    Rigid. Each kit includes a provision for solid mounting the motor in a way that greatly increases chassis stiffness, without using motor plates that are expensive to install; affording the serious enthusiast nearly the same rigidity as full motor plates, but can be installed without touching the engine, or even removing it from the car during installation. The rear plate is shaped to accommodate all known long tube header combinations

    Quiet Option: For the street driver that wants a sweet smooth street ride, or that has not installed a perfectly balanced flywheel and clutch, rubber mounting is available at no extra charge. Solid or Rubber mounting should be specified when ordering.

    Proven Performance: The geometry is nearly identical to that of the proven AIX National Championship winning GR40SLA systems already on the market, with the exception of minor changes due to track, wheelbase and CG differences between the ‘05s and earlier cars.

    Low: The inherent design of the S197 chassis allows us to make the car be very low in appearance; while maintain the well know “ Griggs Stance” as low as 2 ½ inches at the rear K member mounting plate. The resultant low center of gravity is FAST!

    Simple & Complete: The system replaces everything in the front end from steering to spindles to front cradle, along with the #1 cross member or radiator cowl support. Delivered from Ford this is a heavy part and a separate piece from the front cradle, but integral in the GR40 unit which weighs just 42 pounds complete. Since the integral design combines the two members, it no longer resembles a letter of the alphabet so we refer to it as the “Front Cradle”. Click to enlarge Click to enlarge

    Light weight, easy access: The complete GR40 system saves considerable weight as well, and makes working on the car a breeze. Using GR40 Alum spindles and Griggs 13.5” Sport Brake Kit, total OEM parts weight removed is 261 lbs. Total installed GR40 front end weight removes 30 pounds from the front of the car, most of which is un-sprung.

    Rear weight bias obtainable. Our test car yielded a 50.2 % rear weight bias full of fuel and with 210# driver, this was a GT in street trim, battery in stock location all systems stock except for the GR chassis and brakes. Other mods and/or track prep could move the weight back further. Click to enlarge Click to enlarge

    BIG TIRES FIT: The Unique GR40 SLA design allows us to fit under the stock sheet metal 285-18 tires on 10” rims, are standard Front and Rear. Larger sizes will fit.

    Easy Installation: All parts bolt on except for two small stiffener plates that need to be welded to the rear shock mounts on the rear axle. In the front, four 7/16” holes must be drilled to facilitate the installation.

    Incredible feel, input and response. The first impression of all drivers that have tested this chassis is the car drives and feels like it weighs half of its real weight. All SN197 GR40SLA cars require a steering rack change due to dimensional differences, and two racks are offered. Recommended for vehicles driven primarily on the street is the variable ratio unit with gearing as used on 03-04 Cobras. For those that demand quicker response, we also offer a very quick responding steering rack for those that want fast response and this is recommended for autocrossers, experienced road racers, and drifters. This system steers faster and more accurately than any GR40 system to date. We also supply a larger competition suitable steering fluid cooler with all the fittings and hoses to replace the extra long power steering hoses that are in the way of a clean installation, and to ensure long life of the PS system.

    You must supply your own SN95 (99-04) spindle and hub assemblies
