Will this Supra rear big brake kit clear my wheels?

Clearance depends on wheel design. The Endless Racing 4 rear caliper is sized for wheels from 17 inches and this kit runs 332mm x 30mm rotors. Contact Bulletproof Automotive with your wheel specs and we will confirm fitment against the Endless wheel clearance data before you order.

What is included in the Endless 1933389 kit?

The kit includes two Endless Racing 4 rear calipers, a brake pad set, two caliper mounting brackets, two 332mm x 30mm three-piece rotors, and two stainless brake lines. It is a complete rear-axle system for the JZA80 Toyota Supra under one part number.

Can I run this rear kit with the factory front brakes?

The Endless Racing 4 rear kit installs independently, and Endless offers matching JZA80 front systems. Most builds upgrade the front axle first or together with the rear, since the front carries the majority of braking load. Contact Bulletproof Automotive if you want a matched front and rear setup for the Supra.

What pad compounds work with the Racing 4 caliper?

The Endless Racing 4 caliper runs 15mm-thick pads in the RCP066 shape. Endless supports its SSM, TR, MX72, and MX72 Plus compounds in this caliper, so the same Supra rear big brake kit covers street driving through circuit use on a pad change.

Is this kit a direct bolt-on for the JZA80 Supra?

Yes. Part number 1933389 ships with mounting brackets and stainless brake lines for the 1993-1998 JZA80 Toyota Supra rear axle, so the kit bolts on without fabrication. Bed the pads in dry conditions after installation to reach full performance.

Part number 1933389 is sold as one complete rear brake kit covering both rear corners: two calipers, two rotors, pads, brackets, and stainless lines, priced and shipped as a single system.

Endless Racing 4 Rear Big Brake Kit with 332mm 3-Piece Rotors for JZA80 Toyota Supra [1933389]

The Endless Racing 4 is a complete Supra rear big brake kit for the 1993-1998 JZA80 Toyota Supra, pairing forged four-piston rear calipers with 332mm x 30mm three-piece slit rotors, performance pads, caliper mounting brackets, and stainless brake lines for the rear axle. Endless builds the Racing 4 as a forged two-piece body at 2,500g per caliper with 27mm and 32mm piston pairs sized for rear-axle braking loads, so the JZA80 gains caliper stiffness and pad capacity behind an upgraded front system or as the finishing step of a full brake build. The rotors carry the Endless slit face that keeps the pad surface clean and friction stable as heat builds. Every component is designed and manufactured in Japan by Endless. Supplied as a complete rear-axle kit with 332mm x 30mm three-piece rotors in the Endless blue anodize caliper finish.

Features

Forged two-piece Endless Racing 4 rear calipers with paired 27mm and 32mm pistons sized for rear-axle braking loads
Fixed four-piston design for sharper response and even pad wear over the factory rear caliper
Slit rotor face continuously refreshes the pad surface and vents gas without the cracking risk of cross-drilled discs
Three-piece rotor construction reduces unsprung weight and manages heat through long sessions
Complete single-axle system: calipers, pads, brackets, rotors, and stainless lines under one part number
Direct bolt-on installation on the JZA80 rear axle with the included mounting brackets
Pairs with Endless front systems for the JZA80 for a matched full-car setup

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.
