AMT Ultra-Low Seat Mount For Corvette C5 Through C8 Sub Strap Mount Included The Best Way to Put Proper Seats in Your Corvette Throughout the years, the iconic Corvette has been equipped from the factory with many great features. Unfortunately, the seats aren't one of them. Those Corvette drivers who have added a proper racing seat to their Corvette often say it's the most important mod they've made to increase their track-day enjoyment and safety. However, a proper racing seat should be mounted from the side on fixed mounts, not using the OEM seat hardware. As a result, headroom becomes a concern with any racing seat in a Corvette, but AMT Motorsports has effectively eliminated that concern with the Ultra-Low Seat Mount. The Benefit of Innovative Design Countless development hours were spent making the Ultra-Low Seat Mount the best available for the Corvette. (The only way to get your seat lower in your car is to cut a hole in it!) The bottom of the seat can literally touch the floor in your Corvette. By machining a perfect hex in the mounts to accept the mounting bolts for the side brackets, AMT maximizes seat clearance. This machined hex also removes an extra wrench (and a whole lot of headache) from the install process. These seat mounts are machined from 6061-T6 extruded aluminum. Rather than allow the side brackets to only sit on bolts, AMT machines the brackets so there's a perfect mechanical interface with the bottom and side of each floor mount, increasing stiffness and strength. Included with every mount are studs and hardware to allow the mount to be bolted using the factory Corvette seat studs. Sub Strap Bar Included Finally, there's a movable cross bar to accept five- and six-point sub straps. This sub-strap bar is bolted to the floor mounts with flat head screws, and there are two more holes in the cross bar in case your sanctioning body requires you to bolt the bar through the floor. Two eye-bolts are included with the cross bar. We don't recommend using a different sub-strap bar with the AMT mount since you'll need to modify either the mount or the sub-strap bar to get it to fit. Lifetime Guaranteed Quality As with everything AMT makes, these mounts and sub-strap bars are proudly 100% made in the USA. If any part of the mount fails for any reason, AMT Motorsport will replace the offending part free of charge.

Brey Krause C6/C7 Corvette Extra Low Seat Mount w/ Sub-Bar The Brey Krause R-9153 Driver-side seat mount offers a solution to the low roof-line of the C7 Chevrolet Corvette. The racing seat adapter places the seat rails at a slant, allowing the seat to be lower in a rearward position when combined with a Recaro Slider (sold separately). This slant allows the seat to sit higher when in a forward position (perfect for shorter drivers), while offering increased head clearance when adjusted rearward for taller drivers. The R-9153 bolts directly to the floor of the C7 Corvette, and combines with a Recaro slider to allow the installation of many seat options when used with Brey Krause side-mounts. Also compatible with the C6 Corvette if you are searching for additional head-room.The mounting kit comes complete with an adjustable integrated Sub-Bar for correct mounting of your 5 or 6 point harness system. The design also allows for the reuse of stock 3-point belts, with inboard/outboard lap belt mounting locations built in. Note: Brey Krause Seat brackets must be purchased separately - see Brey Krause R-906X series side mount brackets.PLEASE NOTE: Although this kit allows for the installation of many brands and models of seats, due to the extremely low roof-line and the tight confines of the C7 Corvette, many larger seats will not fit. Please contact one of our racing seat experts (844) 438-7244 with questions relating to your particular installation needs. FEATURES: Materials: Aircraft-grade aluminum and Type 304 stainless steel (sub-bar) Finish: Black gloss powder coat Weight: 7.8 lbs.
