Griggs Racing Front Suspension Systems @ Last Call Racing

GR40 Street Performance The Griggs Racing

Mustang_Kit

starter system includes the foundation to make a street-driven Mustang into a smooth riding Porsche killer. This kit was configured to give you incredible hookup and cornering performance. This system focus on the weakest link in the S197 platform the front suspension. This is the best place to start on your S197 Mustang and will give you a great foundation for future upgrades. Major components include Coil-Over Front Struts, urethane bushings and the GR40ST Rear Suspension. Installation is as easy as it gets with no welding required. Whether you drive your Mustang to work or in the canyons this kit is guaranteed to yield significant performance improvements.

Includes: Single adjustable, custom valved Konis in short coil-over strut housings, springs and camber/caster plates

Complete Shortened Front Strut Housing Machined from seamless DOM 1026 steel alloy tubing. Heavy-duty sway bar bracket welded on. The design is much stronger and more rigid than any of the aftermarket housings that are actually modified stock housings, with skip-welded gussets and and all original brake line and abs tabs retained.

Koni Single Adjustable Front Strut Struts are externally adjustable from underneath the hood, even with the factory strut brace. This strut is prepared for coil over use, and eliminates machining of critical suspension components.

Threaded Sleeves. This system is designed to eliminate stress risers caused by machining notches into the strut housing.

Adjustable Spring Perch A unique design, which uses an Allen head bolt to clamp the single threaded perch into the correct position. No secondary pieces are needed to "jam" the threaded perch into position.

1 Pair front Camber Plates

Camber / Caster Plates Correct camber adjustment at the top of the strut. Caster adjustment, aircraft bearings, engraved with calibrated degrees. Every component is anodized or plated, including fasteners. Adds extra travel to avoid excessive bottoming out, this is a very well engineered product.

Camber and caster are adjustable by sliding the mounts, without removing any components from the car. The priority of this design is to allow repeatable alignment changes which the S197 Mustang needs.

The camber plates feature a bearing and a bushing, which allows for articulation of the shock shaft. The steering bearing is very under stressed, as the design does NOT articulate the steering bearing.

4 springs, manufactured by Eibach, to custom specs Eibach springs are made on German machines both in the USA and in Germany, however all Eibach springs have a lifetime guarantee against sagging, rate change, or any manufacturing or material failure. Lifetime guarantee. Compare.

2 bump stops (made in Germany)

We do not just ask you to reuse your stock bump stop. The stock bump stop is designed for stock suspension we provide a bump stop designed to work with the suspension. These are soft foam, same quality as OE Ford parts, but made to custom specs in Germany.

* Suspension is shipped completely assembled and preadjusted*

 


S S197PF

GR40ST Ultimate Street Performance

The first of the Griggs Racing S197 SLA systems, includes the foundation to make a street-driven Mustang into a smooth riding Porsche killer. This kit was configured to give you incredible hookup and cornering performance. This system focus on the weakest link in the S197 platform the front suspension. Significant weight will be shed from the front end and give you a great foundation for future upgrades. Major components include a Tubular Front Cradle, Koni Coil-Overs and an SLA System. Installation is as easy as it gets with no welding required. Whether you drive your Mustang at the strip or in the twisties this kit is guaranteed to yield significant performance improvements. This is our most popular SLA system.

Includes: Single adjustable, custom valved Konis in short coil-over strut housings, springs and camber/caster plates

Complete Shortened Front Strut Housing Machined from seamless DOM 1026 steel alloy tubing. Heavy-duty sway bar bracket welded on. The design is much stronger and more rigid than any of the aftermarket housings that are actually modified stock housings, with skip-welded gussets and and all original brake line and abs tabs retained.

Kit Contents

  • Tubular Front Cradle
  • SLA Tower Set
  • Bump Steer Kit
  • GR40 Lower Street Steering Shaft
  • Steering Rack Set
  • SLA Tubular Front Lower Control Arms
  • Urethane Lower Control Arm Bushings
  • SLA Street Front Upper Control Arms
  • Ball Joints
  • Upper Ball Joint Adapter
  • Koni SLA Street Coil Over Kit
  • Anti-Roll Bar Kit Zero Bind

    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 ˝ 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
