How low will the GS sit on the RS-R Black-i Coilovers for JZS160?

RS-R Japan does not publish preset height figures for the Black-i Coilovers for JZS160 cars. Ride height is set during installation within the full-length range, and the final figure depends on wheel and tire size and on keeping the tires clear of the body at full compression.

Can the Black-i spring rates be changed on the GS?

Yes. RS-R Japan lists a selectable range of 14 to 24 kg/mm at the front and 12 to 20 kg/mm at the rear, with 18.0 kg/mm and 16.0 kg/mm as the recommended rates. Changing rates changes the ride height, so the car should be set up again afterwards.

How firm is the Black-i compared with the Sports-i on the JZS160 GS?

Firmer. RS-R built the Black-i for the lowest ride heights, with short-stroke dampers made for each model, high spring rates that keep the tires away from the inner fenders and aero parts, and a firm damping setting that controls those springs. The JZS160 GS will ride stiffer than on a Sports-i kit, which suits owners who put stance first.

Can the JZS160 GS dampers be rebuilt when they wear?

Yes. RS-R assembles the Black-i range in-house in Japan, so the dampers on this JZS160 GS kit can be overhauled to restore their original damping rather than replaced. Bulletproof Automotive can arrange the overhaul with RS-R USA, which keeps the original valving and spring rates for the car.

Should the RS-R coilovers on the JZS160 GS be installed by a shop?

It is the safer choice. Fitting coilovers involves the suspension mounts, hubs and brake lines, and the JZS160 GS needs a wheel alignment afterwards. A shop familiar with the car will also set the ride height evenly side to side and torque everything to specification before the alignment is done.

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.
