UPDATE! The front mount for the CX7 arrived and look fantastic! Everything fits perfect (not tested on car yet) but I forgot to order the correct length shoulder bolts so I'm ordering now and will have monday. Today I also worked out my design for the push-rod mount on the trailing arm...

Ya thats my same logic. Touching on the power capacity of the rear diff system...I have more hope. Newer cars with this front biased AWD system are using a simple but clever way to be able to apply more than 50% torque to the rear wheels. The rear differential ratio is ~0.7% higher than the...

About those DSS rear axles... The shaft diameters are different for left and right...this is not by design. I talked to DSS about this...basically they said its fine and they used what they had available on the shelf from older MS6 production (yes that also means the MS6 rear axles have...

Another Update: Rear axles from DSS arrived. These are "700hp" rated axles per DSS. Doggo approved Axle fitment is good with lots of length adjustment range for more or less camber than the current -2.5 degrees. I also opted to have the wheel speed rings placed on the inboard side of the...

Another update: Transmission is still in progress. Have had some difficulties with shims and such, getting the bearing preload setup. If you are doing any trans work or differential change be warned that Mazda is discontinuing the various thickness shims needed for the bearing races. I...

Now the "tuning" for the rear diff is a whole different story. OEM ECU vs Motec ECU makes a huge difference and how much control you want. I want full programmable control so I'm going full custom setup. Working in tandem with the Motec, I am investigating a standalone controller from Syvecs...

Is this before or after the "shit everywhere scene" hahahaha

YOU CANNOT USE THE MS6 REAR SUBFRAME...you might aswell jsut fab your own subframe at that point. The easy solution: Use the CX7 subframe (the inner frame work that bolts to the chassis only). Then use the control arms and trailing arm from your MS3. The rear differential is made up of two...

Speed6 will not fit, it is very different

Lastly! I will be rebuilding the speed6 trans this coming week and getting ready to install it into the car. I attempted to rebuild the t-case I sourced but found it had questionable gears. Probably fine for a moderate street car but for a high power racecar its won't cut it. If anyone has a...

Progress Update...3 of 3 I did some CAD modeling aswell. Made an edit to my CX7 Differential Mount Fronts: Working on a 2-piece design so that the parts are simpler and can flip to work on both sides. Will be 3d printing and checking this week. Also designed a crashbar with integrated...

Progress Update...2 of 3 With the rear arms done, I could reinstall the arms and bearings to get my rear axle lengths. In doing this I had to make sure I was using proper surfaces to base my lengths from. Differential Side: Measuring off the face of the seal that is more of a face vs the...

Progress Updates...1 of 3 of them! Firstly, I got my rear trailing arms back from the machine shop. Look pretty good and fit great with the CX7 bearing hubs. They welded the original holes then post machined the new holes for the CX7 bearing hub. On the back side you see that the...

Same flange thickness 0.227+/-0.005

2 of 2 progress update: Images 4261, 4260, 4263: Here is an external comparison of the CX7 and MS6 rear differential. There are two major systems in the rear differential. The Gear housing and the Clutch housing. They bolt to each other in the middle and share the same gear oil. From what I...

1 of 2 progress updates: The billet rocker arms arrived! They look amazing. I've pressed bearings into one of them to do a bench test assembly. Everything fit togethor as expected but the shoulder bolts are a tad too long. Not a big deal though. The attached images are "half" of the...

No progress on the car last weekend, but parts are arriving! SendCutSend is pretty cool for this smaller one-off projects. Steel mounting brackets arrived for the rocker arm rear suspension. Everything fits togethor as planned and looks great. The coped bracket and bends on the big triangle...

Haven't been doing to much through the holidays, but trying to get back on the wagon here: So I pulled the wheel bearing out of the trailing arm to test fit the CX7 wheel bearing and see how the MS6 rear axle fits... Its doesn't on both parts. 1) The MS6 axle is jsut a bit too long so the...

MS3 differential doesn't cross over to the MS6 due to the T-Case interface with the differential
