Does the STR2C Clutch for R32 and R33 cars need a conversion kit?

No. The STR2C Clutch for R32 and R33 GT-R models is a pull-type design that works with the factory pull-type release system. Several other OS Giken clutches for these cars are push-type and need a Movement Alteration Kit, so check the part number before you order.

How much power will it hold?

OS Giken USA rates the STR2C at about 575 lb-ft of torque, and the OS Giken Japan catalogue places the STR series in its 400 PS class. That suits a modified RB26DETT where pedal feel matters as much as clamping capacity.

What does STR2C mean?

It is the OS Giken model code. STR is the cover series, 2 is the number of discs and C is the 215mm disc size. There is no D on the end, which means the discs have solid hubs rather than damped hubs, for a direct and positive engagement.

Is it suitable for daily driving?

The STR series was designed for a lighter pedal than a factory clutch, which makes it easier to live with in traffic than many twin plate kits. Solid-hub discs can pass more driveline noise and shock than damped discs, so expect a more connected feel than stock.

Can the clutch be rebuilt when it wears?

Yes. OS Giken offers Overhaul Kit A for this clutch, with the discs, center plate, pressure plate and cover bolts, and Overhaul Kit B, which adds a new cover. Rebuilding with the matching kit restores the clutch for less than a complete new kit.

OS Giken STR2C Clutch for R32 / R33 Nissan Skyline GT-R, Pull Type

OS Giken’s STR2C Clutch for R32 and R33 Skyline GT-R models is a twin plate clutch built for the factory pull-type release system, so it goes in without converting the car to a push-type arrangement. STR is the OS Giken series created around pedal effort: OS Giken developed it after its endurance racers asked for a lighter clutch, because a heavy pedal wears a driver down over a long stint. The STR2C pairs two 215mm solid-hub discs with that lighter cover, and OS Giken USA rates it at about 575 lb-ft. It suits a modified RB26DETT that is driven hard on track and still sees regular use on the road.

Why Pedal Effort Matters

OS Giken Japan describes the STR series as lighter at the pedal than a factory clutch. On a GT-R that is driven in traffic between track days, or raced for long sessions, that lighter pedal makes a real difference to fatigue. The solid-hub discs give direct engagement and a positive bite rather than the softer feel of a damped hub.

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.
