All international orders must be prepaid before shipment can be sent. Due to the constant fluctuation of currency rates and depending on the items being ordered, your freight fees will vary. It is important that you contact SR1 Performance for shipping quotes. Shipments outside of the Continental US may incur customs fees, Duties, or Taxes depending on the destination country.

CORE CHARGES
Our exchange program is very simple and allows you to receive chrome plated wheels or powder coated calipers without unnecessary down time to your vehicle. We first send you a set of our high quality chrome plated GM wheels or powder coated calipers to have installed. The best way to purchase is with a credit card. We initially charge you for the Chrome Plating
(wheels) or powder coating (calipers) plus a refundable core charge.
You must return your undamaged cores within ten (10) days, we then issue you a full core credit within ten (10) days of receiving the product. Cores returned late (after the 10-day period) will be charged a $30.00 (per day) late fee. There will be a $100.00 stripping fee on painted caliper cores. To insure the highest quality available we only exchange GM products and they must be for the same style and year. Any damages will be deducted from the core refund. You may contact SR1 Performance for return shipping assistance.
WARRANTIES
All items are warranted to be free from defects in materials and workmanship at the time of shipment to you. Your purchase will be backed by the limited warranty extended by the manufacturer of the parts. SR1 Performance and the manufacturer will not honor warranty requests due to shipping damage, improper handling or installation, neglect, accidents, or competition use. Warranty claims apply to parts only. All Chrome Exchange wheels come with a 3-Year Written Warranty. Our 1-piece reproduction wheels come with a “Lifetime Limited” structure and a 2 year chrome warranty. All wheels should be checked for trueness or run-out before installation, in case shipping damage has occurred. All wheels should be test fit before installation to assure proper clearance of brake rotor, brake caliper, inner and out fender and brake cooling duct. Complete warranty will accompany wheel shipments. SR1 Performance does not directly warrant any high performance part or labor. Performance parts are installed at the customers risk and any warranty claim must be taken up with the manufactures. Performance parts may or may not meet individual state emission laws.

All SR1 Performance Forged Wheels are designed for street use only. Warranty is void if used for racing.
