Nismo Pro Gt Tt

[conan7772]

New 1.5 way diff installed last week.

Did the figure 8's and oil dump.

Did 300 km's without going over 70 km's and used throttle gently as.

Now done 500 km's and it's still very tight.

Going around corners steadily with moderate throttle it clunks causing the rear end to twitch.

No problems with heaps of throttle.

Does this sound normal ?

Cheers

Hi Alex, I have GT Pro 1.5way (not TT) in mine and its sounds similar to you. Especially on semi-slick tyres - lots of binding up and banging around. While it does lessen a little once run in, it never really goes away. The trick is to change the oil out for an oil with a degree of friction modifier in it. This will smooth the diff up quite a lot and make it far more streetable. When you put your foot into it though, the 16 odd clutches in it will still lock it up - so don't worry, it will still work like a high performance diff.

I used Redline 80-140W. But any good gear oil that has a friction modifier would do. The difference was noticable the moment the car was reversed out of the driveway. Serious.
