I've been told that Quaife Helical were the best rear LSD's but I want to get some input from the Forum. With other brands like Cusco 1.5 & 1.8 way (whatever that means) CARBONETIC Carbon (which sounds cool) Kaaz (which seems to be the lowest price) or should I just put a used stocker in there for $100???

My car is my DD and I Drag Race every chance that I get... So, which one???

 

i've got a cusco 1.5 way in the rear and i love it - power oversteer on corners when I gun it

 

Really, that's the only respone on this question?

Anyone else? I'm in the same boat as the OP

Dambikeracer - what did you go with?

 

TRE might be an option for you on the cheaper side of the house as well. Their RIP design seems to hold up to most of the spirited street drivers. I personally love the Carbonetics 1.5, best in the class. Look at most of the worlds best street/road racing cars (Skyline/EVO/SUPRA/for examples) out and they have them. I have heard a few things about Wavetrack as well, but don't have an opinion on it thus far.

 

The stock diff can take a lot of abuse.

If you want the handling advantages of a tighter rear lock up but don't plan on making like 600+ HP, I would just upgrade the rear diff through Shep or TRE for their clutch pack upgrade.

 

i have the upgraded shep rear diff. works great, super tight. drifting is easy. LOL BUT, do not use redline lightweight shockproof gear oil in the rear unless you dont mind it popping like all hell everytime you turn. i went back to the oem fluid and its quiet now for the most part.

 

Huh, that's what mine is doing and I just added the shockproof. It's more of a rumbling metal noise and vibration when making a slow turn. I recently grenaded my LSD in the T-case and just re-installed it and changed all the drivetrain fluid. Now my rear is noisy and I thought maybe I broke something in that too. Guess I'll just change fluid and see if that helps.

 

that redline doesnt have any friction additive or very little. i added some GM additive to it with no result. Diaqueen FTW!

 

I don't know about for the evo, but I've used the OS Giken LSD on other cars and it blew me away, I'd highly recommend it and they have a fantastic reputation as well.

 

Any reviews on the Giken for Evos???

 

I went with TRE rear diff w/ 1.5 way option. I would have liked to tried a carbonetic setup, the carbon disc clutches seem like they would take lots of abuse, but money was a factor in my choice for a TRE.

 

anyone tried the wavetrac yet?
