Installing [BINARY] seat lowering brackets is straight forward and can be done with hand tools

First things first – you need to be able to distinguish between Drivers Side Brackets and Passenger Side Brackets. There is only one bracket that is shared for both seats, this is the front center bracket. The same part is used on each seat. All the other brackets are unique to each side. Passenger side brackets have ONE chamfered (angled) corner, that is how you tell them apart from the drivers side parts.

The pictures below showing removal of the seat actually show the [BINARY] lowering brackets, not the factory brackets. This is because I didn’t want to re-install them to show how to remove them:eek:

1. Remove the center console by opening it up and removing the two screws at the bottom of the compartment. Then “pop” the front edge up by pulling straight up near the shifter. With the E-Brake up you can remove the console. You may need to disconnect the IC spray button.

2. With the console out of the way you can access and remove the center mounting bolts for the seats. Use a 14mm socket. Also remove the two front mounting nuts, and the outside mounting bolt. You’ll need to pop off the plastic cover from the outside. With the 4 mounting fasteners removed you can pull your seat out – once you disconnect the seatbelt warning harness (wire) underneath the seat.

3. With the seat removed from the car you can now remove the factory mounting brackets from the sliders. This is done with a 6mm allen wrench. They are pretty tight, so I use a crescent wrench for leverage. There are 4 bolts, the 2 fronts are easiest to access by sliding the rails all the way forward. The 2 rears are best accessed by sliding the rails all the way back.

4. Factory “skyscrapers” booo.

5. On the front of the sliders there are plastic caps, these are held in place by a small screw. Remove the screw, it interferes with the lowering brackets. This only has to be done on the FRONT of the sliders. The rears are ok.

6. Install the [BINARY] Lowering Brackets using the factory bolts and supplied nuts. USE BLUE LOCTITE. The images below show the correct orientation.

7. With the [BINARY] Brackets installed you can put your seat back in. Adjust each bracket so it aligns with the mounting stud/hole. The factory sliders use slotted holes to create some flexibility for alignment. The fronts slide side-to-side, the rears slide front-to-back. The [BINARY] Brackets also use slotted/square holes, like the factory brackets to allow for proper alignment. Once everything is lined up re-install the factory bolts/nuts, tighten with the 14mm socket. The bolts/nuts for the slider-to-brackets can be tightened in place also. Torque values for the fasteners can be seen in the images below.

8. Re-install the console.

9. Enjoy your EVO in a proper motorsports style driving position – the way it should have come from the factory.

UPDATE:

I’ve got some feedback about two issues: harness eyelets and the adjustment lever.  So here are some pointers for these two issues.

1. Some harness eyelets require modifications to create enough clearance near the center tunnel of the car. This can be done with a hammer, just make a slight impression in the tunnel where the interference is. A washer can also be placed under the rear center bracket to lift it slightly.

I also have compatible harness eyebolts available. They are custom made as the standard seatbelt ones that come with a harness are not the correct thread size. I tried to help a buyer find these and they weren’t readily available – so I got these custom built.

2. The seat has around 15 positions front to back, starting with position 1 at the full front orientation. Of these 15 there are some, around 5-9 that the adjustment lever interferes with the floor support a little. This can be fixed quickly and easily by slightly bending the adjustment lever.

First remove the adjustment lever by using a flat blade screw driver to pop off the C-Clips which hold it in place under the seat.

With the lever removed mark the spot for the bend at 4 inches from the front on both sides of the lever.

Use a vise or some large pliers to bend each leg of the lever around 10 degrees.

With the lever modified reinstall it on the seat and pop the C-Clips back on. You are good to go!

Binary Recaro seat lowering brackets for EVO VII-IX

The Original – Binary seat lowering brackets for the stock Recaro Seats found in Mitsubishi Lancer Evolutions VII-IX.  These work on all global models of the CT9A Chassis, including: USDM, JDM, EDM etc; any EVO 7-9.

These brackets replace the existing factory mounting brackets and allow your seat to be dropped by 1.5 inches retaining the stock sliders.   The improvement in driver position IS MASSIVE.  The 1.5” drop makes all the difference and creates a true motorsports driving experience.  Your eyes will now look directly through the dash and make you focus down the track instead of directly in-front of your bumper.  Your arms will have a more natural path to the steering wheel and the shifter allowing you to comfortably perform fast paced motorsports driving techniques.  The lower position of the hips will create more clearance for your legs beneath the steering wheel giving you room for heel-toe downshifts, as well as better alignment to the pedals.  An obvious benefit is helmet clearance for us tall folks.  Overall the car will finally feel like a proper sports car, or even a go-kart, you won’t feel like you’re driving from a high-chair.

These are the original EVO seat lowering brackets – with hundreds sold and tested throughout the world.  These are not knock-offs made from cheesy unfinished stainless steel finish.

– CAD designed.

-  CNC laser cut.

-  CNC formed.

-  Powder Coated.

-  Included all required hardware.

-  Install with simple hand tools in under an hour.

-  Creates a true motorsports driving position:

- increased helmet clearance

- more clearance for heel-toe

– improved pedal alignment

– keeps eyes looking down the track

– allows for better turning and shifting response

HEAD TO THE MAIN BINARY SITE TO ORDER THESE!

NOTES:

A few positions fully forward (for really short folks) are not compatible with the brackets.  The sliders end up stopping against the chassis mounting hardware.  So be aware of that if you run your seat all the way to the front.  People 5′6″ have them installed and are still able to use them in their preferred seating position, so it shouldn’t really effect too many people.

Harness eyebolts from aftermarket harness may have clearance issues, it depends on the brand and your seating position.   This can typically be resolved by minor grinding of the eyebolt and belt mount bolt.  OR, you can use a Binary Eyebolt which replaces the chassis mounting bolt for the inside rear bracket – found under the center console.  This requires running without the center console.

Here are a few reviews taken from literally hundreds of satisfied customers.

This is one of the first mods I’ve done to the Evo. Going back and forth from my DSM to the Evo, I felt like I was driving a truck when I’d sit in the thing. haha.

I’m enjoying the Evo even more now. I was so excited I was making people sit in my seat at a local evo meet last night. You might be seeing a few more orders coming.

Overall……..excellent product Jared. I look forward to future products from you.
