Hopefully I can be of some help to people who are interested in this modification. Feel free to chime in with questions, feedback or additional commentary. For the record, I drive a red 1996 240sx. It has 129k miles, no accidents, and bone stock. First off.Why would anyone want to perform this mod on their car? Well to the unsuspecting S14 owner our cars are filled with rubber bushings, both in the subframe and the differential. These rubber bushings help to eliminate or dampen and drivetrain noise and vibrations.

In english they help to make the ride as smooth and comfortable as possible. These rubber bushings, depending on how you drive your S14 have a limited life span, of about 40k to 90k miles, before its a good idea to replace them. If you are like me, which you probably are, around 115k miles you will start to hear some knocking of the subframe.

This knocking is because the rubber bushings have worn out so much that now the chassis is knocking up on the subframe. I had a good 2 inches of play around space where rubber should have been. An unwitting S14 owner will take his car into the shop and the mechanic will tell him, your bushings are worn and its gonna be a 1000 dollar job to fix. You say what the F?

He tells you well, the only way to get these new rubber bushings is to buy a brand new subframe from nissan, and thats why its so expensive. Most probably go ahead with this job. The mechanic didnt lie, you cannot just buy new stock bushings. Nissan offers Nismo bushings, these are fairly expensive, but less expensive than the completely new stock subframe install.

I thought there had to be another way, and Lo and Behold after exhausting searching on 240sx.org, I came across SPL solid aluminum bushings and differential bushings. What I found out in this forum and another 240 forum was that people said you will get alot of drivetrain noise and that it gets really loud. Even the SPL guy Kuah (nismo freak I think) said that it will get really loud on the street and even louder on the highway. I sucked it up and had them installed anyway. I thought, if I didnt like them, and the noise was too loud, I will just get the new stock subframe with rubber bushings.
