Does the GTS2CD Clutch for JZA70 need a Movement Alteration Kit?

Turn 14 lists no separate kit for the GTS2CD Clutch for JZA70 (TY021-BP6). OS Giken Japan lists its 1JZ-GTE Street Master clutches with the release conversion parts included, which is why no kit is named. Our team will confirm what comes in the box before the order is placed.

How much power will it hold?

OS Giken USA does not give a separate figure for the soft version. Its guidance is to choose the GTS2CD when the engine is well below 80% of the Grand Touring maximum, and it rates the GT2CD at about 650 lb-ft. OS Giken Japan places the Street Master range in its 400 PS class.

What does GTS2CD mean?

It is the OS Giken model code. GTS is the cover series, 2 is the number of discs and C is the 215mm disc size. D means the discs have damped hubs that soften driveline shock. Our team can help with any questions.

Is it easy to drive on the street?

Yes. The GTS is the soft version of the Grand Touring clutch, with a lighter pedal at the cost of some capacity, and OS Giken USA aims it at street and show cars that run well below the GT clutch maximum.

Does it fit the Chaser, Mark II or Soarer?

OS Giken Japan lists the GTS2CD for the 1JZ-GTE in the JZA70 Supra, the JZX90, JZX100 and JZX110 Chaser and Mark II, and the JZZ30 Soarer. Turn 14 lists this part number for the JZA70 Supra, so our team will confirm the release parts for your chassis before the order is placed.

Description

OS Giken GTS2CD Clutch for JZA70 Toyota Supra 1JZ-GTE, Grand Touring Soft Twin Plate

OS Giken’s GTS2CD Clutch for JZA70 Supra models is the soft version of the GT2CD Grand Touring twin plate, with two 215mm discs with damped hubs and a softer diaphragm spring. OS Giken USA says the soft diaphragm allows an easier, lighter pedal at the expense of torque capacity, and recommends it when the engine runs well below 80% of the Grand Touring maximum. For a mildly tuned 1JZ-GTE driven mostly on the road, it gives twin plate engagement with the lightest Grand Touring pedal.

When Soft Makes Sense

The GTS2CD Clutch for JZA70 cars follows a simple rule from OS Giken USA: if the engine makes well under 80% of the GT2CD rating of about 650 lb-ft, the soft diaphragm is a good fit. Above that, the GT2CD keeps the same smooth engagement with more clamping force.

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.
