RTR Tactical Performance Coilovers (15-23 Non-MagneRide) - 1598-0420-01

Learn More

Steeda's 555-8175 front drag racing coilovers are a great way to improve the performance of your 2015+ Mustang at the track. These adjustable coilovers allow you to fine-tune the suspension and dial in your set up for faster times and quicker launches.

Improved weight transfer. The coilovers feature adjustable rebound to help you dial in weight transfer when you launch your Mustang so that you maximize traction. The coilover uses Ultra-High Travel (UHT) beehive springs that will not bind when you Mustang's front end comes back to earth.

Flatter launching. Adjustable ride height helps you achieve flatter launching and helps you corner balance your S550. The ability to fine-tune the Steeda coilovers lets you shave down your 60 foot times and maximize performance.

Mean look. Dropping the front 1.5", the Steeda coilovers give your Mustang an aggressive look at the track.

Spring rate to match your build. If your Mustang is naturally aspirated, we recommend running the 125 lb. coilover spring. If your Mustang uses forced induction, select the 150 lb. or 162 lb. spring in the dropdown.

Features & Benefits:
Flatter launching
Aggressive look
Better transfer
UHT beehive springs
No binding
Adjustable rebound
0 to -1.5" adjustable ride height
