        What my 981 was missing! ( Verified Buyer )
        5 out of 5 stars.
        Brian Ritchie (Santa Clarita CA) | July 25th, 2025
        Night and day diff on how my 2015 981 S handles and sits. Do not hesitate getting this kit. The price for the performance and feel upgrade is a no brainer. Labor and alignment were an additional $2100. Mind blown that anyone would ever have built this car without this. Had to wait 7 months to get due to back order but well worth the wait. Suncoast are great to work with and kept me updated when I reached out for updates.
        Excellent upgrade
        5 out of 5 stars.

        The X73 Suspension Kit is an add-on / upgrade that every serious Porsche Boxster enthusiast should install on their cars! Improved / tighter / even more "in control" handling. Better grab around non-stop & go turns! Great appearance enhancement... lowers the car by 20 mm. The car truly looks impressive with its lower stance! And of course... as always... the Suncoast Parts customer support was great to work with! My mechanics moaned & groaned about the install... but that's what they get paid for! This was well worth it!!!
        Handling and driving experience is noticeably improved with X73 kit - 2014 Boxster 2.7 L

        I have invested in a lot of performance /power and appearance upgrades to my 2014 Boxster. I decided to buy in the OEM sport suspension to "complete the package." I was surprised how much better the driving/handling experience is now with the X73 suspension installed. The steering feels more direct, and the car more planted in turns; but, the ride is not rough for day-to-day driving. The gap around the wheels is reduced, as the X73 lowers the the car somewhat. This complements the look of my car which has 20" Carrera wheels, with spacers. It took a few weeks for Suncoast to find a the X73 kit to send to me. Overall, very happy with this mod. The kit completely replaces the stock standard suspension and the install is a big. So, you need someone with the requisite skills to make the parts swap. A local independent shop did mine
        Love the X73...'13 Boxster S

        Surprised nobody's rated this yet - awesome upgrade. Pros: Worth it. Excellent upgrade and transforms the cars' handling characteristics and slight improvement to steering feel. No ground clearance issues at all, scraping, etc. Looks much better than standard suspension...improved wheel-well look/ride height. Suncoast a pleasure to deal with - kept me updated on order status and shipping. Cons: A little rougher/stiffer ride on the street vs basic suspension. Back-ordered at Suncoast...took 4-5 months to arrive from ordering, since it was backordered in Germany and they had to send it to Suncoast. On my Boxster S, causes slightly more "rattling and creeping" inside the cabin from the rougher ride...but, worth it. Install and alignment cost an additional $1400-ish. Get it, you won't be disappointed.

        Understanding your warranty coverage is important. Below is a complete overview of warranty terms for Genuine Porsche OEM parts, aftermarket parts, and closeout items purchased from Suncoast Porsche and SuncoastParts.com.

        Warranty Coverage by Product Type

        Genuine Porsche OEM Parts — 2-Year Warranty

        All Genuine Porsche OEM parts purchased from Suncoast Porsche or SuncoastParts.com come with a 2-year, unlimited mileage, parts-only warranty beginning on the date of purchase.

        If your parts are installed at an authorized Porsche Service Center, both parts and labor warranty coverage may apply if the part is deemed defective within the 2-year warranty period. Coverage varies by location — please check with your local Porsche dealer prior to installation to confirm their specific warranty participation, as each Porsche Center is independently owned and operated.

        Important warranty notes for online purchases:

        • Labor, diagnostic, and installation fees are not covered when parts are purchased online from SuncoastParts.com or Suncoast Porsche, unless the parts are installed by an authorized Porsche Service Center
        • Warranty claims must be processed in person at an authorized Porsche Service Center
        • Warranty service is honored at any authorized Porsche dealer in the United States, however some dealers may decline warranty claims for parts purchased online or from another dealership — always verify with your local dealer before installation
        • If a warranty claim is approved and the part was not installed by a Porsche Service Center, installation of the replacement part remains the customer's responsibility
        • Suncoast Porsche and SuncoastParts.com are not liable for any diagnostic, labor, or installation fees charged by another Porsche Service Center

        Aftermarket & Performance Parts

        Warranty coverage for aftermarket and performance parts varies by manufacturer. Most carry a 1-year limited warranty. Contact us for specific warranty details on any aftermarket product. Please note that diagnostic time and labor costs for warranty replacements are not covered.

        Take-Off & Closeout Parts

        All take-off and closeout parts are sold as-is with no warranty and are not eligible for return. Pricing on these items reflects their as-is condition.

        The following situations and conditions are explicitly excluded from warranty coverage:

        • Improper Installation or Misuse — Damage resulting from incorrect installation, negligence, unauthorized alteration, or accident. This includes any use in racing, competition, or motorsport applications
        • Lack of Proper Maintenance — Damage caused by failure to follow the vehicle's recommended Maintenance Schedule, or failure to use the correct fluids, fuel, oil, or lubricants as specified in the Owner's Manual. Proof of proper maintenance is the owner's responsibility — retain all service receipts in case questions arise
        • Consequential or Economic Losses — Towing fees, rental vehicles, loss of use, loss of time, inconvenience, or any other indirect economic losses
        • Vehicles Outside the USA & Canada — Parts installed on vehicles registered or primarily operated outside of the United States or Canada are not covered under this warranty

        How to Obtain Warranty Service

        Installed by an Authorized Porsche Dealer

        If your parts were originally installed by an authorized Porsche dealer, warranty repairs may be performed by that same dealer or any other authorized Porsche Service Center in the United States. Please allow a reasonable timeframe for repairs after delivering your vehicle to the dealership.

        Installed by an Independent Repair Shop

        Please be aware: All warranty claims must be inspected, performed, and documented by factory-trained Porsche technicians at an authorized Porsche dealership. Work performed at an independent repair shop does not qualify for warranty consideration. If warranty coverage is a priority, we strongly recommend having your parts installed at an authorized Porsche Service Center.

        Documentation Requirements for Warranty Claims

        To process a warranty claim, the servicing Porsche dealer will require:

        • Your original sales receipt or order confirmation from SuncoastParts.com or Suncoast Porsche
        • A completed warranty certificate
        • Proof of proper vehicle maintenance history (if applicable)

        Suncoast Porsche retains sales records on file for two years. If you need a copy of your receipt, contact us and we will provide it promptly.
