Kit Details

Our clutches are coated with a molybdenum traction surface and are specifically designed for the high temperature abuse situations that occur within the BMW differential. The clutches will retain the smooth limited slip engagement feel of the stock differential while providing long term durability. Our dog ear plates are precisely machined and hardened to ensure long term use.

We are commonly asked what's the best kit for individual needs. It's easy to choose the best kit for your needs using two simple steps:

1. Street v. Performance

A. Select the street option if your vehicle primary use is on the street. The street option best serves most of our customers. Our street kits are an excellent upgrade for your stock or modified street car. These kit versions offer similar preload (static lockup) and driving characteristics as a stock differential. By keeping excessive preload at bay, normal driveability is maintained even when adding additional clutches.

B. Select the performance option if your vehicle spends a good majority of time on racetracks, autocross courses or similar. Our performance kits are aimed specifically at customers who spend a good amount of time at the track or autocross course. The performance kit versions reduce preload (static lockup) for better in-turn performance during driveline neutral events. A small disadvantage to less preload is that the clutches will wear slightly faster due to being able to breakaway more easily.

2. Number of Clutches

A. Select two clutches if you must conform to class rules (racing, autocross, etc.) or have an absolute desire to keep your differential in stock configuation. NOTE: Most enthusiasts are best served purchasing a three clutch upgrage kit.

B. Select three clutches if you want a significant upgrade without sacrifice. The three clutch kits are our most popular products and are the best choice for the majority of our customers.

C. Select four clutches if you want the most traction available out of your differential. For forced induction setups, this is a must. This kit is also highly preferred by HPDE enthusiasts as it is a balanced with gobs of traction when needed.

Terms

Ordering & Payment:

Group Buys are a special order limited time offer. Pricing is exclusively available to those who participate and complete payment as required within the allotted time period. No rain-checks, including members who showed interested during the feeler period.

Orders can only be placed during the Open phase of a Group Buy. Payment information will be collected and authorized during checkout. Orders are authorized at the committed price. At the close of the Group Buy, the final paid member tally determines the discount reached. Order totals are adjusted down if required and payment is captured for the final amount due. Because all Group Buys are treated as special order, payments are captured prior to product shipping. Shipping and fulfillment times are listed for each Group Buy on the dashboard.

Free Shipping:

Free shipping is available to members in the 50 US states and Puerto Rico. For shipping outside the 50 US states and Puerto Rico, see International Shipping.

International Shipping:

Due to compliance complexities, we can not ship orders outside the United States. However we do serve many international customers! It is both less expensive and more convenient for our international customers to use one of the following two methods:

SHIP TO A FRIEND. Many our our customers have acquaintances in the United States. Simply place the order on our site and enter a shipping address within the United States.

USE AN INTERNATIONAL FORWARDING SERVICE. Using an international forwarding service is a great way to save money on transit and minimize the effect of duty / custom fees. While we do not have a preferred service, here are a few that some of our customers have used in the past:

https://www.shipito.com/
https://www.shippn.com/
https://planetexpress.com/
https://www.myus.com/

Please note that we do not have any relationship with any companies listed on this page. The individual consumer is responsible for choosing the service that best represents their needs. If you have a recommendation not listed above, please let us know.

Availability:

Some products may sell out. Availability is limited to vendor’s supply on hand. Orders will be fulfilled on a first-paid-first-fulfilled basis. Within 48 hours of placing an order request, the vendor will contact you if the product you ordered sold out, or went on backorder. You will have the option to modify your selection, accept the wait for new stock, or cancel or order.

Refunds, Exchanges, and Cancellations:

There are NO refunds on Group Buy orders. All orders are considered special order due to the unique production, fulfillment, and pricing of product. They do not share the same terms and conditions as traditional e-commerce purchases.

We recommend purchasing product at the retail price directly with the vendor or one of their affiliates if you would like a traditional retail sale.
