Back Orders

You will be informed of any item that may be temporarily out of stock and its estimated shipping date. Unless customer instructs otherwise, an item placed on back order will be shipped as soon as it is available. If a back ordered item is less than $99, you will be responsible for the shipping cost.

Sales Tax

I haven't been charged sales tax in the past. Why now?
The laws around charging sales tax for products are changing due to a recent Supreme Court Decision, and for this reason we must charge sales tax in your state.

States that are currently being charged sales tax are below:
North Carolina

How much sales tax am I being charged?
The tax rate varies by location and is in accordance with your state and local laws.

What if I am tax exempt?
Please e-mail your appropriate state exempt-sales certification to

What is use tax?
Even if your purchase is not subject to sales tax, you may be required to pay use tax. Use tax is similar to sales tax; the difference is who pays the state. When you are charged sales tax, the merchant (RJ Race Cars, Inc.) pays the sales tax to your state. When you are not charged tax on a taxable purchase you may be responsible for paying the use tax to your state at the same rate your sales tax is collected. 

For more information you should contact a Tax Professional or your states Department of Revenue.

I have additional questions, who can I talk to?
Please e-mail

Why is your competitor not charging sales tax?
RJ Race Cars, Inc. is complying with state laws and is unable to comment on the guidelines/compliance of other businesses. Failure to pay sales tax could result in state governed taxation at a later time.

Shipping Policy

Please refer to the UPS shipping map for approximate delivery times. We reserve the right to refuse shipment to any address. Please note that some carriers will not deliver to a PO Box. We reserve the right to ship via truck freight on large orders at our discretion. Truck freight will be used to ship items that are too large for standard service. Due to carrier restrictions, we are unable to provide air services for some items in our catalog. Hazardous materials will be shipped at an additional fee depending on the item and shipping selection. The FOB locations for drop shipments are dictated by our suppliers. All other items are FOB Galesburg, IL. Additional handling charges will be applied to all orders using an alternate carrier. However, if you still wish to use an alternate carrier (i.e. FedEx, DHL), you must contact our shipping manager directly for special request and authorization. Your request will be approved or denied. After receiving approval from our shipping manager, the customer is responsible for all arrangements for use of these alternate carriers. This includes but is not limited to, contacting the carrier to schedule the pickup and pre-payment to the carrier for the shipment using the customer's carrier account or customer’s credit card. Any claims for service failures or damages when using an alternate carrier are the responsibility of the customer.

Oversized Items

The shipping charges for all ground and air packages are subject to oversize and dimensional weight charges, which are more expensive, and may differ from the charges for the actual weight of the package. This applies to all packages and is very common especially in larger lightweight parts. For example, a hood scoop package may weigh 15 pounds, but when oversize or dimensional weight is calculated, you will be charged for a package that is based on 97 pounds. Please keep this in mind.

Refused Shipments

The customer shall be liable for any costs incurred from any refused shipment(s). RJ Race Cars, Inc. will be reimbursed for this expense before any further shipments will be permitted.


Inspect your order upon receipt. Claims for damages, open or concealed, must be made immediately to the delivery company. Bring any damage to the attention of the delivery person and make a written notice. If a shipment is damaged, keep the box and packing materials for carrier inspection. Take photographs if possible. Claims for shortages or incorrect items must be made to RJ Race Cars, Inc. within five days of delivery.

Return Policy

Quarter-Max will accept items purchased from us, that are sellable as new, for return or exchange within a period of 30 days from the date of the invoice, except for electrical devices, books, software, special orders, and custom built parts. Other exclusions may apply. We do not refund shipping or handling charges. After 30 days, we will accept only defective parts for repair or exchange at our discretion. Coil springs can be exchanged at our discretion, as long as they are returned in sellable condition with no rust or scratches. All returns are subject to a 20% re-boxing and re-stocking charge.

Any items which have been used, modified, altered or returned in such a condition as to not be resellable will not be accepted and no credit will be issued. Items to be exchanged must be in our possession and inspected before we can send out the exchange parts without charging you for the item(s). If you require the part before this process can be completed, we will be glad to ship the new item billed to your credit card and then issue the credit once the original item returns to us in good condition. Before returning any item for credit or exchange, you must call to obtain a Return Merchandise Authorization (RMA) number. Please have your invoice handy when you call to get your RMA number.

Privacy Policy

Thank you for visiting (our "Site"). We appreciate the opportunity to interact with you on the Internet and are committed to protecting and safeguarding your privacy. The purpose of this Privacy Statement is to inform you about the types of information we might collect about you when you visit our Site, how we may use that information, whether we disclose it to anyone, and the choices you have regarding our use of, and your ability to correct, that information.

What Information We Collect and How We Use It

Any information we collect on our Site generally falls into the following two categories: Personally Identifiable Information and Aggregate Information.

Personally Identifiable Information (“PII”)

This refers to information that lets us know specifically who you are. In general, you can visit our Site without telling us who you are or revealing any PII. As a visitor, you may voluntarily provide PII (such as name, address, e-mail address, and telephone number) to be shared with a Quarter-Max Affiliate for the purpose of contacting you, including via e-mail, to respond to your comments or inquiries. In such event, we might maintain a record of your contact, including such PII, in a file specific to you. We use this information to provide better service in the event that you contact us again.

Surveys and Promotional Activities

From time to time you may voluntarily provide PII to complete surveys and questionnaires or to participate in polls and personalized assessments. We use this information to improve our products and services. We may also use your PII to provide you newsletters and other marketing information we think would be of particular interest to you concerning things such as new product offers or web site features. But we always give you the opportunity to let us know if you do not wish to receive unsolicited promotional materials from us, and we will make every reasonable effort to honor such requests.

Aggregate Information

This refers to information that does not, by itself, identify you as a specific individual. Such information would include the Uniform Resource Locator ("URL") of the Web site that referred you to our Site, your Internet Protocol ("IP") address (a number automatically assigned to your computer whenever you surf the Web), your operating system and browser type, and any search terms that you enter on our Site. Our Web server aggregates this information to monitor the level of activity on our Site, evaluate its effectiveness, and improve the content of our Site to make your visit an easy and enjoyable experience.

We may collect, compile, store, publish, promote, report, or otherwise disclose or use any Aggregate Information, provided that such information does not personally identify you. We do not correlate any PII with the Aggregate Information that we collect on our Site. If we do correlate any Aggregate Information to you, it will be protected like any other PII under this Privacy Statement.
