HO2 Coil-Over Front Suspension

Challenge the road with improved suspension performance

The RRS strut kit comes with your choice of RRS upgrade brake packages ranging from single-piston to huge 6-piston calliper kits. All mounting hardware is included and is easily installed without the need to cut or weld your precious classic Ford.

The RRS coil-overs are bolt-in. The coil-over system easily bolts into classic Ford Falcon, Fairlane, Mustang, Cougar, Comet, Maverick, Cyclone, Montego, and Torino.

Building a daily, a cruiser, or a racer, you want it to outperform all other classics, stock or modified. The RRS coil-overs improve the castor and Ackerman to respond faster, creating a jacking effect, which will optimise the suspension performance.

In-Depth RRS Front Coil-Over Suspension Benefits

• RRS is the only suspension system on the market today that is designed to extract the maximum performance out of today's advanced tyre compounds and construction.
• In comparison the original Ford suspension inherently has a camber shift from negative camber to positive camber at bump stop. While the RRS system gives a optimum 0° camber to 2 ¼ ° negative camber at maximum compression or more.
• The RRS system produces a lower roll centre while creating a jacking effect to reduce body roll enabling the suspension to utilize a lighter sway bar.
• The advantage of the RRS system is that it produces full tyre to road contact in hard cornering and increased stability while decreasing unsprung weight by 3 to 5 kg per side producing quicker suspension reaction time due to the superior spring and shock absorber design.
• Inferior competitor designs such as Mustang II continue to use lower control arm mounted coil over and converted struts which are basically a tweaked version of the original 1960's Ford design that was developed to suit cross-ply tyres or worse will cause incorrect chassis loading and mismatched components.
• RRS modular design strut conversion uses a bearing hub rather than a stub axle providing the most advanced steering geometry, ride control (reaction time) durability and serviceability in the market.
• The RRS forged steel hub increases the load bearing capacity by 20% over the original factory stub axle. Perfect for wide big diameter rims & tyres.
• The RRS adjustable gas shock features a patented check valve which minimizes foaming to keep shock performance fade free under all driving conditions.
• Retains standard Ford stud pattern and stud size & wheel track.
• RRS discs have a different offset to a standard Ford to allow bigger rotors within standard rims while maintaining factory wheel track width.
• Caliper mounting is designed to allow a greater adaptive design range and ease of fitment of high performance RRS calipers.
• RRS detailed instructions make installation a breeze.
• Lightweight-less weight on the nose means better weight transfer and proven, better 60 foot times at the drags.
• Reduces track scrub, a typical early Mustang or Falcon with standard suspension will vary track by up to 3" through its range of travel . The RRS strut decreases this to less than ½".

Torque Specification for RRS Front End

1. Wheel nuts 100 – 125nm
2. Tie rod ends and ball joint 40 – 60nm
3. Steering knuckle to Strut tube, attaching bolts in two stages:
4. Stage 1 = 85nm
5. Stage 2 = 100nm
6. Front calliper to the steering knuckle, attaching bolts 80 – 90nm plus 40° – 50°
7. Wheel bearing hub to the steering knuckle, attaching bolts. This is done in three stages:
8. Stage 1 = 85nm
9. Stage 2 = 100nm
10. Stage 3 = 100nm then turn through 90°
11. Top hat attaching bolts 35nm
12. Strut insert, attaching nut 125nm
    

Recommended wheel alignment specifications for your Ford:

• Caster positive 4.5° plus or minus 1°
• Camber negative .5° to negative .75°
• Toe in 2mm to 3mm
• Toe out on turns
• Outer 17.75°
• Inner 20°

These are general guideline recommendations and therefore should be considered as a starting point to allow fine-tuning to suit specific requirements. For further advice please contact RRS directly on +61 2 9907 3755.
