18X11's in the rear?

[240sxrb25det]

i was wondering what the biggest size anyone is running in the rear of their 240 (i got a s14) i want to run some 18X11's if possible, and 285-295. i couldnt find anything about wheel sizing. and if anyone is running this size what offset are you using. i dont mind flaring the fenders but im def gonna need the meats in the rear.thanks Dane

there is no point in doing that but for looks...

If you want good grip then there is no need to have anything that wide as the price for tires is going to be F-ing outrageous....just get some sticky tires that are not so big. A wheel that big will be almost IMpossible to find as well as tires being nutty $$

[240sxrb25det]

18X11's arent that hard to find and 18X10.5's are easy to find, but with a decent sized single turbo on my motor im gonna need something big for road use, mo matter how sticky the tires are you still need surface area. tires are gonna run 250-300 a pop for the rear...which isnt that bad. but do u know what the biggest u can run is?

candela, what you say is true, but don't you think that you need fairly large tires if you're doing a crazy RB build up for drag racing? Although I probably wouldn't go w/ 18s if I was going for drag racing. . . 11's are pretty crazy, and probably not absolutely necessary, but you can fit 18x9 w/ 275's on the S14 if you roll out the rear fenders a little. That's what we're doing w/ our demo car (for shows and what-not). For actual performance, we're talking about getting 17x10's. . . we'll see how those fit. 275's are HUGE on the 240, though, and unless you're talking about over 500hp is NOT needed

[240sxrb25det]

underground you would go with the 17's? is that just to have more sidewall? i kinda wanted the look of the 18's but if the traction would be better ill def go with the 17's. i have a 2jz in my 240:eek: i have yet to drive it with bpu+ and im running 245's in the rear now, so i figure if i buy the rims now and put som good size tires on it itll be all goodwhen i go single this coming summer.also what kinda times do u run with the 26 in ur 240?Dane

Hi,

17s in the rear are the best for drag setups. We only went with 18's because we are sponsored. But for our drag setup, we are running 17x10 5Zigen FN01R-Cs.

On our 18x9's in the back we are running BF Goodrich Drag Radials, which are in my opinion, the best on the market. I wouldn't run anything else.

A 275 is probably about the biggest you can go without having to roll the fenders. On our car currently, the 275/35/18 is really tight and we are having the fenders rolled for them, but it isn't necessary.

With a 11" wide wheel, you are going to have to go with widebody fenders. I am not saying its a bad idea, because I believe in going with the widest wheels possible.

But unless you are putting down 600HP+, there is really no need. a 275/(35 or 40)/17 is the most common size for the Skyline GTR guys.

On the 240SX, I think the 17x10 is the most efficient wheel for the high HP cars. This is my recommendation and I'd run a 295/35/17 if you can get it.

Take care!

no....

I mean the only reason to really go wider is because mroe manufacturers make stickier compounds in wider sizes. THe contact patch doesnt get bigger if you go with a wider tire as 240 said. The surafece area will in most cases remain the same, so why go with somethign so huge? It will look cool IMO :ylsuper but that does not mean performance or grip just because you can get a 275+ on a 9"+ wheel on the rear. If you are draggin it then run slicks or a decent sized drag radial like underground suggested, but going so large does not make to much sense to me...

I would have to disagree with you on one of your view points.

Bigger tires do mean more grip. This is the whole reason why Vipers are not driving around on 16x6 wheels!

The goal is surface area and a bigger tire will provide this. With RB 240sx's traction is going to be your biggest problem, I can tell you this from experience. A 17x9 is the absolute minimum wheel you are going to want to run. In my opinion, the 17x10 is the minimum I would recommend.

For tire sizes, a 265 is the minimum I would recommend as it is the proper sizing for a 17x9. I have seen Silvia's in Japan with 315's, all widebody's of course, and even some of them still experience wheel spin with their high horsepower motors.

Typically, the bigger the wheel and tire, the better the car will grip off the line. I assume you are going for a drag car, so I'd say to look into the 17x10 for the S14 !

Take care!

Chris, this is where lots of my reasoning comes from. Read this thread and let me know what you think. http://www.nissaninfiniticlub....53834

Wait a sec fellas. I am about to buy rims, DT-05R's, and I was curious about rim size and offset. I want to run 255's in the rear and like 235's up front. What would be better, 17x8F & 17X9R or 18's in the same width?? What offsets would work with coilovers and Z brakes for both sizes...

[sleepyRPS13]

JIC/zeal 240sx s13 had 285s on the rear on scc mag. also ssc 300zx went 315s.. on s14 im sure 18x11 285 wouldnt be that bad but i would go with 18x9.5 or 10 though..also 275 is common for skyline gtr is bcuz they are awd. most awd cars dont go over higher then 285. also goin this big for street is unpractical but road racing.. great

vettes has wide wheels from stock 18x9.5 275/r 17x8.5 245/f and 350hp..im sure it wasnt built for drag. doh road racing of course. Im sure if you had a ka-t or sr/rb you can make that kinda power.

well bigger wheels equal bigger brakes + 350-400hp = awsome road racing car..why drag?

[Red-KAT]

I have 18x8.5 +32 front with 235-40-18's

and 18x10 +40 rear with 265-35-18's

I have no idea if coilovers will fit... I have AGX and RS*R Race springs... set to full hard...

[SoCalS14]

If you have 18X10 +40 in the rear, then a 17X9.5 +30 has to fit right? Would it stick out though?? would I have to roll?

[Ubernoober]

Just as an ancilliary to this thread...Larger tires = more grip = more broken drivetrain parts.

Don't forget to upgrade the other components as well, though I assume you already knew this.

[extheflow]

i have 18x10 in the rear @+25 with 295/35 proxes t1-s. i had to get a little crazy on the fenders with a portapower.but they fit now.

[Y So Low]

i had a s14 with 18x10.5 and it never stuck out like that. i forget the offset, but that is ridiculous the amount the wheel sticks out. it pays to get the right offset.

[extheflow]

that is the right offset. just ba crappy pic.when it's on the ground it's flush.

[240sxrb25det]

could you get some pics of it when its on the ground...also do you have the 300zx brake conversion? i think that would make a difference as to what offset to choose.

[extheflow]

i only have the 300z brakes in the front right now. i don't think the offset really matters with a 3piece wheel.i have a +42 in the front,and +25 in the rear. the spokes are the same distance from the mounting surface on both wheels.just the width of the inner and outer pieces is different. this is true for the racing hart C2's don't know if other manufacturers are the same.BTW i know my front offset is wack..i had to use a spacer to bring it out to the fender and it's an 8.5" wheel with a 245/35 on it. i'll take a pic of it sitting on the ground later on...i'm at work now.

wooh. thought u drive around looking like a monster truck with the wheels sticking out. now looking, i see positive camber which means its probably on the jack but i never need to do anything to the fender or anything. guess that's why HRE's are so good. but 18x11 nice.

here's a link that may be helpful to give you an idea about some fitment setupshttp://www.aivlis.com/tsura/data.htmload the page, then copy and paste the url into the "stanslate web page" part in altavista's website.

i didn't know they made anything that didn't fit on a vette or f-body.

[SoCalS14]

Hokiruu, I checked out that site, and I must say its nice to see some pictures of different fits, but I CAN"T read any of it!! Only the rim sizes and what appears to be spacers...not sure...
