I picked up a set of Evo 10 hubs after getting some helpful advice. I did some test fitting today and they do indeed look like a direct bolt on.

You can even see the lower joint is rasied.

Evo 10


I did run into an issue and was wondering if anyone has been able to overcome this?

I want to keep my ABS and ACD; however, the Evo 8/9 looks to has a passive sensor with a metal ring that fitted to the axle and the Evo 10 has an active sensor with a magnetic encoder that's built into the wheel bearing. I thought about using the Evo 10s wheel bearing, ABS sensor, and wiring it in. However, the EVO 10's splines are bigger and I'm not sure if my Evo 8/9 ABS ECU can read the Evo 10's sensor. If I swap out the wheel bearings, I will not have the magnetic encoder that's built into the wheel bearing.

Thanks for the help in advance.

Here are some pictures of the hubs

You'll just need one of these to translate the encoder back to 8/9

 

 

Do you think it would be possible to machine the evo x hub to accept the 8/9 abs sensor correctly?

 

Hmm, well this does answer a few things for me and my billet uprights. They certainly look like it would be no problem to fit but I dont think I have an abs solution. Can you tell me if they are in the same position but just need a different clock position for the screw?

 

but why?

 

I'm sure anything is possible. However, it might be costly and near impossible. Due to the sensor being clocked differently, 8/9 has a much bigger an shorter sensor, and its located in a different position.

Are you asking why do it? or why keep the ABS?

Long and short of it, the Evo X hub and arm allows for better roll center geometry for the Evo 8/9. The ABS sensors allow for a functioning ACD system and I prefer ABS as it helps prevent flat spots.

 

Whats the bumpsteer like with the X knuckle? Would be pretty luck if it's even close considering the X has a different rack and subframe (which dictates where the rack is mounted..

 

I'm not sure yet? However, I'm not worried about bump steer because I can correct it with my tie rods and spacers.

If I can't figure out a way to to keep the ABS, I may not run it.

 

I plan on doing this myself, along with evo x LCA. I don't see an easy way to keep the ABS without plugging the stock evo x hole, welding a piece of steel in the location of the stock 8/9 sensor, and drill it for the 8/9 sensor. I think anything else will be a big pain and a lot of finger-crossing to hope the different sensor / rings and ABS system can talk to each other.

But I am keenly following your thread for easier solutions.

 

Part of my concern with this idea is making the knuckle weak because you will need to remove material. The 8/9 sensor is fat and short.

I hope someone has an easy solution.

 

I was starting to think you could go full X abs but then that dang ACD/AYC integration...

 

I could be completely wrong and it might work??? Looking for any ideas. I could see going EVO 10 ABS ECU, but then you would need to figure out the rear ABS Sensors. Just maybe the ABS ECU send the signal to the ACD/AYC ecu.

 

Evo 9 (with ABS) Wheel speed sensor feeds to ABS-ECU and from ABS-ECU to ACD-ECU.

Evo 9 (without ABS), the Wheel Speed Sensors go straight to the ACD-ECU pins (C-139 pins 6, 7, 8, 9).

Notably, the Evo 9 ABS-ECU and ACD-ECU have a whole lot of signals going to them, a lot of which are shared and the wheel speed communicated from one to the other.

Swapping the ABS-ECU from Evo 10 could be quite complicated when you start looking at all of the signals that go into the ABS module and try to determine what the different scaling/ranges are between the signals. Additionally, maintaining the Evo 9 ACD-ECU operation intact could be easy or complicated depending on how the Evo 10 ABS-ECU or Evo 10 Wheel speed sensors work.
