TRUE REAR VS DIVORCED
FastRoad Pro is available in True Rear or OEM / Divorced spring configuration. The AE86 Corolla was developed with a divorced suspension set up. The rear of the chassis spring is mounted on a separate adjustable spring perch compared to True Rear which has the spring installed as one whole unit throughout the entire chassis.
Not sure what’s the correct suspension set up for your Toyota Corolla AE86? Check out our True Rear VS Divorced break down below or contact us to find the best setup for your intended use!
Our divorced option is perfect for daily use with occasional canyon runs and track days. We wanted to develop a product that would not feel harsh or clunky at parking speeds or on the freeway. When you’re at the track, dial up the damping on the 24 position dampening knob and be rewarded with firm turn-in and even greater chassis control.
Custom spring rate or Swift Springs upgrades are also available for FastRoad Pro divorced setups. Please note: 6K rear is not available for the Swift Springs upgrade.
For competitive use, True Rear can offer easier spring rate tuning options while providing performance advantages such as higher roll stiffness for a given spring rate and lower overall weight.
Rear chassis reinforcements for True Rear setups are recommended but not required. It’s up to the customer to decide if the chassis is solid enough to have the weight of the rear of the vehicle resting on the rear shock tower mounts!

We never settle for less, so why should you?
One of our core principles is that test fitting our suspension to a car is not enough. We will never release any application before ensuring our valving, stroke, and handling balance meet our very high standards. Few of our standard procedures include the following: model the OEM suspension geometries, understand the chassis’ motion ratios, then select natural frequencies and valving profiles that best match the car. Finally, we dyno test the shocks before fitting them to a live vehicle. We do all of this to ensure you are completely blown away after driving on our suspension systems.
We have tested and developed multiple setup iterations for the AE86 chassis to find the perfect blend of performance and daily usability. We did this by understanding details others seem to ignore, such as the live rear axle. The rear of the car with the heavy live axle is often where grip is limited the most. To correct this, we increased rear stroke to provide sufficient bump and droop travel and valved the dampers for the live axle’s weight. We offer both divorced and true rear for the FastRoadPro™.
