what offset do i need?

[CurlyStooge]

I want to get 17X9s in the front and 17X10s in the rear. I'd like to know what offset is needed for these. I own a 97 base model 240sx. I'm probably going to need to do the 5lug swap to use these, unless someone knows of wheels in these sizes that are available in 4-lug. If I can't fit 10s in the rear, someone let me know what the largest size I can fit is, thanks!

Look around, offset calculators are easy to find.

If you don't mind me asking, why are you putting such wide wheels on your car?

offset calculators wont tell me how far out i can extend the wheel without it bulging out like mexican rims. I'm doing it because im swapping engines eventually and dont want to buy another set of wheels when i do, because when I do ****, I go big, especially since I get free mechanic work and get parts at cost.

[CurlyStooge]

Yep, thanks for pointing all that out, because the car will be made for strait lines, hence the fact that I'm going to be using a T78 or T88 on it.

A 9" wheel in the front will require a minimum of a +20mm offset, but I'd go with less for proper clearance. Going that far will push the wheels past the fender edge, looking like the "mexican" car you're trying to avoid. You'll still have clearnace issues when using coilovers too. In the rear, a 10" willl need at least a +30mm, again giving you the same problems. Simply put, that choice is too big. A 17x8 and 17x9, +30 and +32 would be my choice for the maximum, but even then that's a lot of tire that's not needed. Drag 240s run much smaller sizes in diameter anyway. Good luck with whatever you deicde.

i rescent that "mexican" look.... it's the "El LOCO" RICE Look ESE!!! and i see some white boys with those wheels also.

So que barrio ese!!!

LMAO all the above statement is a joke.

if you are going in straight line (ie drag racing) i would not put a 25+ pound wheel + tire combo at the front....

that is why god invented skinnys (sp???)

[CurlyStooge]

yep, id use skinnys at the track if it was a pure drag car, but its a street car too, and skinnys dont work too well on the street. . I figured youd point out that I shouldnt be using 17 or 18s on a drag car before mentioning skinnys since you thought it was a pure drag car.

[CurlyStooge]

You keep changing your story. Perhaps we're not being clear enough with you.

"It's a drag car, I'm putting a huge turbo on it."

If you put 9" or 10" wide tires on your car, it's going to be difficult to steer, unreliable, and slower. If you're planning on putting 1000hp to the ground and you're going to be trailering the car to the drag strip on the weekends, this might be worth doing.

Of course, if that's the case, you should probably use a Mustang or a Camaro instead. It's a heck of a lot easier/cheaper to get to 1000hp with eight cylinders instead of four.

"It's a street car, too."

Then you shouldn't put enormous tires on it. You're never going to be able to make the kind of power that tires that large would warrant streetable.

Also, unless you're planning on spending large amounts of money on super lightweight wheels, 18" wheels are just going to slow you down.

I think I'm not being clear with you, hence the reason your replying with an atitude like I don't know what I'm talking about. Also, I'd go with a camaro or mustang, but Mustangs (unless its the 5.0 boxy bastards) wont do **** lower than 12 with anything less than 30 thousand in them, is that cheaper? If you think that's off, ask Larry at MV Autos, he used to own a 95 5.0 (last year I beleive, might be a 94) and had about that in his, and only ran mid 12s.

Well, be clearer, then. You've said "the car will be made for strait (sic) lines", strongly implying a drag car, and you've also said "its a street car too". These two statements are contradictory.

Are you building a dedicated drag strip car that will never be driven on the road, or are you building a car that you intend to drive around and drag on the weekends?

hence the reason your replying with an atitude like I don't know what I'm talking about.

Your inexplicable desire to put nine or ten inch wheels on a 240 indicates that you don't know what you're talking about. You also don't seem to know how to measure, which doesn't do much for your credibility. I am very open to being proven wrong, though.

I think you're going to be hard pressed to get a 240 under well 12 seconds (and and have it streetable and not have to rebuild it every six months) for less than that.

If you think that's off, ask Larry at MV Autos, he used to own a 95 5.0 (last year I beleive, might be a 94) and had about that in his, and only ran mid 12s.

I'll be sure to bring that up with Larry next time I see him.

im going to measure (in the morning if i remember) whats left on the inside of the tire and the amount of space on the outside before running out of the fenderwell. I'll get Larrry's number if you'd like to talk with him about the pos ford he used to drive (bought a camaro z28 and put nitrous on it, and its already faster than the old stang with over 20-30k in it), so you dont have to come down from road island. :rolleyes
