Trying to make my GTR more sharp (handling-wise), suggestions ?

[cobrAA]

Here's what I have so far:

Front tension rod, FUCA, RUCA, hicas delete with tie-rod oem delete ( replaced with tension arm), I believe I have subframe collar , front and rear strut-bar and Apexi N1 coilover.

Since, I'm pretty much done with my power mod ( Unless I put another +5k for stroker or efr turbos..) I went ahead and bought:

Solid rear diff bushing, solid shifter bushing, center roll adjuster, steering solid bushing, eccentric lockout kit, engine damper ( because changing the engine support is a little too pricey in labour) and was debating if I should go solid rear subframe bushing to replace the collar and Nismo tranny support mount.

Is there something else I'm forgetting ?

What alignment specs are you running?
When you upgraded the RUCA, did you delete the eccentric bolt kit?

What about sway bars?

You would get a stroker for 5K in parts alone, MAYBE and another 5k in parts for the efr lol

turn the boost up you'll be fine.

Yup your right! I forgot about sway bars. I got the cusco uprated.

And thats why I said +5k ( I'm well-aware of the complete cost)

tune the setup you already have. u have all the parts u need to have a super tight car. try adjusting your front camber. i know my gtr loves heavy negative camber upfront. i go through tires like crazy but its the way to go. little crazy at hi speeds but you get used to it.

Increase your caster.

Word.....

Ridiculous camber is pointless and a tire eater. You know what 7deg of caster is? Camber on demand. You dont want more than 2-3 degrees in the back either, it also makes the car twitchy at high speeds and kills your straight line grip.

Poly eurathane bushings will suffic for the subframe. Solids are exactly that, too solid lol. With a good suspension set up our cars ride hard enough, no need for solid bushings unless your drifting or have 800hp.
The additional bushings you got will help. Good tires and proper dampening on the struts and you should be good.
In the same as you, never happy and always want to make it better
Then a friend comes in the car and loses his mind. Have to take a step back to really understand how we have pushed our own and the cars abilities.
Steering bushing is on my list

[cobrAA]

I have direzza II tires which i think are well-rated so I guess only thing I need to do after all these is to ''tune it'' lol !

[cobrAA]

Theres that bar that runs along the floor just in front of the rear seats to stiffen the chassis. I can't remember who makes it, though. this is the pic of it

DoLuck room bar.

If you don't have a room bar installed and you jack car up on front jack point, it's hard to open, close door on jacked up side of car. If you fit a room bar and do the same procedure, you can open, close the door without it fouling hook in back of doorway. Basically what a room bar does is reduce chassis twisting when cornering. If chassis is old (around 200,000km+), it's a must have mod to restore chassis rigidity.

Same with bracing across the chassis, length wise (bracing can be bought from HKS, Do Luck, etc), as the stock floorpan is a thin single piece of sheet metal.

Also can buy a whole chassis brace kit (strengthens chassis for racetrack use, without fitting a rollcage or if chassis has done high km) -
