FAQs

RRS design is the only aftermarket product with a steering axis to suit modern radial tyres.

YES RRS strut provides a vastly superior steering geometry and ride control & ride quality with faster reaction time and decreased chassis stress with 100% improvement on handling and accurate response.

RRS brake kits are lighter stop faster over distance and are made from a stronger molycarbide material than standard rotors.

Because there is less moving parts than the original Ford front suspension, less deflection occurs and therefore:

• The handling is more accurate and responsive.
• The original Ford suspension inherently has a camber shift from -camber (suspension droop) to +camber at maximum compression (bump stop).
• The RRS conversion kit gives a '0'camber at bottom stop (suspension droop) to 2  ¾ ° camber at maximum compression (bump stop).
• RRS set up produces a lower roll centre while creating a jacking effect to reduce body roll
• This all adds up to more even and full 'tyre to road' contact in hard cornering and increased stability.
• The RRS conversion strut assembly decreases un-sprung weight by approximately 3kg.
• Improved suspension reaction resulting from modern superior spring wire and shock absorber design.

Yes all standard replacement parts are available from main stream auto suppliers.

You receive a full Strut assy. complete with strut leg, top hat, springs, shock absorber, Knuckle/spindle (which replaces the original stub axle), forged alloy steel hub with 20% increase load bearing and all attaching hardware & spanner PLUS detailed installation instructions

Plus brake package or your choice– including rotors, callipers & brake lines.

Easy and simple to fit.  Unbolt and remove the original suspension system, including the upper control arm and simply bolt in

pre-assembled strut leg assy. into top of shock tower, connect brake package.  No special tools required.  No welding or cutting.

YES – the original Ford steering geometry was designed for cross-ply tyres.  Modern radial typres have a lower angle of deflection therefore the poor geometry on the original suspension waists some of this grip by having the tyres fight each other.

Yes you can use your original Ford steering, RRS products will work in conjunction with your original systems.  There some variations with 65/66 Mustang and 60/66 Ford.

YES – the RRS strut leg is designed and threaded to turn down into itself enabling vehicle as much as 3 ½  –inches adjustment.  There is also adjustment available in adjusting spacers below the springs to suit spring tension.

The strut assembly is fitted with a collar and lock-nut assembly that can adjust ride height with 3 ½” of range.

Standard ride height is maintained with the maximum “up” setting or be lowered 2 ½” on the maximum down setting while maintaining legal bump stop and spring pre-load settings.

YES – the Strut assembly decreases un-sprung weight by approximately 3kg. (6.61 lbs)

RRS use top range adjustable gas shocks with user friendly 4 point dial adjustable settings.

AGX adjustable Gas Shocks:

• Adjustable damping allows AGX shocks to be dialled in to match driving conditions
• A single adjustments changes rebound and compression settings to go from track, to high speed touring to street cruising in seconds
• Fast on-car adjustment no need to lift the vehicle to remove shock to change settings
• Sintered iron piston and guide rod for greater strength and durability
• Micro smooth, hard chromed piston rod for long- life reliability of oil seals
• Seamless cylinder and eye rings mean no weak points, no seam failures
• Multi-lip seals and self-sealing packing keep oil in, contaminants  out, even under repeated hard use
• Patented check valve minimizes foaming, keeps shock performance fade-free

• All RRS springs are manufactured using the highest quality chrome silicon wire
• This material offers high strength, consistency and longer life
• RRS springs are powder coated blue for excellent longevity.  All RRS springs are lifetime guarantee to remain with 5% of original free height under normal operating conditions

NO – this is an OPTIONAL procedure and is available to gain up to 11” more space in the engine bay for hi-port heads, big block or just to reach the spark plugs!  You may well ask “is my Killer engine being strangled by poor exhaust”?

NO in fact there is less stress – RRS strut mounting eliminates 100% of stress exerted on the middle of the tower caused by original Ford system.  The vehicle weight is primarily carried by spring and shock location within the strut leg.

The strut mounting eliminates 100% of the stress exerted on the middle of the original Ford shock tower by the standard upper-arm, which operates as a lever on the original spring and shock absorber.

As much as 50% less stress at the spring seat.

The vehicle weight is primarily carried by the shock-tower spring location.

When an RRS strut kit is bolted in place, the chassis is less stressed than original Ford suspension set-ups.

Convertible scuttle shudder is easily eliminated with the RRS conversion kit

A more responsive shock and spring operation, rather than chassis deflection (flex).

Because the chassis has reduced stress by fitting an RRS conversion kit, (which also eliminates the Ford upper-arm) the shock tower can be cut away and plated, (by a qualified repairer) to allow 5” to 6” of additional cylinder head clearance to each side of the engine.  This makes it easier to fit hi-port heads, more efficient extractors, big block engines plus easier access for turbo installations.

Custom wheel alignment settings are provided for each “individual application” to reduce “factory bump steer” and improve “track on turns” by custom “Ackerman angles”.

Any competent wheel alignment shop can adjust and set the wheel alignment according to our specifications to provide maximum road holding and minimize wear characteristics.

A camber pin lockout can be fitted to eliminate the troublesome habit of some Ford’s slipping out of alignment.  Camber can then be adjusted by a positive stop, non-slip camber adjustment on the RRS manufactured steering knuckle.

Tech Article – Roll Centre

Body Roll and force distribution camber control

The amount of body roll is called the roll angle.  This is determined by Roll stiffness the relationship of Roll Centre and centre of gravity.

Centre of gravity lowered reduces body roll, however if the distance between the roll centre and the centre of gravity is to wide body roll will increase

High roll centres will result in jacking effects and erratic handling.

Understeer oversteer characteristics

Scrub radius is improved - the amount of movement the tyre makes across the road (sometimes equated with track variation) as the suspension moves through its travel.

Steering angle deflection, oversteer And understeer characteristics and a “twitchy” road feel at speed are eliminated by the RRS design

Torque steer resulting from deflection and geometric angles causing a typical roll oversteer is also eliminated.

YES and with far more range – it is easy to reach and adjust camber if required with a ring spanner to maintain a full tyre to road contact in hard cornering

NO – the vehicle will be stable in high speed corners with increase grip.

Yes, however brake performance/pedal feel may be compromised by modified cams or heads.  All RRS brake kits produce balanced combinations.

YES – RRS quality products have a warranty of 12 months or 20,000 kms.  RRS stand by our products of their design and manufacture.

Yes you can adjust the caster.  The standard caster bar at the front or fit an RRS adjustable castor rod.

RRS use typically around, depending on vehicle application,  13 ½  ° steering axis inclination that is correct for modern radial tyres and is far less effected by minor castor errors than the factory 7 ½ steering axis inclination that is common to all early Ford designs from 1960 through to 1987.

Standard Ford stud pattern and wheel track means that all standard 14” 1974 on model wheels can be used along with after-market 14” to 17” diameter rims, and will suit original 14” rims and larger.

Wheel width can be altered from Ford’s standard 4 ½” inward offset to 5” inward offset.  The wheel hubs are fitted with standard Ford ½ “ UNF wheel studs.

RRS precision steering provides better handling, quick response and is more direct. The unit is re-buildable and serviceable.

RRS power rack provides steering and handling equivalent to a 2010 XR8. The Type of pump and pump pressure you use will also determine this feel at high speed. RRS pump kit also available.

RRS Manual 6.6kg.lighter and RRS Power 4.2 kg lighter than original system

RRS Constant mesh Rack & Pinion steering unit power/manual with linear tracking system, 1 pr. outer tie rod ends, Brackets to hold RRS rack, which anchor in stock position, Internal column conversion kit - internal shaft section and universal joints.

No modification required. Simply remove the original worm & sector style steering, Remove steering box, Remove Idler Arm, Remove drag link, RRS brackets bolt into the original steering box & idler arm holes.

No - the RRS rack mounts behind the front cross member. This mounting location is essential and RRS installation instructions must be followed.

No - the RRS rack is mounted 8-12mm higher that original steering. Spacers can be used to lift engine block by 6mm

No - the RRS rack will work with the original Ford pump system.

Yes - you can use an alternative pump to original. RRS have a pump kit available directly into your original pump bracket or can be modified to fit onto engine.

800 up to 1600 psi RRS never recommend running over 1200 psi. 850 psi is good. RRS pump has lower pumping pressure and flow volume Flow rate at idle 1 ¼ to 1 ½ gallons a minute 800 up to 1600 psi RRS pump has a lower pumping pressure and flow volume.

Yes - RRS rack system mounts into stock position and complies completely with Australian light vehicle requirements. Some states do not require approval.

The RRS rack reduces the number steering wheel revolutions from 4.25 turns atypical to 2.88 turns lock to lock. Typical Ford leverage ratio XW 16:1 = RRS 12.8:1 All RRS racks are fast ratio, constant mesh design. RRS racks match original turning radius when using RRS strut kits. Depending upon the spindle combination the Ford OEM suspension systems may reduce the turning radius by up to 3 ft. (1 metre).

RRS rack systems provide a large amount of additional clearance to allow easier access and installation of most aftermarket header systems (some long tube header designs eg. Hooker long tube to suit 1969 Mustang big port Cleveland has one pipe that fouls the RRS rack power head). All Shorty headers will easily clear RRS rack installations. All mainstream brand TriY's headers will clear RRS rack installations. Clearance will depend on the application of headers and engine you choose.

Advance headers tri y configuration is recommended for early Mustang. Pacemaker 4 into one header will require one pipe modified on drivers side.

It is best to leave 25mm space and a heat shield. For Cooling -using a heat reducer will help if the header is too close.

YES - RRS supply an internal shaft conversion kit which comes complete with universals to bolt directly from rack through your steering column to steering wheel.

No.

YES - however it is essential that client provide RRS with the column details so correct inner conversion shaft is provided.

NO - bump steer is not increased indeed if you also install RRS coil over suspension system RRS will guarantee you can reduce bump steer to zero.

No other parts are necessary. All hardware is supplied with the RRS rack kit. Pump and hoses are not included in the Rack kit and are available separately.

NO unless the car is stationery and engine switched off Because the power system works on rotary valve (cylinder around another cylinder) check the following;

1: make sure tie rod ends are tight

2: make sure the steering wheel is tight on spline

3: if uni joint set screw is loose you will end up with free play

NO - RRS provide new wheel alignment guidelines with the installation instructions. The alignment will be like late vehicle alignment.

4.33 turns lock to lock, equal to 16:1 steering box ratio.

The effort required with the RRS manual rack system is comparable to quick ratio OEM manual 16:1 steering ratio. However because of the racks constant mesh design there is no free play just off centre like OEM systems.

RRS Guarantee and Warranty: RRS products have undergone rigorous engineering analysis and testing by some of the World's toughest Government authorities and engineering signatories, which enables RRS to standby it's products as if you buying an OE replacement part for your road vehicle. No other steering system meets RRS high standards.
