Nissan Skyline GT-R Subframes

There are two subframes in a Nissan Skyline GT-R, the front and rear.


R33 GT-R - 55400-24U00 (shows as being unique, fits early and late)

R34 GT-R - 55400-AA300 (shows as being unique)

Installing a later subframe in an R32 GT-R

From SubBoy on SAU

1, R33/R34 or S14/15 subframe. (I used a R33 non-Hicas subframe, R34/S15 subframes have more gusseting, I also welded in a GKtech subframe reinforcing kit.)
2, Offset subframe bushes (I used the GKtech solid offset bushes, these mount the subframe up a lot higher which is better for roll centre and will require a little "massage" of the floor pan on the front on either side of the subframe, test fit the subframe before mounting the diff and arms on it.....all will become obvious)
3, R33/S14 lower suspension arms (you can still use the R32 arms but will need spacers/washers to pack out the difference on the inside mounts
4, R32 upper arms (I made the mistake of buying brand new R33 top arms thinking they would be required.....but they foul on the shocks)
5, Driveshaft Spacers (I used the GKtech 10mm ones. There is some differing thoughts as to whether these are required, but I figured if the R33 subframe is 10mm wider on either side then I would put them in to avoid damaging the CV joints)
6, R33/S14 Tie Rods and Bushes (If you are getting rid of the Hicas by going to a non-Hicas subframe like I did you will need these and something like a set of Whiteline bushes to replace the ball joints that are in the hubs for the Hicas tie rods)
7, R32 ARB (seems to still fit, the mounts are spaced a little further apart)
GK Tech Offset Subframe Bushings

The GKTECH Polyurethane subframe conversion bushes are a direct replacement of the standard items and allow you to fit an S14/S15 rear subframe in your S13/180sx, aswell as R33/R34 rear subframe in your R32. The Polyurethane bushes also ensure that movement of the subframe is kept to a minimum. They eliminate axle tramp whilst also raising the subframe which helps to correct the roll center on lowered vehicles.
