Customer reviews

From the people running the parts.

Real Apex customers, real builds. Full reviews live on Google, Trustpilot, and the brand sites we sell.

★★★★★
Ordered a Brembo BBK on Thursday at 3:55pm — tracking number by 4:30, on my porch in Austin Saturday morning. Tech rang me before they boxed it to confirm caliper color. That's a level of care I haven't seen from the big sites.
★★★★★
Their fitment team caught that the coilovers I ordered were the AWD spec when I have RWD — before they shipped. Saved me a return, a re-order, and a weekend. Apex is the only place I'll trust with suspension now.
★★★★★
Phone support is ASE-certified guys who actually wrench on the weekends. Asked them about pad selection for a track day; got a 10-min breakdown on bite vs. fade, no upsell. Bought the cheaper compound they recommended.

Frequently asked

What customers ask before they buy.

What does your fitment guarantee cover?
If a part we ship you doesn't fit your year / make / model / trim, we cover the return shipping and either source the right one or refund in full — for 30 days from delivery. We try to catch fitment errors before they ship by having an ASE tech review every order over $250.
How do returns work?
30 days from delivery for new, uninstalled parts in original packaging. Free return shipping for fitment errors on our side; flat $9.95 prepaid label for change-of-mind. Refunds posted within 48 hours of warehouse receipt. Custom-tuned ECU and bent-to-fit exhaust are non-returnable once shipped.
Which states do you ship to and how fast?
All 50 states + APO/FPO. Lower 48: standard ground is 1-4 business days from our Charlotte NC warehouse, free over $99. Express overnight + 2-day available at checkout. Alaska, Hawaii, and PR: flat-rate freight, 3-7 business days.
Are you an authorized dealer for these brands?
Yes — we're authorized for every brand listed on our site. That means manufacturer warranty support, no gray-market parts, and direct factory tech access. We don't drop-ship from sketchy distributors. If a brand isn't authorized, we won't carry it.
Do you offer install support?
We don't install in-house, but every order ships with the manufacturer's torque specs + a QR link to install videos on our YouTube channel. Phone tech support (ASE-certified) is free for any part you buy from us, lifetime — (704) 555-0177 Mon-Sat 9am-8pm EST.
Do you ship internationally?
Canada, Mexico, EU, AU, UK via DHL Express. Duties and taxes calculated at checkout (DDP). Some emissions and DOT-restricted parts cannot ship outside the US — we flag those at checkout before charging.
What happens if a part is on backorder?
We show real warehouse stock in real time. If a part goes on backorder after you place the order (rare, but happens with limited drops), we email within 4 hours with the ETA and your options: hold, swap for an in-stock equivalent, or full refund — no questions.
Do you take Apple Pay / Google Pay / financing?
Visa, Mastercard, Amex, Discover, Apple Pay, Google Pay, Shop Pay, PayPal, and Affirm financing (3-, 6-, or 12-month plans, 0% APR on most orders over $300). ACH and wire for orders over $5,000 with 1% off as a thank-you.
