The front subframe is one of the mounting points for the front suspension on an R32 GT-R. Eight bolts hold the subframe to the chassis. The subframe provides the mounting points for the engine mounts. The steering rack is held in to the subframe, the sway bar (anti-roll bar) is bolted to the subframe.
The main components of the front suspension.
- Tension Rod (54468M RH, and 54469 LH in the drawing)
- Lower Control Arm (54500 RH, and 54501 LH in the drawing)
- Upright (54590 RH, and 54591 LH in the drawing
- Upper control arm (54524N RH, and 54525N LH, in the drawing)
Many of the suspension parts across many of the Nissans are the same. There are some parts that are superseded. Some that are split by years across the models. Most of the R32 suspension parts, GT-R, and GTS/GTS-t are the same. Some are specific to the all wheel drive cars.

The problems with the R32 GT-R suspension according to Mike Kojima.
"Read it and weep keyboard tuners and JDM fanbois. Contrary to popular belief and legends of awesomeness, the R32 GT-R has really shitty front suspension geometry. Very short, highly angular links result in a stupidly poor camber curve, bad roll center location, seriously bad lateral instant center location, a lot of scrub and too much anti dive. The result is serious understeer and torque steer with big tires. (Just ask Takumi in Initial D) and worst of all, jacking. A lot of the problem is the upper link location as shown in this photo I borrowed from Geoff Raicer of Full Race. The upper link is super short, angled forward and canted upward. This photo is at full droop, imagine how bad the upper link angularity is at ride height. I think some Jr. Nissan engineer was trying to design a suspension with more negative camber gain when the wheels were turned and he either didn't know or care about other things. I want to kick this guy in the nuts. Besides having a retardedly ungood amount of negative camber gain, the upper link angularity means that the lateral instant center is very close to the wheel centerline and the roll center is very low. When an attempt is made to correct the roll center by moving the pivot for the lower arm, the lateral instant center gets even closer. This means that the front suspension wants to jack with a lifting moment that also causes wheel tuck. Yikes this is bad! We have photos of this happening to the car and other R32's on the track. What was leading edge technology in the early 90's sucks now. "

Problems with the R32. To much rear antisquat and to close front lateral instant center.

Short of sourcing Group A subframe and mounting brackets, are there any current aftermarket suspension parts that correct this?
