MOZA R3 to R12 & SRP pedals SimRig Mods

Some of these mods don't need to be downloaded with the details in description.  Its a collection of what I've got to work and found beneficial.

A collection of various mods and updates to a MOZA R9 Simrig with EX Wheel, SRP Pedals and TH8S Shifter on Next Level Racing Wheel Stand Lite 2.0.

In my order of effectiveness for performance and feedback:

• Brake springs and spacers
• Camming Clutch, great if you like stick.
• Pedal faces
• Phone Mount w Simhub
• 2 channel haptic feedback w Simhub
• Cable management.

Aim is to match feel and improve driving of as modelled in Assetto Corsa.

Updates:

• Haptic mount to SRP pedals.  Lot less harmonics than my first piece of timber and can act as guide to drill haptic mounts.
• Added less aggressive clutch profile
• Alternative cheap Haptic amp with input as USB sound card. Remember to change computer default, strange to hear YouTube come thru your pedals.

MOZA SRP and SRP-Lite Cam Clutch     

Adds higher spring force and camming action to match traditional Cluth.  The Profile and springs can easily be changed to adjust the feel. Action is similar to CRP pedals but adjustable via the changing the Cam plate and springs.  The Cam Plate is a simple slide in change. 

This has been working reliably and well for a couple of months.  Still it's a WIP so will update.  There is a spacer for the ramp allowing adjustment of the bite point.  The current Cam profile is pretty aggressive so will be trying a slightly less aggressive profile. It needed some mild double sided tape to stop it sliding forwards, I’ve added a less aggressive profile won't need the tape.  

Parts:

• 1 x Roller:  I used some https://www.amazon.com.au/dp/B09H2VF5HZ?ref=ppx_yo2ov_dt_b_fed_asin_title  608-2RS Ball Bearings Skateboard Bearings Double Rubber Sealed Shielded Miniature Deep Groove Bearings 8mm x 22mm x7mm for Skateboards Inline Skate Scooter Roller Blade Skates etc -10pcs I already had.  

• 6.3mm dia Steel/Alloy Rod, 6.3mm x 1m Aluminium Solid Rod - 6.3mm
• 4 x M3 Bolts
• Springs: Was going to use left over springs from Brake Kit which hadn't arrived.  Used Spacers to fit springs from Hardware Store and I think I prefer them, 14 x 34.9 x 1.8mm Compression Spring - 2 Pack. Can adjust with spacers to fit a variety of springs.

Instructions (To Do).  

• Designed that the walls (1.2mm min) provide the strength and reduce load.  Need something stiff rather than strong like PLA or ABS.  PETG is not so suitable as it will creep. 
• Majority Slots together pretty much as shown. The centre steel rod will need to be glued in.  A bit of grease from the 3d Printer on the rod is optional.
• Don't need to remove the original spring. Unless you want a super light.
• Parts are threaded for M3 bolts but can be drilled out and just use bolts as slip in dowels if printer doesn't form threads.  Minimum length 10mm.

MOZA SRP and SRP-Lite Brake Mods

Simple spring and spacer adjustments to improve feel of brake.

Parts:

• Springs:  Still waiting for Brake upgrade springs.
  Ordered green and yellow OD 20mm/ID10mm Die Springs Compression Mould Spring Light/Medium/Heavy Load Duty from Ebay.   

Green gave very heavy pedal similar to real pedal and more consistent than the rubber.  Prefer the Yellow gives a nice firm pedal with some extra movement giving better feel at limit.  Haptics ABS and wheel lock are also helping.  

MOZA Phone/Tablet mount for R3, R5, R9, R12.  

Adjustable low mounts down low for visibility through wheel.   Options for a Clamp using rubber band for tension and Logo insert in different colour.  

Profiled to base to avoid bending stress when bolted to Base.  Printing doesn't require much strength as stresses are low 

There is a file without the rear clamp that can be used on it's own with maybe some blutack to hold phone.  I'm finding the blutack in the lower jaws works quite well but I'm driving GT cars mostly.

Update: Haptic mount to SRP pedals.  Lot less harmonics than my first piece of timber and can act as guide to drill haptic mounts.

Printing

• It was printed vertical as shown which does need some support at base.  The support is minimal but needed to allow phone to sit low to be seen thru wheel.
• Was printed with 0.25 layer 0.4 nozzle PLA 3 walls 7% infill.

SRP and SRP Lite Haptic Motors.

Did these with some pretty cheap and simple components. No 3d printing used some timber offcuts instead.    Can easily generate some objectionable vibrations.   Need to turn down some effects.   Hardest part is setting up a decent SimHub Profile.

Parts:

• Bass Shakers: https://www.aliexpress.us/item/3256806517870372.html?spm=a2g0o.order_list.order_list_main.4.336518026HDDx2&gatewayAdapt=glo2usa4itemAdapt.
  
   

• Amplifier:  XY-AP50H HiFi Fever Amplifier Board Replaced above amplifier with this to give direct USB Soundcar connection to minimize lag(above is bluetooth).  https://www.amazon.com.au/dp/B0DJW759X5?ref=ppx_yo2ov_dt_b_fed_asin_title
• Used an old 19v laptop supply.

USB Hub and Power splitter:

To simplify packing away with just one USB Cable and Power Cable.
