New rims on stock tires?
 

i was interested in getting the work emotion kiwami wheels in size
17x7.0 / 5x100 / Offset +47

is that okay? nothing wrong with that right? because i see a lot of people with bigger tires and rims...

why do people have different tire sizes for the front and back of the car?

Why? Might as well keep your stocks... If you spending the cash to buy wheels get something more aggressive.




But yes those are basically identical to stock.

stock = 17x7 48 offset

at least get some 17x8 45 offset so your flusher <- stock tires will be stretched on that. I ran stocks on 17x8 for a while before upgrading to some real tires... 235/45/17. Soon going to change the fronts to 235/40/17 and rear to 240/40/17

Well, there's nothing "wrong" with that. That's almost identical to the stock wheel size (17x7 +48, IIRC) so it will be very similar to the OEM look and performance. The "problem" is, well, the same thing: the OEM wheels are narrow and the OEM tires are scrawny, which is the main reason you'd want to upgrade to something else.

People put on bigger wheels and tires for two main reasons: style and performance (aka form and function). Some people go for a balance of the two, some people lean toward one or the other.

On this car, different (staggered) F/R wheel or tire sizes are typically for the "style" side of the equation. The 86 is very well balanced, and so far I haven't seen any evidence that anything but a square (same size at all corners) wheel/tire size is optimum for performance.

why do you want to do that?

Because someone might want to keep the same low friction tyres and save weight at the same time. With a bonus of having better looking wheels.

Quite simple actually.

I went with a similar solution (17x7 +42) but junked my Primacys and went to stickier rubber in 215 size.

I wanted to preserve as much of the tail-out fun of the stock car as possible, but gain a little bit more grip - especially in the wet. I've got better looking, lighter wheels now, too.

i asked him because i wanted to know his reasoning, not to be an ass. its not simple at all really. if you want to have light wheels to improve gas mileage, that is stupid. why spend over a thousand dollars to save a couple cents at the pump? if you want to save weight to go faster, you are only going to be dissapointed because wheel weight is borderline insignificant while spending half the money on tires will shave seconds of any qualitative test you can throw at the car. if it is to look cool, thats fine (unless youre trying to impress someone who feels that going fast looks cooler than looking fast). again, i only asked so that the op might receive a more informed response and can make a decision more suited to his goals.

Reducing unsprung mass really improves the ride quality...Aftermarket wheels dimensioned like stock but that weigh 3 lbs less than stock give a very noticeable improvement in ride quality with the stock tires and suspension. The main reason for reducing wheel weight should be to reduce unsprung weight for improving ride quality by letting the stock suspension work more efficiently and with less wear rate.

if you plan on spending close to $2000 dollars for the sake of ride quality, there are better places to start than rims. i dont know if wear rate is too valid considering that you end up spending more than you would save. i guess its just me thinking that the only real reason to do this would be because you think it looks cool.

I'd agree that spending ~$2k on wheels mainly for ride quality is overdoing it, because for a little over $2k you would get much better results with the Essex Sprint AP racing brake system (20lb reduction from stock) while improving braking at the same time. However, dropping ~3.5lbs from stock mass for less than $800 total for a new set of Enkei Fujin's as the daily wheels is really reasonable (especially when you sell the stock wheels)...plus the car looks nicer as well:

And by wear rate I meant wear rate of the suspension components, meaning the stock shocks last longer and a little less wear/tear on bushings etc... for a given mileage.

Does anyone have good pix of OEM 215/45 tires on 17x8 wheels? off the car? I'd like to see the stretch. I'm weighing options, and upgrading rims now, tires later is one route.

they're not the oem ones but they're the same size on 17x8. It's stretched a little bit but nothing ridiculous.

this is mine on 17x8.25 stock Michelins ...

^^^That looks awesome man.
