Who should choose the GTS2CD Clutch for R34 cars?

The GTS2CD Clutch for R34 GT-R models suits a moderately tuned BNR34 that is driven on the street or shown, where the lightest possible pedal matters more than maximum capacity. OS Giken USA suggests it when engine torque sits well below 80 percent of the GT2CD maximum.

How much torque can it take?

OS Giken USA does not publish a separate figure for the GTS2CD. It explains that the soft version gives up some of the GT2CD capacity of about 650 lb-ft for its lighter pedal, and recommends staying well below 80 percent of that maximum.

What does GTS2CD mean?

It is the OS Giken model code. GTS is the soft version of the Grand Touring cover series from the Street Master family, 2 is the number of discs, C is the 215mm disc size and D means the discs have damped hubs to soften driveline shock.

Is it suitable for track days?

OS Giken USA recommends its STR lineup for pure motorsport and dual-purpose cars, so a BNR34 that sees regular track use is better served by the STR2CD. The GTS2CD is aimed at street and show cars where comfort comes first.

Can it be rebuilt when it wears?

Yes. OS Giken offers Overhaul Kit B for the GTS2CD, which replaces the wearing parts and includes a new cover. Rebuilding with the matching kit restores the clutch for less than the cost of a complete new kit, and our team can order it for you.

OS Giken GTS2CD Clutch for R34 Nissan Skyline GT-R, Grand Touring Soft Twin Plate

OS Giken’s GTS2CD Clutch for R34 Skyline GT-R models is the soft version of the Grand Touring twin plate clutch, built for a modified BNR34 whose owner wants a lighter, easier pedal than the regular Grand Touring kit. It swaps in a softer diaphragm spring, trading some torque capacity for a lighter pedal, and OS Giken USA suggests it when the engine makes well below 80 percent of the regular Grand Touring clutch maximum. Like the GT2CD, it uses two damped 215mm discs and OS Giken’s floating pressure system for smooth, chatter-free engagement, which makes it a natural fit for a show or street R34.

Choosing Soft or Standard

OS Giken USA rates the regular GT2CD for R34 at about 650 lb-ft. The GTS2CD gives up part of that capacity for its lighter pedal, so it makes sense on moderately tuned cars. For track use or racing, OS Giken USA recommends its STR lineup instead, such as the STR2CD for R34.

Features

Softer diaphragm spring for a lighter pedal
Two 215mm discs with damped hubs for driveline protection
Floating pressure system for smooth, chatter-free engagement
Part of the OS Giken Street Master family
Rebuildable with OS Giken Overhaul Kit B

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.
