Frequently asked Questions

RRS Strut & Brake Kit view product

Q: How does the RRS conversion kit improve handling?
A. 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.

Q: Is RRS strut & brake kit better than original suspension set up?
A. RRS design is the only aftermarket product with a steering axis to suit modern radial tyres. 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.

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. Easy and simple to fit. 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. see video

Q: Will RRS strut kit help my steering?
A. YES - the original Ford steering geometry was designed for cross-ply tyres. No matter how good your tyres are they only hav3 a set amount of grip. The poor geometry on the original suspension waists some of this grip by having the tyres fight each other.

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

Q: I adjust height??
A.YES - there are two methods available to raise your vehicle up to 1-inch or lower it by as much as 3 ½ -inches

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

Q: What type of shocks do RRS use?
A. RRS use top range revalveable & rebuildable adjustable gas shocks with user friendly 4 point dial adjustable settings

Q: Do I have to cut my towers out?
A. NO - this is an optional procedure. 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! However you may well ask "is my Killer engine being strangled by poor exhaust"?

Q: Does cutting the towers cause stress on the chassis?
A. 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.

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 increase grip.

Q: Booster- Can I use my original booster if I change to RRS front strut & brake and RRS rear disc combination?
A. Yes however brake performance/pedal feel may be compromised by modified cams or heads. Gemini Booster & XA-XB disc/drum master cyl. Work very well on Mustang & KK to XP Falcon with 4WD. Light car - good proportioning rate.

Q: Is there any Warranty on RRS products?
A. YES - RRS quality products have a warranty of 12 months or 20,000 kms. RRS stand by products of their design and manufacture.

Q: Can I use my original steering with RRS strut & brake kits?
A. Yes RRS products will work in conjunction with your original Ford system.

RRS 3 link rear end view product

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: With the power kit, how does it feel at higher speeds?
A: RRS power rack provides steering and handling equivalent to XR8. Type of pump and pump pressure will also determine the feel at high speed.

Q: How much lighter is the new manual rack kit?
A: It weighs 18kg compared to the power RRS rack at 20kg

Q: What are the specs on the new Manual Rack Kit?
A: 4.33 turns lock-to-lock, equal to 16:1 steering box ratio.

Q: Is manual steering effort reduced over standard?
A: 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.

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.
