What kind of R34 is the GT2CD Clutch for R34 cars made for?

The GT2CD Clutch for R34 GT-R models is for a built BNR34 that is driven on the street, shown and cruised more than it is raced. OS Giken USA describes it as ideal for a show car that needs extra capacity with smooth, chatter-free manners.

How much power will it hold?

OS Giken USA rates the GT2CD at about 650 lb-ft of torque. That covers a substantially modified RB26DETT. Engines making far more than that, or cars used hard at the track, are better served by the STR or R series.

What does GT2CD mean?

It is the OS Giken model code. GT is 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.

What is the difference between the GT2CD and the GTS2CD?

The GTS2CD is the soft version of the Grand Touring clutch. It uses a softer diaphragm spring for a lighter pedal at the cost of some torque capacity. OS Giken USA suggests it when the engine makes well below 80 percent of the GT clutch maximum.

Can it be rebuilt when it wears?

Yes. OS Giken offers Overhaul Kit B for the GT2CD, 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. Our team can order it for you.

Description

OS Giken GT2CD Clutch for R34 Nissan Skyline GT-R, Grand Touring Twin Plate

OS Giken’s GT2CD Clutch for R34 Skyline GT-R models is the Grand Touring twin plate kit, one of OS Giken’s newest designs, and it is aimed squarely at a high-powered BNR34 that spends its life on the road. OS Giken USA describes it as ideal for a show car that needs a higher capacity clutch to get to and from concours gatherings. Its two 215mm discs use damped hubs to protect the driveline, and OS Giken’s floating pressure system is there to make engagement smooth and free of chatter. OS Giken USA rates it at about 650 lb-ft, enough for a substantially built RB26DETT.

Grand Touring Versus STR

The GT2CD puts comfort first, while OS Giken USA recommends its STR lineup for motorsport and dual-purpose cars. If the R34 sees track days, the STR2CD for R34 is the better start. If the engine makes well under the GT2CD capacity and an even lighter pedal appeals, the GTS2CD soft version is also listed.

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.
