Any comments from the AMS guys on how this rear diff works

Hey Question my buddy has a supra his name is Reid Dawson and he has the Carbonetics diff in his car he loves it but what i really think is annoying is that you have to change the diff oil like every two thousand miles. And you have to buy that really expensive oil. My question is is that the same for the evo?

 

Its recommended by Carbonetics that you change the LSD oil religiously, but if you are planning on upgrading the rear diff, then you are probably in need of one, so should definitely consider the best. Things to consider:

1. More than twice the differential lock strength of metal LSDs
2. Low initial drag resistance and durability that is more than 5 times greaterthan metal
3. Acceleration control range more than 10 times that of metal LSDs
4. More than 30 times the thermal decomposition resistance of metal LSDs
5. More than 70 times the service life of metal LSDs
6. Noiseless performance

Straight from ATS/Carbonetics. They have been used in the race KD Autotek GTR32 (front&rear) for about 3 years now, and they are still going strong.

 

yea - those stats were why I was wondering if there were any responses on this rear diff

 

bump.. anyone have this?

 

I put a Carbonetics 1.5 way rear differential in Martins EVO 8. The car went on to win the Castrol Top Shop challenge a few days later. Its holding up very well, performs very well and overall the piece was very nicely made.

 

nice, thanks for the response. Would you say it's better than the Cusco?

What's the maintenance schedule like? I heard it's every few thousand miles or so?

 

It's not really better than the cusco, it just reacts differently. The main thing is the carbonetics is a lot quieter. The real draw back is the frequent maintenance, lsd oil change 2,000-3000 miles.

 

how would you say it reacts differently?

 

It's really hard to explain but the car feels more like a high Hp rwd car that you have to keep both hands on the steering wheel and be prepared to react w/ launching, counter steering and so on... I hope this helps.

 

oh you mean compared to stock? i thought you meant compared to the cusco

 

Here are some details on the Carbonetic Carbon differential from their website.

Yeah stock, cusco & carbonetics are about the same, I went with carbonetics b/c it's quiet, A- plus for me b/c my car is also street driven. I really keep up w/ maintenance changing the oil and lsd oil at the same time, and immediately after the track, so I haven't had any problems or issues.

 

haha dang though, every 1,870 miles!

Do you have a similar pdf file for the Cusco? Just trying to decide between the two. Also, how much will it be for installation at your shop? Thanks

The file is actually very interesting - though they don't say why, they talk about the low initial torque and gradual transition to lock - kiiind of similar to what I was gathering from the Cusco RS with the RS spring absorbing it initially for a more gradual transition as well

 

I think changing it every 1870 miles would be for a hard driven track car, im sure in a street car it would be less often but you would just have to see what the oil looks like to determine that. I cant find similar info on the Cusco. We'll send you a PM with a quote for install.
