Hello evom.


Wavetrac Front LSD diff upgrade will increase shockload versus

Stock helical lsd?

Worth upgrading?

450whp bolt ons.. track use

Thanks

I haven't run mine on a track yet, but I can tell you even for Street use I like my wavetrack far better than the stock unit. If you have the means, definitely go for it.

The OEM helical front diff is a good unit. For track use, you will see a bigger difference by upgrading your rear diff. http://www.teamrip.com/evolution-4-9...uild-services/

Not true. I have seen sub 400hp cars break the front
diff, they are junk. The rear diff is not a weak point, but a weir 12 plate conversion is the best deal for the money/longevity.

Wave track is the toughest unit out there and a great upgrade

Are you speaking of the diff in the transfer case or the transmission?

Weir 12 twelve plate is junk. They aren't a good design, and they fail. If you want a 12 plate, send it to TRE for Jon's maxlock setup. And the rear diff it's weak points. The post on the side cover for the carrier bearing gets smashed down, then the bearing is loose and the ring/pinion pattern walks all over the place.


The stock (LSD) front diff breaks from not knowing how to launch the car. For a road course car, an upgrade is not mandatory.

There are a lot more front diff failures than rear diff failures track or drag race period. I had the weir unit in the rear on my 800hp evo 8 and had no issues. I have upgraded to a kaaz LSD in the rear currently.
As far as the front diff, I have seen no less than 4 failures, some the whole carrier broke in half other wore out the spider gears thrust washers till they broke. Three of the four vehicles were sub 400hp. They are crap IMHO.

They only break like that when you launch them.

And of course your weir 12-plate is "fine", you only drive your car in a straight line..

Front lsd, Transfer case..

Just wanted to know if wavetrac can increase/ absorb more

Shockload compare to stock helical front lsd.

interesting to hear that OEM front helical is weak for some people. This is the first that I've heard of it, and I know quite a few people with 9s.

Wave track is a solid unit. The diffs I have seen break are mostly open diffs on the 8's and one 9.

Here is a helical diff that failed

Drag and racing and not launching the car right will explode it. Some who uses the Evo as intended (twisties car) will never have an issue.

Thats a pretty epic failure! If i had a shop i would make that a show piece. Whats even more impressive is he did it with only 320whp.

Doesn't take much when you side step the clutch off the rev limiter from stop. **** goes kaboom. The Evo is a rally car, not a drag racer...lol
