H-Paddle Shifter Kit - MME Motorsport

H-Paddle Shifter Kit

Revolutionary H pattern gearbox to paddle shifter kit

Sequential only paddle shifters are history!

MME Motorsport H-Paddle Shifter Kit contains everything you need to run a fully pneumatic paddle shifter on your regular H gearbox. By using auto clutch option it supports synchronized gearbox too.

Kits starting from 3500 EUR + VAT

What’s the benefit of our paddle shifting system over manual shifting?

  1. You can convert any H gearbox to paddle shifter which was previously only available to (expensive) sequential gearboxes
  2. It’s just faster. At least one time faster than any shifting with hand
  3. You can concentrate purely on the road
  4. You can safely shift in fast long corners (with both hands on the steering wheel)
  5. We protect your engine by not allowing the driver to over-rev the engine with incorrect downshift
  6. We reduce gear wear by performing clean, fast & reliable shifts
  7. You can up-shift with full throttle without the clutch
  1. You can down-shift without the clutch*
  2. You can pre-select any gear at full throttle on a straight line (say in 6th gear) and when you start to brake, gearbox will automatically down-shift down to your pre-selected gear at perfect engine rpm. The harder you brake, the faster it will down-shift
  3. Because you don't need the clutch, you can easily use left foot for braking to stabilize the car and gain speed over the corners
  4. You can use launch mode and as long as you're at full throttle, the gearbox will shift automatically at perfect rpm so you get perfect starts every time
  5. If you already have engine control unit capable of shifting sequential gearboxes you can let your ECU do the shifting. System will just receive the shift command and perform the shifting sequence.
* We offer optional clutch kit which means our system will also automatically press & release clutch when down and/or up shift (even on synchronized gearboxes). See kit content.

Frequently asked questions

  1. Can I use this on Synchromesh gearbox?
    Yes. It is possible to use our system if you have hydraulic clutch. What we do is we supply additional actuator and hydraulic actuator that presses and releases the clutch automatically. 
  2. What is needed to install this into my car?
    - Gear lever must be replaced by the h-paddle shifter assembly. Usually the cables need to be shortened to properly fit. Cables on the actuators side need M6 male thread. We supply these cables at extra cost.
    - Air compressor and air reservoir must be mounted and connected to power and gear control unit
    - Gear control unit must be wired according to diagram. Basically you need 12V from ignition switch, ground, paddle up/down switches, clutch switch and neutral switch. If your car has a CAN BUS or you need to communicate with a CAN BUS device (like dashboard), you need extra 2 wires, CAN+ and CAN-.
    - If your gearbox is synchromesh and you purchased synchro kit, then you need to mount clutch actuator and connect it between the existing clutch line.
    - If your ECU support engine unload (ignition cut, retard, fuel cut) you need to connect signal wire from gear control unit to your ecu. If it does not, then you need to wire the ignition coil supply into the gear control unit (only if you want full throttle shifting)
    - With software installed and car running we recommend a fine tuning on a dyno to test everything in safe and controlled environment.
    It takes around 20-40 work hours to install this system in a car.
  3. How fast can this system shift?
    Realistically around 80 - 120 ms is possible on a dogbox. With synchronized gearbox (by GCU automatically pressing the clutch), you're looking at around 250 - 350 ms.
  4. What are the dimensions?
    Actuator assembly: 286 x 142 x 120 mm.
    Compressor: 220 x 100 x 170 mm.
    Air bottle (tank): 290 x 120 x 140 mm. 360 x 120 x 140 mm with all accessories included (safety switch, relay, pressure regulator)
    Complete kit weighs approx. 10 kg.
  5. What do you need from me before you can start?
    You need to measure travel of each cable for each gear. This is the most important step and must be measured very accurately.
  6. Is this system repairable?
    Yes. Most of the components can be easily replaced.
  7. Do you ship worldwide?
    Yes, we ship worldwide.
  8. Lead time?
    Kit will be ready to ship in 1 month.
  9. What are you payment options?
    We prefer wire transfer, however, paypal is also possible, but we have to charge extra 3.9% for the paypal fee.
    We require 1000 eur advance and the rest before shipping.
  10. How much does it really cost?
    - Base price for a kit is 3500 eur + VAT. 
    - If you have a synchromesh gearbox and you want our synchro kit, that is extra 700 EUR + VAT. 
    - Shifting cables need to be modified. If you want us to do it, that's extra 130 EUR + VAT + your original cables. We make new ones and use only the bowdens and gearbox mountings. We can also build completely new cables according to your drawing for 300 EUR + VAT.
    - If you want us to crimp the connector and provide the wiring that is also extra 100 eur + VAT. There are no other costs before purchase.
  11. How can I buy cheaper h-paddle shifter for my car?
    You can build your own kit, with your own components. We don't mind. We are happy to offer you only the parts you cant buy/make.
