Sad update: some piece of shit broke into my car over the weekend to steal the airbag. Broken window also.

Some people are royally f$#ked in the head. Hopefully the airbag accidentally blows up in their face. :bonk:

Well today isn't entirely bad news I guess. Wavetrac LSD just arrived. This thing feels hefty, I'm so excited to get it in the car.

I've been looking into the wavetrac for my DC2, the design is innovative and I like how it can shift torque in all traction situations. The fact that it's tunable is also nice.

I think the Si can benefit from an adjustment in initial torque.

That was partly what sold me on it as well. It was easier to get than the MFactory diff but I also really liked the ability to still power the other wheel in a one wheel zero traction scenario.

The way it transmits the torque wheel to wheel is very cool. The ramping effect leads to a smooth engagement from the (non-traction) wheel to wheel. Smoothness is key. It keeps it from needing to shift power rapidly back and forth.

Add in the ease of swapping the spring and you have a really tunable traction enhancer.

Been debating a LSD upgrade with what I'm going to have to do anyway. That thing looks mean... tell me more

Basically the Si LSD and other aftermarket helical options can split the torque between the two wheels at a certain bias ratio (X:1), but in cases where one wheel has zero or near zero traction, all the traction is lost through that wheel (X times 0 = 0). The wavetrac has an internal mechanism that adds internal load to the zero load axle, which allows you to send power to the other gripping wheel.

Problem is I don't see a way to install this into an Si trans, which uses 14 bolts to secure the final drive ring gear to the LSD. The hatch and aftermarket options use 10 bolt ring gear mountings. I think in order to use this in an Si trans you'd either need the final drive gear from a hatch/base trans or an aftermarket final drive from MFactory. I haven't confirmed if their final drive kits use 10 bolts but I'd assume so if their LSD does.

Sounds like it's simpler to stick with the stock SI LSD, in my case. Unless I run into issue with it.

I think so yeah, with a proper suspension setup I don't imagine you'd have any issues with it.

I do plan on doing the front sway bar, anti lift kit, front end links. While I'm doing the whole trans repair thing. Coilovers are on the list but most likely that'll be awhile.

I should probably take the time to do the oil pump gear, while the subframe is off. If the clutch looks worn I'm going with a eddy stage 1 type R disc as a replacement.

Are you still on the fx350? How many miles you got on it?
