Do the RS-R Sports-i Coilovers for A90 Supra need a warning canceller?

Yes. The Sports-i Coilovers for A90 cars replace the factory adaptive dampers, and RS-R states that its damper warning canceller is not included. Without the canceller an error message appears on the dash and the traction control off function will not work, so the canceller should be ordered with the kit.

How much lower will an A90 Supra sit on these coilovers?

At the RS-R preset the front sits about 30mm to 35mm lower and the rear about 40mm to 45mm lower than stock. Full-length adjustment allows more, with RS-R recommending minus 10mm to minus 55mm at the front and minus 15mm to minus 70mm at the rear for everyday use.

Is the Sports-i comfortable enough to drive every day?

RS-R designed the Sports-i for a firm, controlled ride on winding roads and at the circuit, and the 36-step adjuster lets the owner soften it for daily use. Drivers who want the softest ride and the factory mode switch are better served by the Best-i Active kit.

What is the difference between the RS-R Sports-i and the Club Racer for the Supra?

The Sports-i runs 8.0 kg/mm front and 14.0 kg/mm rear springs with 36 damping steps at each end. The Club Racer uses much stiffer 14.0 kg/mm and 18.0 kg/mm springs, 24 steps at the front and 36 at the rear and pillowball upper mounts, and is set up for the track rather than the road.

Can the dampers be rebuilt?

Yes. RS-R builds the Sports-i range in-house in Japan, so the dampers can be overhauled rather than replaced. Rebuilding restores the original damping, which is worth doing on a car that sees regular track days, and RS-R USA covers the kit for 1 year or 12,000 miles from purchase.

Description

RS-R Sports-i Coilovers for A90 / A91 Toyota GR Supra

RS-R’s Sports-i Coilovers for A90 / A91 Toyota GR Supra are built for owners who would rather set the damping themselves than leave it to the factory electronics. RS-R developed the Sports-i range for winding roads and circuit days, and the A90 kit pairs 8.0 kg/mm front and 14.0 kg/mm rear Ti2000 springs with monotube dampers that adjust through 36 clicks at each corner. Like every RS-R coilover it is assembled in Osaka and can be overhauled. It suits a driver who wants a predictable chassis for fast road use and occasional track sessions, and who accepts the RS-R damper warning canceller in place of the adaptive dampers.

Design and Performance

RS-R shapes the adjuster needle so the change per click varies across the range, spreading 36 steps across road and track settings. The monotube bodies hold a large volume of oil chosen to resist fade, and full-length adjustment keeps stroke constant at any ride height. The front runs as a true coilover and the multi-link rear keeps a separate spring.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
