[Gabe92RTTT]

Yeah bolt pattern is wrong. Also the offset is wrong as well.

Whats going on guys, I am in the market for some 18"x8" rims. I jus had a few questions like...what is the offset for our cars? Is there just one that will fit? If more how do they differ? Also what size tires?? I am lookin on purchasing some Falken Azenins but what size do you guys recomend? I guess Ill be using them at the track, but how will 18"x8" affect my times, I am FWD. I did a search for this but didnt find like a direct answer to my questions. If anyone has anytype of input I would really appreciate, thanks guys.

what is the offset for our cars? Is there just one that will fit? If more how do they differ?

+35mm offset is a good offset for 18x8 on our cars. Try to keep it within a few millimeters of that.

Also what size tires??

225/40R-18 is really as big as you want to go. Going larger won't help with traction at all since your overall diameter is going to be much larger than factory, making your gearing seem taller.

I guess Ill be using them at the track, but how will 18"x8" affect my times, I am FWD.

It will make you slower. Here's why:

225/40R-18 tire is 25.07 inches in overall diameter.

Stock is 205/55R-16, which is 24.88 inches in diameter.

This larger diameter than stock means your car is going to have to work harder to turn that wheel per revolution. As a FWD ( or any other vehicle ) 18 inch rims are more for show. Still want that 8 inch width? Get a 17x8 with the correct offset and 235/40R-17 tires. They will be slighter smaller in diameter to compensate for the heavier wheel and tire weight.

The reason you will run into trouble with the larger wheel is because of the extra weight from height and width increases over stock, as well as a larger tire with more reinforcements for the smaller and weaker sidewall. You ideally want a size ratio that is slightly smaller than stock to gain a mechanical advantage over the extra weight. If you are concerned only with track performance, keep the stock rims and M&S tires. Buy a pair of slicks are race rims for the track, they will be the best investment for FWD that you can do. If it is about looks, then go 18 inch.

Motegi MR-7 Gunmetal 17's with Falkens would be badass on your car.

not that i could afforde fancy rims with my plans for internal work and turbo kit... but are their 16"-17" performance rims that are actually LIGHTER and BETTER than our 2g stock eclipse rims?

 

[disturbed]

Ok im getting luminas and pro kits... but one question is.... i still have the stock rs 14 inch wheels... is this going to make a difference in anything at all? like camber or anything of that matter? im getting wheels soon just have to get the money saved up also if anyone has pics of there car lowered with rs wheels could you post them please?

 

[CowPimp]

If you lower your car, then you will need to adjust the camber. You may not have to install a camber kit, but an alignment is the bare minimum you will have to do. I have Tokico Non-Adjustables and Eibach Prokit (1.3" drop). I required a rear camber kit, but not one for the front.

 

[disturbed]

i know I will need one im just wondering if and when i get new wheels am i going to need a realighnment and stuff like that......just basically does wheel size change anything in lowering at all??

 

[Leitnin]

wheel size, being 14 inch or 17 inch should do anything, because the tire thickness (aspect ratio, the XX in yyy/XX/yy tires) should be adjusted so the tire diameter is the same. 185/70/r14s vs 235/45/17s. The only thing you would have to worry about as far as i know, is width. Some say 235 is too wide if your going to drop the car. you could probably roll the fenders but i don't know anything about that.

having 14 inches or metal wheel vs 17 inches of metal with thinner rubber shouldn't be a problem for lowering or camber. those adjustments are not wheel/tire dependent.

p.s. make sure to get a second opinion.

I'm about to get 225/50/16s for my 2GB GS Wheels. I don't race on the streets so that's not of a concern, I just want a wider tire to look more aggressive. I have my stock talon rims with 215/45 Falken Azenis on them, so whenever I want to go to the track I'll just put those on. I got a quote from Americas Tire Co they told me $425 for Falken Ziex ZE-512 in 225/50/16 (includes mounting, balancing, valve stems). I was considering Kumho MX's but they are pricey and they will wear quickly (from what I've heard).

Oh and 205/55 and 225/50 do have pretty much identical profiles. As he said above. ^^^

i am looking in upgrading my tires soon i have the 16" 5-spoke 2G rims. I thought 225 were to wide for those rims arent they only 16x6

 

[disturbed]

thank you for your imput i was thinking the same exact thing i just wanted to be sure ive never seen a lowered eclipse with the stock 14 inch wheels... so i just thought maybe it might be bad on the camber or what not.

 

[Leitnin]

well, lowering is still going to possibly need camber correction, I just don't think it will need it more severely for 14 inch wheels. The larger concern is that with the 14s, your tire is narrower, so camber problems will probably produce more undesireable events.

 

[wret]

Just get the HD camber kit and install at the same time. It only takes a few minutes if you already have the wheels off. You'll probably need to increase camber about 1.5° so figure about 3/8ths inch of spacers.

 

[wret]

225's will fit on a six inch wheel but most people agree it is not a good choice for handling considerations. Appearance benefits are debatable. I'm all for improving looks but never at the expense of performance.

Here are the details of the 205, 215, etc numbers.

225 is designed for a 8".

Not really true, and it's not this simple.

Stock 1g's are 6.5" wide, and have 205's on them.

Most 6" wide wheels will have 195's on them.

Those are for normal applications. Not performance applications. When you are running large wheels (16" and up) you have a smaller "profile" tire, so you want more "grip" with it. That is why you buy aftermarket wheels/tires, anyway, isn't it? Better traction/performance??

Most people go with the "PLUS 2" idea. An example of this is:

You have a 17x7" rim. Normally, you would buy a 205/45/R17 tire. When you are looking for more performance, you increase the width of the tire, going with one or two sizes wider. Like a 225, in this case. A 225 is designed for an 8" wide rim, but you will get better traction and cornering stability with it on a 7" wide rim as opposed to the 8" one. This is known as Plus Sizing. When you plus size tires, you put wider tires on your rims than the actual width of the rim itself.

Wrong. Plus sizing is when you increase the diameter of the wheel, and then decrease the height of the tire, so the end result is the same overall diameter.

...and here I am thinking plus sizing is for big gals.

Well it's the widest you can go, 225s are made for 6-8 inch wide wheels. I was considering 215 but there are hardly any companies that make 215/50/16s. 215/45/16s are pretty common but would mess up your speed readings according the the tire size calculator (http://www.miata.net/garage/tirecalc.html). But if you plan on getting that size for straight out performance, speed readings shouldn't be a factor. At least to me it wouldn't.

I would like to upgrade to a larger wheel size on my 95 gsx and the wheel well looks like its plenty large enough to accept a larger wheel, yet when i put my hand underneath to feel around it seems there is this cross bar going from the top of the wheel well to the suspension or something. I have no idea what it is but i know its about a half inch away from touching my wheel already. my question is do i have to remove this or do something else to put bigger wheels on?

 

[Maximum404]

I believe that you can get up to a 18x8.5" on there assuming that you havent lowerd the car at all. If you suspension is stock, go to www.tirerack.com, just enter your car in and they will show you the availalbe sizes/types.

Someone correct me if I am wrong.

Hope that helps.

I know what your talking about and i wonder the same thing. but i thought i read that 19's can fit in the wheel well. im not positive, but i thought i read that. but i think 19 is a little overboard if you ask me

You could fit 22” wheels in there; the problem is the rubber part. The limiting factor (on a 2g anyway) is control arm that passes over the tire in the rear. A different tire that is either taller or wider could potentially rub on the control arm. This is why you need to carefully consider tire size and wheel offset before you upgrade.

Typically most people use a calculator like this one http://www.miata.net/garage/tirecalc.html to keep the overall diameter close to stock. This limits the chance of rubbing, speedometer error, and incorrect gear ratios.

Hm. Today's wheel size day, I see. Odd how this sort of stuff goes on.

[BoBbOrAzE]

hey thanks this helps, yea i think thewheels i have now are about as big as i can get without rubbing the control arm yet there is so much more room in the wheel well for bigger wheels, i have seen other dsms with larger wheels on gsxs, is it because they have removed this control arm?
