A few weeks ago I had my R33 Skyline Diff Shimmed By Ray at RE Customs.
Prior to this my diff would always single spin, so I was looking for a solution to this.
My original thought was to buy either a 1.5 Caz diff or I was also looking into the Nismo 2way.. Both of the mentioned diffs were approx $1500 - $2500 installed so some big dollars.
After speaking to Ray about some possible options he suggested that I could add “shims” to my original single wheeling Nissan Diff to tighten it back up and all for a very affordable price. (Under $400)
The diff can be tightened up using various shims in the diff as per the list bellow:
0.80mm
0.85mm
0.90mm
1.01mm
1.05mm
1.10mm
1.20mm
1.30mm
1.40mm
1.49mm
Based on the selected shim you get a various desired tightness to the diff.
I asked ray to make my diff tight so it was something similar to a 1.5 – 2way Diff.
This was achieved by placing 2 shims additional to the original ones (1 on each side) 1.10mm thick to the diff.
This in turn has come close to locking my diff.
All I can say is its fantastic!!! This is also a very cheap option to fixing a single spinning Diff, and I highly recommend it to those who are sick of a single spinning diff and want a cheap replacement and fix.
I will also add that I am not one for doing things cheap but this does not appear to have any bad affects and is still using the original Nissan gear.
I took the car for a drive on the weekend and through some tight corners
Felt like it was on train tracks. The whole car now feels extremely stable so it has certainly been a viable performance upgrade.
If you’re interested in having this done to your car, speak to Ray at Re Customs and he’ll be able to give you a price and book you in if interested.
