Description

Toyota A90 GR Supra True Rear (19+) BC Racing DS coilover kit 5/5 kg/mm

The BC Racing DS coilover kit Supra A90 True Rear (part number C-197-DS-DH) is a coilover kit adjustable in height and damping, also simply called a coilover, for the Toyota GR Supra (A90), from model year 2019, in True Rear version. The spring rate is 5 kg/mm front and 5 kg/mm rear.

The DS True Rear for the GR Supra combines track-focused damping with a complete strut at the rear. Where BC Racing’s standard A90 kits (C-165) keep a separate spring and damper at the rear, on this Rear Integrated version the spring sits around the damper, just like at the front.

The monotube dampers have a digressive piston that damps more firmly during slow body movements (0 to 50 mm/s), a satin chrome damper body and 30-click damping adjustment. Pillowball top mounts or camber plates are fitted front and rear.

Key benefits

• True Rear: the spring around the damper at the rear too, with the height set directly on the thread.
• Digressive piston: firmer damping during slow body movements.
• Pillowball top mounts front and rear: or camber plates, on all four corners.
• Ride height independent of spring preload: lower the car while the preload stays the same.
• 30-click damping adjustment: compression and rebound together per damper.
• Spring rate 5/5 kg/mm: the same as the BR True Rear for the A90.
• Satin chrome damper body: with concave lower lock ring.
• Rebuildable: the dampers can be rebuilt.

Fitting and delivery

The kit is vehicle-specific and replaces the original dampers and springs. We recommend having it fitted by an experienced mechanic. Please note: BC Racing specifies that the body shell must be reinforced before fitting a True Rear kit. After adjusting, allow for a new wheel alignment, because camber and toe change as well. The delivery time is 1 to 2 weeks as long as the manufacturer has stock. If BC Racing temporarily has the kit out of stock, you can still order it and we will keep you informed of the delivery date.

Why choose this DS coilover kit Supra A90 True Rear?

Frequently asked questions

What is the difference between the BC Racing DS True Rear and the BR True Rear for the Toyota GR Supra A90?

The DS has a digressive piston and is track-focused, the BR a linear piston for mainly road use. Springs (5/5 kg/mm), top mounts and the True Rear construction are the same. If you often go on track, the DS coilover kit Supra A90 True Rear is the better match.

What does True Rear mean on the BC Racing DS coilover kit for the Toyota GR Supra A90?

True Rear means that the spring also sits around the damper at the rear, so you set the height there directly on the thread. BC Racing also calls this Rear Integrated. The standard DS for the A90 (C-165-DS-DA) keeps a separate spring and damper at the rear.

Does the BC Racing DS True Rear coilover kit fit every Toyota GR Supra A90?

Yes, BC Racing UK approves this kit for the rear-wheel drive GR Supra A90 from 2019 and lists no exceptions. BC Racing does specify that the body shell is reinforced before fitting.

Is the BC Racing DS True Rear coilover kit for the Toyota GR Supra A90 also suitable for the BMW Z4 G29?

No, this True Rear kit only fits the GR Supra A90. For the BMW Z4 G29, which shares its platform with the A90, BC Racing supplies its own kit under an I-97 part number.
