how wide rear tires is every one running on there KA-T ???

[projectka-t]

(1) i know offset has alot to do with it but i was currious how wide everyone is running? and with what results? the reason im asking is i have run into a vendor that has some 17X11 wheels 5 Lug and i would love to go that wide in the rear but didnt know if this was feasible ?

ok and i have another question

(2) has anyone used the wide body kit from enjukuracing.com - Versionselect ? im planning on ordering a kit from there soon and would really like to have the wide fender kit but wanted some feed back fro you guy!

11 inches is WAAY too big for the rears on a 240sx. I dont think you have a concept of how big those wheels actually are, because if you did you wouldn't even be asking.

I am probably going to go with a 17x9 in the rear, most likely with a 275/40/17 tire. Fronts will be 8".

[:: orion ::]

17X11 is uneeded IMO...a 10" rear would be *perfect* for me, with 275s.

(In fact, my next set of wheels/tires will be 9" fronts with 255s, and 10" rear with 275...not for drag...for road course)

Anyway, right now I'm running Kumho MX's (255/40-17) in the rear on a 17X9...and I get a little wheelspin in 2nd if I lay into it...at ~300rwhp.

If I powershift from 1st...it'll spin to redline...but a normal quick-shift will just spin for a second, then hook and go.

Right now I'm running an 18x10 with 265's... You could fit an 17x11 if you role the inner lip of the fenders. My wheel sits 1/2 inch away from it with some mean camber. As soon as I get rear upper arms I could take of the spacers... But with 10ich and camber my wheels hit my rear shocks on bumps. (without spacers)

[Structure240sx]

i run 17x9 +43 offset 0 camber and nitto555r II (raod race version) 275/40/17

once these tires have a little heat on them they hold 350rwhp great. launching i can break them loose but from a roll they are awesome. i dont have any pic of my car with them yet online, next week i will once it done getting painted

btw i have the lips of the fenders rolled in (used a hammer carefully). i did this when i had coilovers and the car was slammed, might not be needed now.

i would also like to go with some 11" wheels in the right offset and get some 315's maybe

if i didnt have to get my car painted last minute for sema i prolly would have gotten the overfenders like you are talking about also.

someone school me on tires. why or how does a wider tire give better straight line traction?

Wider tires = Larger contact area = more traction

Structure - 315s on a KA-T Coupe =

[nismofly]

wider tires doesnt necessarily mean larger contact area...go visit wheels/tires

[virus77]

I run 9" in the back with falken 275's. At around 300 whp they give a nice chirp, maybe some wheelspin with a lsd. At around the 350whp point on a 1-2 shift they would spin til redline.

[Structure240sx]

area is lengthxwidth. so if you go with a wider and taller tire that is even more area put on the ground.

tire size is not the only thing to look at. notice how i said the nitto 555r are holding 350rwhp for me. yet in the same size virus can spin his til redline.

the nitto's have a 100 treadwear rating and also start with 6/32" tread compared to normal tires 10/32". this is why they are considered drag radials. they are not full drag radials which normally have a 0 treadwear and do not last as long

the nitto's are advertised to last 10-15k miles and i have no doubt that they will not live up to that. its been two months and abot 3000mi. and they are doing great.

[Structure240sx]

heres a shot from 2 days ago as i was doing bodywork to my car before i dropped it off for paint, as you can see they sit pretty flush with the setup i described previously

[MarkEmark]

I have 16" x 8" + 10 mm offset wheels, 245/45/16 Yokohoma AVS sport tires out back...I have no traction problems at ~9 psi from a T3 super 60, except maybe in first gear depending on how I drive it...I also have an LSD though, and they're expensive, sticky tires.

17x8 +30 with a 245 bridgestone potenza so3.

[Red-KAT]

My one wheel wonder broke a tire loose in 3rd gear. Went from feel fast to wheres the power? I like my Sumitomo's. Cheap and somewhat sticky... If I rost the back tires off its $200 to replace them.

[Structure240sx]

get the wide fenders. i might later one when i get bored. should be able to paint them and rivet them on so i wont have to worry about painting the whole thing again or maybe just some flares

[rn240sx]

I run 17x10 in the rear with 285x45x17's...

If u need i can get some close ups on how they stick out of the fender...

I would love to see some pic's i was thinking about the 17X10's and i just didnt know about the 11's and just wanted to ask, Thanks every one for the input

im about to order the versionselect body kit and just do not want any rivets showing on the overfenders and quarter panels and can not find any pic's of the finished product! I just thought with 30MM extra on the rear she would look bad as snot with a set off 17X10 or 11 wide.

area is lengthxwidth. so if you go with a wider and taller tire that is even more area put on the ground.

thats not true; the car rides on air. at the same tire pressure the contact patch will be the same area but a different shape for different size tires . with a wider tire the pattern is short and wide, good for lateral grip/handling, and with a narrower tire its longer but narrow, not sure theres any adantages there except ride quality. the wider tire will of course wear slower, but how does it make for more traction?

and btw, do any of you guys use bfg dr's. imo, nitto's suck, g-force t/a is the stickiest radial tire i've used.

[Structure240sx]

you even quoted me saying "wider and taller"

stock 205/55/16 iirc are about 24" tall, my 275/40/17 are 26" tall, this would put more area on the ground along with the stickier compound

i have a set of bfg's for the track in a 235/60/15, seem to hold well off the line. without much practice i cut a couple 1.9 60's but was having wheel hop issues that will be getting resolved. the nitto's i use as a street tire

[DRIFTEADOR]

sorry, i meant to quote titanium but thats still doesnt explain more traction. you have more tire, but still the same area touching the groung at one time.

[Colorado_S14]

I run a 17x8 +25 with a 235/45-17 in the front and a 17x9 +35 with a 255/40-17 out back. I am getting a 17x10, 17x9 stagger next with the same tires.

This guy is the win. A contact patch, according to Skip Barber Racing School, "has the approximate area of a postage card. When using a wider tire, the length increases, but width decreases." As he said, it makes more lateral grip. Which means more straight line traction. But.. it also gives more surface area exposed to the air to cool down the tires, making them hard to heat up and keep heated. There is a tire too large for an application.Nittos are good tires imo. I had NT555s, not bad at all for street.

I run a 18x10" in the rear with Goodyear Eagle F1 GS Fioranos (whew.. mouthfull) in 265/40/18. My nittos were 35 series and were 1.6% larger than stock.. these new ones are ~6% larger.. but $200 for the brand new pair of $700 tires. 18x8" up front with 225/40/18 Nitto NT555s. Haven't used drag radials in ~6 years, so I'm way behind the times with the new ones.-Jeff

[TurboKA37]

correct, changing tire size (in theory) will not change the area of contact patch unless weight or tire pressure is changed. although running larger tires can help straight line traction. changing to a taller tire is like making the car's final drive longer therefore more tire revolutions per RPM which makes it harder for the engine to break the tires loose when accelerating. Im sure a lot of you already know this stuff but its good for those reading through that dont. good thing you didnt post this in the tire/suspension forum tho, they would probly take your balls and lock the thread

i run 245/50/16 on the rear on my stock alloy rims. they have this 'chubby' look to them on stock rims s14 rims. the tire is about 10 inches wide..

[S14tat]

well from what my professor told me ( he races pro stock ) he said that the main reason why you get more traction with a wider wheel is beucase there is more surface for the rubber to sheer against the ground. he made an example with a box of chalk.

he put a scale with hook to the box of chalk sitting vertical. this would make the surface area that is touching the table appear to be narrow like [] when he pulled on it, the lb. in. it requires to pull is the exact same as it was when the box of chalk was laying flat [ ] like that. this is becusae no matter how you put it, it will have the same amount of weight on that surface area becasue the chalk box is not gettin lighter in anyway. however if that area is made of rubber, then there is more rubber to resist sheering off the line with alot power compared to a skinny tire.

not sure how true this, but when he did the demonstration and did some equations it seemed to make sense.

Holy crap, that might work for dragging, but I wouldn't want to turn hard on those, they must roll like the pillsbury doughboy!

Markemark... where did you get your wheels and what is the specific model and size. i really like them wheels!

[MarkEmark]

They are more or less one-off, custom bogart racing wheels (www.bogartracingwheels.com), 2 piece forged with spun shells, 16" x 8", +10 mm offset rear, 16" x 8" + 16 mm offset front.

225 tires in the front, 245 tires out back.

Unfortunately, the fender lip needs to be rolled out back....not a big deal, but the car is already pretty low and I need that extra clearance. Probably wouldn't have had the problem if I went with 225's all around, but I like the meaty look in the rear.

[chad_KAT]

eh. im having some trouble finding them. does anyone else here know who make simular looking wheels?
