Will this fit? (width, offset and tire size Qs)

[Leonardo]

If you are asking about optimum driving and don't know very much about wheels and tires. Going staggered is not a good idea.


Get four of the same wheel and tire. You can rotate all your tires this way.


I'd suggest the 18x8.5 with a 225/40/18 tire.


Camber is caused by lowering your car. (or by installing parts that change camber) A few degrees of negative camber is good for front grip and won't cause uneven tire wear if your car is aligned properly.


Good Luck!

Thank you! Performance wise is there much difference between 17 and 18 inches?

17's are for performance. And 18's are for looks. Generally speaking.


Will you notice the difference on the street? Probably not. But some guys are very sensitive and will rave about the difference in feel for lightweight wheels.

If the screen shot is accurate, then the 18x8.5 Enkei is the same weight (21lbs vs 20.6lbs) as a stock wheel.


If you are thinking about getting lightweight wheels, the Enkei RPF1 is a great option. It is lightweight, strong, around $1K for a set, and IMO, is not that bad looking.

Sorry again. So I’ve narrowed it down to your suggestion of 18x8, 17x9 and 17x8... I think that I’m leaning towards 17x9

If you are considering 17x9 and stock suspension (or lowering springs), get +35 offset. If you have (or are getting) coils; then a higher offset will work too.

i have 18x8 raijins +48mm offset all around, lowered almost an inch on eibach pro springs. it looks close to flush in the front, but a little sunken in the back.

According to the fitment chart, it is 8-10mm off from flush in the front and 16-18mm off from flush in the rear.

I'd rather avoid spacers in the front because i don't want to mess too much with the turn in and scrub radius. I do autocross the car regularly and do spirited driving frequently and would rather not screw things up, particularly since i like the fitment up front even if it is not perfect. I do want to bring up the rears.

- its fine to run spacers just in the rear right? I understand this result in slightly biasing the car towards understeer by adding a small amount of grip in the back, but i can't see any other downsides

- should i keep the distance the same with the front (i.e. an 8-10mm spacer on the rear so both sets are 8-10mm from flush) or just try to get the rear wheels as flush as possible with a 15-18mm spacer? will going with an aggressive rear spacer cause any performance problems against the stock front axle?

I have eibach prokit springs and 18x8 +45 front wheels. Very similar to your setup. I have added 1" front spacers to mine. I posted pics in this thread... I have -2 natural rear camber from the springs. And, -1.4 front camber from a set of camber bolts. (not even maxed out)

I would suggest: if your are going to put some spacers on the back, put the correct corresponding size on the front too. Purely for the fact that the wheels will stick out the same amount which IMO looks good.


This is a good offset tool.

You are thinking of adding 15-18mm to the rear. Good, that is right at what will be flush IMO. I would add a 20mm rear and a 25mm front. Or for a slightly more conservative look: 15mm rear and a 20mm front.

If you add a 25mm spacer in the front your front wheels will poke the same amount as a 9"+35 wheel, which is a very popular width and offset.

What size tire are you running?


Stock Front Track Width
1,520 mm (60 in)

Stock Rear Track Width
1,640 mm (65 in)

The wheels won’t be all slanted right? And another question what kind of tire size would be optimal for the 17x9. Im about to buy the hks coilovers along with the enemies rpf1s 17x9

Thanks man. I am running 225/40/18s. i might upsize to 235/40/18 but i am not set on it.

i am trying to figure out why i would need a front spacer if i am happy with the semi-flushness of the front wheels. spacers on the back only might poke the back would be to try to get it to around the same level of poke as the front, right? provided they are the right size at least. If i add even equal spacers (like 2 sets of 20mm) then the front will still poke more than the back, which is not what i want. i want them to either be square or have the rear poke more, since this will widen the track without affecting the steering wheels. Spacers on the back will also give the car some of the look of a staggered setup, while allowing you to retain handling balance closer to neutral. Again this is just my understanding of it.

Lowering a car will add camber. Some camber is good for grip. Optimal size for DD, IMO, 225/45/17.

To have the top of the tire tuck under your fender, You'll want more camber the lower the offset your wheels are.

Are you installing the coils yourself, because there is a great DIY in that section. I followed the DIY, and it only took a couple hours.

If you are happy with how it looks, then none are needed.

Going wider than 225 for an 8" front wheel will kill some of the steering preciseness.

The rear track width is 5" wider than the front stock.

You can run as much offset as +42 with 17x9 and stock-diameter springs as long as you don't use camber bolts. I'm on 17x9 +40 with Swift BRZ Sport springs and camber plates:

Ok last question I swear. Im thinking of getting work emotion kiwami and i would like 18s. should i run a square setup or staggered? Also im trying to go for more of an aggressive look so what specs are best for either square or staggered. Thank you guys for all your help!
