Default Anyone running 325/30/19?

I see 325/30/19 is almost exact diameter and circumference to stock oem 275/35/19 for rear tires. I want most aggressive setup possible so I'm wondering if anyone else went this wide and what offset? I will be lowered on swift springs as well so I'm concerned with running. Also, could I run stock 255/35 up front still, or will handling be affected with that stagger?

Doubt it will fit. It would have to be tweaked perfectly and you don’t have have the adjustability of coilovers.
Probably will scrub on the coils themselves if you run a “normal” offset.
Prob will scrub on the fender if you run super positive offset unless you don’t lower car much.
May be both?

Does that one BC racing black rcf have 325?
The offset of rims would have to be custom and measured just right.
Mask mike figs? He set that car up.

Plus your car gonna be all squirrelly with that much stagger.

305s are the largest size I've seen in either 19s or 20s. I'm running 295/30/19 on my ISF with stock RCF wheels. See there two threads:

yep that black rcf with bc racing rims is running 325. It clears since the wheels are wide themselves , no meaty sidewall. I think it almost looked stretched to a degree. You’re right, has to really do your measuring and tweaking with offsets , suspension and even tire brand since they all look different even with the same size tire

the biggest reason I moved to the rcf platform from the ISF it that I knew this car was made to fit some wide tires / wheel combos.

So should I go 305/30/19 in rear, 255/35/19 in front? Will this fit on springs? 325 might be tough I guess.. would be bad *** though.

This! ^^ I had 315 rears on 12" wide wheels combined with 255 fronts on 10" wide wheels and car was really twitchy. Went down to 11" wide rears with 305s and now car feels a lot more stable.

yes , easily. my friend is running exact same tire set up on his swift springs as well. he actually got rear camber arms just to make it look a little more flush by pulling some positive camber in the rear for 305 .

yeah, wider is not always better. you're set up looks amazing due to your custom offsets. i wish i can run something wide up front but i don't want to tear up my fender liners , rub or any noises . function > form in this case.
