Good products at this website. Great Customer Service! Awesome and quick shipping. You've got a repeat Customer!!

Great communication, fast shipping. I haven't dealt with any issues using the K5 Optima Store.

I experienced and continue to experience great service and products from this company and I'm pleased to be a customer.

Dave is always great with helping and going the extra miles to get you what you need. Awesome products and above and beyond customer service! Always a pleasure!

I had one issue on my first but but, was taken care of with no problems. No issues with my other purchases. Great place for my Kia.

Ordered a few things from here, ships literally within minutes every time I've ordered or at least on the same day so it can get shipped out fast. Super fast/friendly customer service too, and amazing product, well worth the price:sign_horns:

Great service. As always. Bought the red T for the front grill. To make my car just a little different. Thanks again

Shipping didn’t take long, arrived in perfect condition supper easy to install

Ordered Road Run grille was delivered promptly and was as nice as advertised

Good Product 👍

Really impressed with K5 Optima .Quality product , simple instructions for our Australian Hyundai Kona seat lift fittings . Would thoroughly recommend them to all .

Nice and simple site, not complicated at all to find the items needed.

Had some difficulties aligning the bolts, but once I did the rest was a piece of cake. Makes a big difference in the passenger ride height. Don't know what Kia/Hyundai was thinking when they decided not to offer passenger ride height adjustments for most of their 2011-2016 line up. This kit is definitely worth the purchase. Thanks for a great product!
