FD wheel fitment
 
19" x 9.5" - 25 - 5/114.3 BACK
19" x 8" - 30 - 5/114.3 FRONT

Will this work without rubbing issues? if not what would I need to make them work?

Or

18" x 7.5" - 45 - 5/114.3 FRONT
18" x 8" - 40 - 5/114.3 BACK

sorry.. I don't know much about rims.

This is a sticky at the top of the page... It allows you to figure out what rim width/offsets will fit. Another major contributor to fitment is if your car is lowered and if so how far. Hopefully this will help.

This will not work without fender rolling and you will also have to stretch a tire on the rears, like a 225 or 235.

This will work just fine, but is pretty small width wise. You are not going to be able to get a wide tire on these wheels. This may not be an issue at stock hp but depending on your hp goals you are going to need wider wheels then 8" out back.

No you won't. I run a wider rim and tire with the same offset, rolled (not pulled) fenders, and I'm low (no wheel gap).

If you have rolled fenders (front and rear) you should easily fit 255s on the front and 275s on the rear. Just keep the tire diameter in 25-25.7" range, preferably closer to 25 in the front.

To be clear I'm talking about these:
19" x 9.5" - 25 - 5/114.3 BACK
19" x 8" - 30 - 5/114.3 FRONT

Thanks guys, I am right now running stock suspension.. In the market for suspension but don't really know what to get. Can you guys reccommend a good set up if im going to run these rims in 19 or 18? and I was looking to go for around 450hp with my greddy t78 turbo swap in the process. I really want these rims but which size do you guys reccommend?

theirs a difference between being able to fit it and it actually looking proper/flush

Would that sizing look proper/flush

What? a 275 on a 9.5" will be "proper" and considered conservative, no stretch at all, and it will fit flush with rolled fenders.

Theirs no way a 9.5 +25 on a 275 tire would sit flush, unless you ran camber. I am not calling you out but what i think is flush might be different then what you think.

ahh I don't know who to believe!! haha but what if I went with the 18's would those be ok with a fender roll in the front? I want to go with the 19's but what else would I need besides a fender roll?

18s vs 19s wont be much different if you keep the same tire diameter (especially if you aren't stretching tire).

You can believe who ever you want, but heres the deal.

My conservative setup in the rear I run a 275/40/17 on a 17x10 +38. The equivalent outer bound in a 9.5" width is +31.6 . I can easily fit a 7mm spacer on mine. So that would be equivalent to a 9.5 +25. Granted I do have completely flat fender lips.

The fronts aren't even a question for me in 8" +30. Those will fit with a 255.

I cannot 100% guarantee this fitment because I have no idea about your suspension or its setup (ride height, camber, caster). You will just have to try. Most likely they will fit. Worst case, you make them fit.

thanks burtoncr. I want to run 19's. Like im not going to go into racing and all that. I will be around 400hp with a t78 single turbo conversion and im going to keep stock suspension.. don't really want to race but later on i have plans to make my car a show car. so the 19's I would need front and back fender rolls and what tires would you reccommend? thanks for the help

burtoncr 07-15-08 03:10 PM

Crap. Nevermind then. With stock suspension I have no clue. If you need to roll the fenders you are putting the tire pretty close to the fender and that combined with stock springs will most likely rub. I run coilovers and very high spring rates so I never rub.

xplosive 07-15-08 03:35 PM

what would you recommend for suspension? I was going to buy some engine parts but I can use that to buy suspension parts so the rims would fit
