    I purchased a corvette diffuser for $231. I was unable to use the screws provided as the pre drilled holes were too small. I couldnt drill them out as no nuts or instructions were provided. I contacted the business ***** times by text, phone and email. Mr. ******* claimed he had never had a defective one and refused to send a prepaid mailer for return and refund. He also indicated I would have to pay a 15% restocking fee. I checked reviews online and this sort of lack of customer support has occurred numerous other times. I am forced to pay the cost of return shipping a 15% restocking fee and can only hope I get a return. Any reviews I write will reflect this companys lack of customer support on defective products they sell and the difficulties I had getting any response from them.

    Buyer be ware!I was expecting so much more, but was I in for a treat! I truly hate to write negative reviews, but The short story is that EOS has issues to be concerned with. I would not recommend this company due to support and shipping are not in sync with each other. Good luck if you have damaged parts!The longer version is: I ordered the C7 stage 3 carbon fiber kit (kit is mixed with carbon flash and carbon fiber parts, ugh), grille, fender flares (carbon flash) and rear diffusers (hydro carbon). Their web page is very confusing as the same items are listed for both carbon flash and carbon fiber kits.Lets start with, a few parts were scratched badly (although, shipping box was not damaged). After contacting support at EOS, it was well over a week to get a response from them. I requested an RMA to return the damaged parts. I received the RMAs a few days later and it took over two weeks to get the replacement parts. The replacement parts came and another part damaged, three days for another RMA. Repeat return and shipping, 2 weeks.I also learned that the front splitter winglets and hardware was missing. I requested missing items. Regarding the damaged fender flare, I requested a refund. They sent me the fender flares again. The rear winglets mounting holes I found were too small in diameter and needed to be drilled larger. With the carbon fiber side skirts, each had s**** holes in wrong locations. A lot of engineering issues with these parts.When contacting support, they rarely answer the phone. Continue until you can leave a message, they state you should send email for a faster response. Dont worry, a text will follow for customer support. I left multiple messages and emails for each event. All of which were extremely frustrating due to the amount of time waiting for a response. It appears that support and shipping departments are not in touch and it takes days for them to communicate the issues. I would definitely NOT recommend this company!
