspension components that help you get the most out of your vehicle, especially when you're pushing it on the track or autocross course. This complete kit includes both their single adjustable lower control arms and their on-car double adjustable upper control arms, designed specifically as direct bolt-on replacements for your 1999-2004 Ford Mustang. These arms are built to tackle common issues like wheel hop, which can really hurt your acceleration and tire wear, and they'll help you dial in your suspension for better cornering and more consistent track times.

The upper control arms are a standout feature here because they offer double adjustability right on the car, making it simple to fine-tune your pinion angle without having to remove them. This is a huge time saver when you're making adjustments at the track. Both sets of arms use high-quality materials for strength and durability. The lower arms are constructed from DOM mild steel tubing with a 0.120-inch wall thickness, while the upper arms have solid 0.250-inch mild steel mounting points. You'll find QA1 spherical rod ends with a Teflon/Kevlar lining for smooth, quiet operation, and Energy Suspension polyurethane bushings that offer a comfortable ride while still providing solid control. The kit also includes CNC-machined aluminum step bushings with zinc-plated steel sleeves.

Installation is straightforward, designed as a simple bolt-on process that should take about an hour, and you can even use your original hardware. This kit is a solid choice if you're looking to significantly improve your Mustang's handling and traction, especially for performance driving.
