Rogue Engineering G8X M2/M3/M4 Short Travel Clutch Arm

I occasionally check their site for something like this, and there's now a page for it. Currently unavailable but I emailed and they said end-of-February for an ETA.

I found a Supra assembly (clutch and brake pedals, and the housing they go into) for sale online a while back and sent those pictures from it to Rogue. They said it looked like the G series units but of course can't guarantee it.

I thought you guys might be interested in this. I am! Mostly to see if the actual height of it off the floor can be at the same plane as the brake pedal next to it. I feel like, right now, the pedal is too high up and I have to move my whole leg instead of basically just my foot. Otherwise I think I'm happy with it.

Not sure how the install would be. Seems like a couple of clips, pins get removed, and the arm itself might slip out. There will probably be videos for it eventually once a few people have bought it and installed it..

I don't have any affiliation w/ Rogue BTW just wish my clutch pedal was lower and pretty happy that there's a chance that can soon be changed. I'll take a guess that some Supra owners would be interested as well.

What would be some benefits of this?

Small changes to the geometry of that pedal arm. They could relocate where the slave cylinder attaches so that a little less pedal travel is needed to do the same job. Metal bushings supposedly to reduce freeplay. I doubt I'd notice the change in freeplay if any, and it's entirely possible that the reduced travel will make it more touchy. Some would say it lets you shift faster but I won't go there. Where it engages could change as well and how much travel there is until it gets there, but that's probably directly proportional to the reduced throw if any. Probably means more effort since the throw is reduced, not necessarily good either.

I'm in it if they can relocate where the actual pedal is, but that's a broad term, maybe call it the pad that screws onto this arm where your foot touches. To me it's too high up from the factory, oddly so. Even after 6 months I'm not used to it and want it to be about the level of the brake pedal. That would be my motivation for the change.

Everything else to me I'm sure would be different, not sure if better or worse. But I'll take it if the resting position is closer to the floorboard, as long as the other changes don't make it awful for some reason.

Did you ever get this installed?

Interested. I agree, I could never get my seat position where I’m completely comfortable due to the clutch, it’s ether too far back for the clutch engagement where I have all that travel but then too close for the brake.

No, it only recently came out and my last discussion with rogue was they didn't know if it'd fit, to give it time. Also the "feels like" temperature even late in the day here is 33F so it'd be a while before I'm doing any wrenching on the car that isn't required to be done.

Here is the Supra clutch pedal assembly: Part # 31380-WAA01

Here is a Z4 clutch pedal assembly: part # 35006883412

Here is a G87 M2 clutch assembly: Part # 35009504882

Here is the Rogue Engineering Pedal:

Tough to say. While the Supra and the Z4 are obviously the same unit, the M2 assembly looks slightly different and does have a different part number than the Z4 ?

If anyone is interested in being a guinea pig, I have an idea - IM me.

I'm hearing if it fits it will be the single most incredible mod you can do to your manual Supra. Even auto Supra owners will be fitting them I hear.

Spoke with Ben at Rogue, he's going to let me try the pedal to see if it fits.

Hope to have an update next week, fingers crossed.

Great news, it fits and works perfectly.

The difference is huge, throw is so much shorter, engagement and disengagement has a great feel, no more hesitation when releasing. I've done a ton of mods to the car, this is at the top, completely changes the entire shifting experience.

Highly recommend for anyone that has a manual.

Since I've done the bushings/pins before the install was quick and easy, maybe an hour. The hardest part is getting the top pin all the way in so the groove for the e-clip. It's hard to get leverage to be able to push in, plus it's a tight fit. I use a long vise-grip clamp to get the last 1/8" through.

You need to disconnect the knee airbag after taking the cover off (two bolts and disconnect of a connector to a small fan. You could do it without disconnecting but it would be a blind install and leverage will be near nonexistent. The connector has driven me crazy, you have to pull the top of the connector up to release the sides that lock it in place.

To do the install move the seat all the way back, fold up a towel and place it on door sill to provide padding on your side. It will still be a little painful on the side of your torso but not as much if you don't. You will be half in the car and half out, with your knees on the ground most of the time.

These are the instructions for installing Clutch Masters bushings/pins for the clutch pedal, they're helpful. It's nice they took the whole pedal assembly out to be able to show what it actually looks like because it's hard to see and understand the orientation when you're on your side and back looking up.

Pin with e-clip is at the top (delrin bushing are used in that hole), spring at the top needs to come off, which is easy. Right under the upper spring is in interesting pin that you have to twist to unlock so you can pull it out. This holds the master cylinder to the pedal. Below that is the return spring, attached to the pedal with another pin with e-clip.

About how far up does the clutch catch? Does it catch pretty close to when the clutch is all the way to top?

Also, how long did it take to install?

 

[tracer bullet]

Also would you mind confirming what I think I see which is that the pedal height off the floor is basically in line with the brake (and not an inch or two higher than the brake)?

Thank you, by the way, so much for being the guinea pig here.

"This is at the top, completely changes the entire shifting experience" Like the CDV delete and the aftermarket shift knob?

Did you measure the std and new clutch pedal leverage ratio before you installed it?

The pedal sits at the same height as the brake pedal now. Clutch engages and disengages right after coming off the bottom and right before the top. It removes the dead space at the top and bottom.

Took me just about an hour, but I've taken the pedal off before. Length of install is dependent on how well you work in tight spaces and uncomfortable positions.
