Welcome! Nice build so far!

Un-stretch those tires(you're going to need more contact anyways) and replace those headlights and then you're :thumbup:

Already on it! Lol was either going to go with 245s or 255 up front and 275 in the rear. Headlights need work I agree :o

255/285 fo sho

Id like to run those sizes , only concern I have is without the stretch, the wheels poke a tad bit so if I run flush tires to rims, it'll poke and I want 0 camber, I was going to go with re11s or r888s.
255/35 18 front
285/30 18 rear
Any suggestions ?

cosmis xt006 18x9.5 +10 front 18x11 +8 rear

Or 295/305 fo mo meat yo.

Just roll them fenders lol

Isn't stock spec like 1.2 degree of camber? or something

I'll have too check once I put it back on the alignment rack. :confused: most likely going with 245/40 and 275/35s

IIRC rear camber is -2.0
Congratz! :thumbup:

awesome! thank you.

Stock rear camber-OE spec is Min -2.1degs Max -1.1degs

On tires.... No no no no, don't do it.

Compare:

225 45% 18 25.97 Stock Reference Size
245 45% 18 26.68 Stock Reference Size

You mention:
255 35% 18 25.03 -0.94"
285 30% 18 24.73 -1.95"

As deadeye mentioned, proper sizing on 18s...
255 40% 18 26.03
275 40% 18 26.66 OR 285/40-18 26.98" (with 11" width, go with 285)

Yes, with those offsets, 95% probability you're going to NEED a rear roll to fit any of these sizes.

so 255/40R18 front, 285/40R18 rear? I use to have 285/35R18 nitto 555s in back and it looked too meaty for my liking, maybe it was the brand of tire that made it look meaty?

edit: decided to go with 245/40R18 (25.7) vs 25.97 and 275/40R18 (26.7) vs 26.68 will that be ok?

very nice! Some nice stuff on the car/engine.

What are your goals for your retune?

thanks man! Honestly id be content with 500whp, even though I know the motor can handle more, I would be happy if I got to the 500s. Not really sure how far I can get with gtr injectors ..

welcome by the way

I was gonna say your injectors and fuel pump are holding you back (thats the good news and the bad news) spend $500-$600 on some 1000cc injectors and $100 on a 320lph pump and you'll hit 500hp.

What are you tuning with?

thanks for the welcome lol I'm using uprev, what power do you think I can get with the set up I have?

^I did 455hp / 420tq back in the day supercharged using a 255lph and 600cc injectors...I think the OEM GTR injectors are like 525cc?

If I was a gamble'n man (which I am) my guess would be 440hp / 460tq ... Your injectors will limit your hp outup and your added displacement will bump-up your torque...

🤔 okay cool I'll find out next week I guess, they're using a dyno dynamics which I heard reads even lower than a mustang dyno.

I'm late to the party, but welcome to the forum! That's decent power for lower boost, it must be a blast to drive :)
