If you're dialing in the rear suspension on a lowered 240SX and you want toe arms that hold their setting and clear the subframe, the ISR Performance Pro Series Rear Toe Control Rods are built for that job. This is the higher-end version of ISR's proven toe arms, with upgraded bearings, larger rod ends, thicker materials, and an angled design that gives lowered cars the subframe clearance a straight arm can run out of. They're built for both street and track use, and they're a direct step up from the Street Series.
What It Is
The ISR Performance Pro Series Rear Toe Control Rods are adjustable rear toe arms for the 1989-1998 Nissan 240SX (S13 and S14). They're the Pro version of ISR's toe control rods, which means Japanese spherical rod bearings, larger rod ends with dust boots, thicker materials, and added bracing over the Street Series arms. This particular version is angled, giving additional subframe clearance for lowered cars.
What It Does
Rear toe control rods set and hold the toe angle of the rear wheels, which is what keeps the car tracking straight and predictable rather than wandering or twitching under load. The factory arms use compliant rubber bushings that deflect under hard driving, letting toe change when you least want it. These replace that compliance with spherical bearings that lock the toe setting in place, so the alignment you dial in is the alignment the car actually runs, whether you're on the street or on track.
Pro Series Improvements
The Pro Series builds on ISR's Street Series arms with a set of upgrades aimed at better control and durability. The improvements over the basic arms are:
- Japanese spherical rod bearings for precise, deflection-free control
- Larger rod ends for added strength
- Rod end dust boots to keep contamination out and extend bearing life
- Thicker materials throughout
- Added bracing for rigidity
- Angled design for subframe clearance
Together these are the difference between an arm that feels tight for a season and one that stays precise and holds up to hard, repeated use.
Angled for Subframe Clearance
This version of the toe rods is angled specifically to clear the subframe on lowered cars. When you drop a 240SX, the suspension geometry changes and a straight toe arm can run short on clearance against the subframe at the new ride height. The angled design routes the arm around that interference, so lowered builds get the clearance they need without binding or contact. If your car sits low, this is the version built for that.
Fitment and Compatibility
These toe control rods fit the following:
- 1989-1994 Nissan 240SX (S13)
- 1995-1998 Nissan 240SX (S14)
They're a direct replacement for the factory rear toe arms on these chassis. The angled design is intended to provide subframe clearance for lowered cars.
Who This Is For
These arms fit a specific build. If you've got a lowered 240SX and you want toe arms that clear the subframe while locking in your rear alignment, the angled Pro Series is built for exactly that. If you drive your car hard on the street and the track and you want spherical bearings and thicker, braced construction rather than compliant factory rubber, this is the step up from the Street Series. If you've run ISR's basic arms and want the higher-end version with better bearings, larger rod ends, and dust boots, this is that upgrade.
These are not the right arms if you want to keep maximum ride comfort and minimum noise on a stock-height daily, since spherical bearings transmit more noise and vibration than factory rubber. If your car isn't lowered and you don't need the angled clearance, the standard Pro Series arms may suit you just as well.
Installation Notes
Professional installation and an alignment are recommended. These arms replace the factory rear toe rods and are adjustable for setting rear toe. Install them at your target ride height, then set your toe and get a professional rear alignment, since any change to the toe arms alters the car's alignment and driving on bad toe settings will chew through rear tires quickly. Support the vehicle safely, check that the angled arms clear the subframe through the full range of suspension travel at your ride height, and confirm all rod ends and hardware are properly torqued before driving.
