RRS Strut and Brake Kits view product

Is RRS strut & brake kit better than original suspension set up?
A. YES - 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 material than standard rotors.

Q: How does the RRS conversion kit improve handling?
A.Because there are 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 - neg.camber (suspension droop) to + positive camber at maximum compression (bump stop).
- The RRS conversion kit gives a '0'camber at bottom stop (suspension droop) to 2 ¾ ° negative 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. see video

Q: Can I get replacement parts in case of accident or wear & tear?
A. Yes all standard replacement parts are available from main stream auto suppliers.

Q: What do I get in the strut & brake kit?
A. 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 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.

Q: How easy is it to fit?
A. Once the original Ford brake and suspension is removed the RRS conversion kit bolts in place needing no welding, fabrication or additional parts to be purchased.
No special tools are required to fit the RRS conversion kit. If the fitter follows our detailed instructions, the vehicle being converted can be back on the road in less than 6 hours, providing that all of the original brakes, lower arm and chassis are in good working order. No welding or cutting. see video

Q: Will RRS strut kit help my steering?
A. 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 waste some of this grip by having the tyres fight each other. The advantage of an RRS strut over double wishbone is faster reaction time and decreased chassis stress. The double wishbone is good only if the arms are longer, chassis does not permit this.

Q: Can I use my original steering with the RRS strut & brake kit?
A. Yes you can use your original steering, RRS products will work in conjunction with your original systems. There are some variations with 65/66 Mustang and 60/66 Ford Falcons so please check with RRS.

Q: Can I adjust my height?
A.YES - the RRS strut leg is designed and threaded to turn down into itself enabling vehicle as much as 3 ½" of adjustment. There is also adjustment for spring tension by adjusting spring retainer lock rings.

Q: Does the RRS strut alter vehicle height?
A. 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.

Q: Is it lighter than original suspension?
A. the Strut assembly decreases un-sprung weight by approximately 3kg. (6.61 lbs)

Q: What type of shocks do RRS use?
A.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
- Different shocks can be supplied to suit different driving requirements e.g. drag racing 90/10, touring gas shocks, competition adjustable shocks (NB: custom shocks are priced on application)
- Replacement shocks can be purchased at most hi-performance suspension parts suppliers.

Q: What about the springs?
A. 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

Q: Do I have to cut my towers out?
A. NO - it is not necessary to notch your towers to fit RRS coil over strut system. 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"?

Q: Does the RRS conversion kit change chassis stress?
A. A. 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.

Q: When an RRS kit is fitted, because the chassis is less stressed, what benefits can be expected ?
A. 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.

Q: How does the RRS strut conversion effect steering geometry?
A. 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.

Q: Can I adjust camber?
A. 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.

Q: Will this change the roll centre?
A. NO - the vehicle will be stable in high speed corners with increased grip.

Q: Booster- Can I use my original booster if I change to RRS front strut & brake and RRS rear disc combination?
A. Yes you can use your original booster, however brake performance/pedal feel may be compromised by modified cams or heads. All RRS brake kits produce balanced combinations.

RRS also have an under-dash booster/master cylinder kit. view now

Q: Can caster adjustment be made to RRS struts?
A. 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.

Q: What type of wheels can be fitted to the RRS strut and brake kit?
A. 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. view more info on this now

Q: What Exhaust clearance issues need to be considered?
A. All brands of headers will fit, factory H pipes will fit, x pipes will have to be custom made to fit and tail pipes will require some modification to fit or be custom made

Q: What about Ground Clearance?
A: From a side view no 3 link components are visible, the lowest components underneath the vehicle are original exhaust and chassis members.
From the rear, the coil over mounts are visible and providing the vehicle is fitted with OE diameter tyres or larger (ER7514). approved ground clearance is maintained.
RRS 3 link is height adjustable with full bump position the same as OE

Q: What about Pinion Angle
A: Pinion angle is determined by RRS tooling and is guaranteed to be correct for all factory fitted gearbox and differential combinations.
For custom differential and gearbox combinations RRS can provide offset differential mounting pad dowels and or an eccentric torque arm bolt locater.

Q: Where do I get Replacement Parts
A: RRS has used Ford OE Size Bushings made from urethane; therefore OE bushings can be sourced or alternatively replacement RRS bushings can be purchased from any RRS distributor. All links and mounting hardware is unique to RRS distribution outlets

Q: How do I install this booster kit?
A: You simply unbolt the pedal assy. and booster and master cylinder and bolt the new RRS booster /master in its place, using the same bolt holes mount the fluid reservoir in the engine bay, hook up the reservoir lines and the only two things that have to be fabricated is the front and rear brake lines, clutch hydraulic line and brake switch.

Q: Do I need to do anything to the firewall before I paint it?
A: You will be putting a mounting bracket on the firewall.

Q: What performance increase over standard disk brake 67 stang with Phase Two package?
A: OEM stopping distance at 100km / hr is reduced by 6m with RRS Phase 2 brakes. Also, repeated braking permance without fade for up to 10 repeated stops. Standard brakes will fade after 2 repeated stops.
