Product Description

RS-R spring kits are for Supra owners who want to close up factory wheel gap without moving to coilovers. Down Sus T215D gives the A90/A91 a milder drop, while Super Down T215S brings the car down further for a more pronounced stance.

The drop is not identical on every Supra. RS-R uses separate measurements for the 2.0T and 3.0T chassis, which is why the 2.0T has a different rear drop than the 3.0T. Choose the spring option based on how low you want the car to sit, then use the engine-specific figures above as your guide.

Installation Notes

Plan on a professional alignment after installation and once the springs have settled. Final ride height can vary slightly with trim, factory suspension condition, wheel and tire setup, and vehicle equipment. Super Down Sus has substantially less clearance than Down Sus, so check tire and wheel clearance before selecting that option.
