Which cars is the 1.5-Way LSD for DC5 built for?

The manufacturer lists the 1.5-Way LSD for DC5 Integra Type R models of every year, and its US distributor files it under the Acura RSX. The RSX Type S gearbox is not named in the Japanese catalogue, so confirm your transmission with Bulletproof Automotive before ordering.

What does 1.5-way mean?

It describes how the differential behaves in each direction. On throttle it locks strongly to put drive down through both front wheels. Off throttle it locks more lightly, so the car still turns in willingly, and a moderate locking effect remains under braking to help keep the car stable.

Does the differential need a break-in period?

Yes. The manufacturer asks for a thorough break-in drive once the differential is installed. No distance or procedure is published for this unit, so follow the break-in your installer recommends and avoid hard launches and track sessions until it is done.

Can I install it myself?

The manufacturer recommends installation at a professional shop. Fitting a differential to a front-drive car means removing and opening the transmission, so it suits someone with the tools, the factory service information and real experience with gearbox internals. Bulletproof Automotive can suggest a shop.

Will it make the car harder to drive on the street?

The manufacturer designed it to avoid that. Its disc springs build lock with throttle input rather than relying on high initial torque, which the Osaka tuner says gives stability without difficult manners. Expect stronger drive out of tight corners and a more planted feel under power.

Description

J’s Racing 1.5-Way LSD for DC5 Honda Integra Type R and Acura RSX

J’s Racing’s 1.5-Way LSD for DC5 owners is the High Traction mechanical differential the Osaka Honda specialist builds for the K20A-powered Integra Type R, set with a 50-25 cam angle and a cold initial figure of 6.5 kg. It locks firmly on throttle and more gently when you lift, keeping some lock under braking to settle the car on corner entry. Disc springs, not heavy preload, shape the lock. On a front-drive car that spins its inside wheel out of slow corners this is a core upgrade; a car that never sees hard driving will not need it.

Design and Performance

A limited slip differential reads the speed and torque difference between the front wheels and restricts the open differential, sending drive that would escape through the unloaded wheel to the road. J’s Racing tuned the disc-spring pack so locking force builds with throttle input, aiming for stability without awkward manners.

Mechanical 1.5-way action: strong lock on power, lighter lock off power
50-25 cam angle specified by J’s Racing
Cold initial setting of 6.5 kg as quoted by the manufacturer

About J’s Racing

J’s Racing was established in Osaka in 1989, as VTEC engines and lightweight Civics and Integras were changing what a Honda could do, and it has built parts for Hondas ever since. The company develops engine response, suspension, braking, cooling and aerodynamics together as one system, then proves the parts in time attack, gymkhana, endurance and circuit racing. Its Fit lapped Tsukuba Circuit in 1’00.459, and its naturally aspirated AP1 S2000, the Maou car, became the company’s reference build for the Honda roadster. Every J’s Racing part is designed and tested in Japan, and J’s Racing USA in Carson, California handles distribution in the United States.

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.
