Hey I'm looking for some rims for my 95 240SX. 17s or 18s. Havent decided if I want the better performance of 17s or the style of 18s. What I really want is the the spokes of the rims to be as far back into the wheel as they can. So this:http://www.discounttiredirect....63683

not this:http://www.discounttiredirect....73400

See how the second one the spokes start where the rim starts and the first one the spokes are inside the rim more? Is there a name for this term and does anyone know of some rims that they have or they know of where this principle is used well. Sorry, I'm more of a performance guy than a wheel guy.

Flush faced(most fwd cars, for instance) wheels have a positive offset. Offset is the distance from centerline(the very middle of the wheel) to the wheel/hub mounting surface. A high, or positive offset has a high numerical value. Hence, the +32, +42, etc.

The higher the offset number, the closer the spokes will be to the outside edge of the wheel. Also you must consider wheels that are built in a reverse configuration(I'm not talkin wire wheels here). Allowing you to have a bit of a deep dish look, while at the same time, maintaining proper offset, allowing for a clean fitment.

There's gotta be some of this info in the FAQ...?

So what is a good offset to have on an 18" rims, while allowing room for springs or coilovers. I dont want to be too close, but i want it that "deep dish" look and i want to fill up my wheel well. I was looking at Racing Hart CR's and Konig Appeals but if anyone else has some ideas please share. Dont want to spend to much more than 1500. The rims on this Celica look so bad... http://www.importtuner.com/fea...lica/ 0 and -5 offset? Are they like that stock?

No, they are not like that stock. Notice the large polished lip. This wheel is clearly built in reverse configuration, which basically means you lay the wheel face down on the tire machine and mount the tire from the backside of the wheel. This design gives you a large outer lip for that deep dish look.

Exar has been preaching this for awhile now, so I'll continue in his footsteps: 18" wheels are heavy! They will make your car slower!

Now for what I preach: They cost more. They bend easier than 17's or 16's. Tires cost more. Tires are available in fewer sizes. Fewer shops carry as many 18's as they do 16' or 17's. They ride rougher. They attract the unwanted attention of thieves. You will consider suicide when you ruin a couple on a nasty pothole. There is a good chance they will rub. There is a good chance you will never find RacingHart 18" wheels and a set of tires for $1500. No, I take that back. I don't think you will ever find RH's in 18" with tires for $1500.

The only way you will know what fits on your car is to turn your computer off and go find a reputable tire dealer that will offer to test fit some wheels on your car.

Oh, and BTW, with $1500 burning a hole in your wallet, wouldn't you rather buy something that will improve the performance of your car? Why people place so much importance on making their vehicle a theft target is beyond me...

well said. I dont think you are taking into consideration suspension dynamics at all there CR240. WHen you run such a low offset you can push the weight centerline too far from the suspension controll arm and struts "ballance angle" (if anyone know sthe propper name for this, please inform me) causing the weight of the wheel to make the suspension function poorly and put it under extra(and un wanted) stress.

People always want a "look" or a "style" they see, why dont people work on finding things that work, are functional and then worry about the previous two items? Thats how most "styles" got started...."just because something CAN be done, doesn't mean it should."also, search.-chet

I think a good way to explain the weight/stress being applied to the steering/suspension components would be similar to a simple leverage theory. With an OEM wheel, the weight of the vehicle is placed properly in close proximity to the steering axis. The farther out you place your contact patch, the more stress is applied to the wheel bearings/steering components. I haven't even touched on unsprung weight/rolling mass/rolling resistance... all of which are evil side effects of big wheels and unnecessary fat tires(unless we're talking about a purpose built trackday car, or otherwise powerful street tool).

See also very heavy cars with reverse wire wheels. The owners have no clue as to the amount of extra stress that is being applied to the bearings/suspension, all they care about is straight pimpin. yuck.

I agree with you, Exar. Ever notice that show cars are looked at as just show cars, and we all know that the majority of them never see the highway...but performance built cars seem to have an altogether better appeal, and look even better than a "show car" that has rear drum brakes...? (notice the car in the background of the Import Tuner web page...rear drums!!)

My motto is simple: "Form follows function."

Ok I'm confused? Don't alot of the Japanese drifters/racers have the "deep dish" wheels? After pondering this question for about 17 seconds, I decided to turn to my most reliable resource.... Kazaa. Oh what would I do without you friend?? Anyway. After looking at alot of the drifting videos I've downloaded courtesy kazaa, I noticed that alot of the drifter have very big and deep wheels. Now I know this may be a noob question. But I'm a noob. Why would they, the people who probably face the biggest chance of hitting a "pothole". I mean, why would they invest so much money on these rims if there is that big of a chance to destroy them. Why not just get wider?

Japanese drifting, from what I have noticed, build monster power(something most American kids will never afford) and ALSO place a very great emphasis on appearance. Not all. Most of the well known and famous drivers do. I normally wouldn't comment on what another guy does and the reasons for it, but the limited info I have about this subject is what I've seen on various interviews of the rather famous guys.

This may not answer your question, sorry.

So you would suggest no rims? Just going straight to performcance?

worry about bigger issues than wheels beforehand, unless you just want a "show" car. I prefer evenly divying up my money between safety(brakes, chassis, rollcage, belts, etc), suspension(duh), and drivetrain/engine, I got az decnet deal on my gram lights, so I went ahead and did that after all my other work, since I cant decide on the engine route I want to take.

Start with the engine, since of all the 240's possible "in-sufficiencies" thats the biggest out-of-the-box.
