New 07 Yaris S need advice on 18's and springs

[OgDogg]

I just bought a Yaris S 07. I'm about to buy some 18x7.5 rims on 215/35 tires. I need to know what to do to drop it. I don't want to drop it much, and my main concern is rubbing as this is my commuter car and my friends and I are heavyweights. I was thinking of going to the dealership to get the trd lowering springs. Do I need the shocks too or will just the springs do? I really want to make sure that it doesn't rub. So I want the strongest springs that won't compress enough for the tires to rub and I'm hoping I don't need the shock absorbers. Give me some advice and let me know what's up. Thanks.

You'll probably rub on 18's with a drop... especially if you've got girth.

Either smaller rims or no drop.

[PetersRedYaris]

TRD springs give the least drop (1.2 inches) and are supposedly the stiffest. For a commuter you might want to consider 17 or 16 inch wheels.
TRD springs CAN be used with stock struts and shocks.

I have TRD 18's and TRD lowering springs and it never rubs. But if you said that u got some heavy weigth frinds I highly recomend u to go with 17's and a drop. With 17 you can go with a bigger tire because 35 rubber kinda sucks for daily driving believe me.

Still 18's look great

I can't get talked out of 18's. I'm glad to hear there's no rubbing on yours though. Do you have it on 215/35 tires or 225/40's? I think I'm going to go with just the trd springs and see how it goes. I'm about 220 pounds and honestly there's never more then 1 or 2 ppl with me in the car. So hopefully I don't have big problems with rubbing. I only use this car for freeway driving so hopefully it's not an issue. On a second though... Do you think it would still have a chance of rubbing if I bought 18x7.0 rims instead of the 18x7.5?

Trust me youll rub, I rub on my stocks when the car is full im 6 feet and 225 pounds and had the car with 4 other buddies and we rubbed on every bump

i have 18x7.5 and 215/35/18 rubber, droped on df210 springs and it rubbed slightly for the first couple of days, but now its gone, it will wear in, and i checked the fender liner and its looks fine, no holes or heavily worn out parts

if you go 18x7 it probably wont make a difference since you will still run 215/35 tires, unless you have 205 tires, but i havent seen any for 18" except for toyo t1-r

i'm not sure if weight (big guys) would make a big difference, but i still daily on 18" and drive lots of people and it hasnt been a problem, i think any lower than spring drop there will be some problems, like coil-overs low

Thanks. Hearing your situation makes me think I'll be fine with the nf210's. I'm going to wait until my rims show up to make sure I still need to drop it though.

I used 18"x7.5 42 w/ Spirit Springs 3mm spacers in the back. Only rub with 4-5 pass. (in the back right side only) *no spacers, no rubing!

I'm pretty surprized to hear that so many of you guys are running 18s on such a small car. Wouldn't smaller wheels be more beneficial with better weight reduction and a better overall setup?

yes it would be, but some people are more interested in looks than fuel economy or ride quality

18's with 215/35 tires are nearly the same size as the stock 15's on this car. Having bigger rims will just improve cornering and looks. If you get a set of racing 18's you might even improve fuel economy. I'm going to test my mpg before/after when my 18's get here next week. I'll be surprised if I lose much efficiency. The look of the car will far outweigh any minor decreases in fuel efficiency if there is any. Not to mention those of us who slap 18's on a Yaris are probably doing things to increase engine output anyway. My question is why not put 18's on a Yaris? After more carefully looking over the specs and talking with other custom Yaris owners, I sort of regret not going with 19's and no lowering kit.

my question to you is, what are you on, and why ain't you sharing?
fact (1) is a 215/35 is slightly smaller than stock, to stay exactly stock diameter you would go with a 225-30-18....

fact (2) if you have a wheel, one in an 15 inch and one in 18 inch, exact same wheel only different sizes, the 18 will weigh more, unless you did find the one wheel manifacture that makes wheel out of a substance lighter than air, then I stand corrected, added weight decreases gas mileage

fact (3) a 225-50-15 will corner better than a 225-30-18, why you ask? side wall flex.... I will explain... To keep traction on the road during a high G turn the tire needs to flex to keep the contact patch to the road. A 225-30-18 has 1.5 inches less side wall than the 225-50-15 therefore has less flex in the sidewall, therefore can not corner as fast or as sharp as one with 225-50-15

Ask anyone who truely races they will tell you the same

16's on up on a Yaris, all show, no go

[graywolf_14]

Yea see I like the trd 18's other than the fact they are 18's. If they were 16-17's that would be sweet.

I agree with most points, except the point about sidewall flex. Most track cars run a good amount of negative camber to take tire flex and body roll into consideration. An optimally tuned track car (where I assume you will carry said high G turn speeds) would also have camber set to take into account the car's roll.

Saying that we'll run a higher aspect ratio to help increase the contact patch while cornering just means that you didn't have the camber set up to take that high G bend. It would flex to accomodate the roll...... up to a point.

Then it'd flop over.

A bigger rim means a car handles more precisely because there's less tire sidewall to flex. Which means that the contact patch is better maintained.

Running a footwear size more commonly seen on Porsches and Ferraris is stupid, I must say, but on the track, there are reasons to run big rims - to accomodate big brakes such as to run big brakes.

I use 195/55/15 V-rated tires, myself. I had the choice of going to 16 inch tires for just $50 more, but decided that I did not want to lose the fuel consumption nor labour the engine with more mass to turn. I got better rubber for the rims instead.

And to the threadstarter, if you are going to have to go with engine mods to gain the performance you've lost due to upsizing to 18 inch rims, you'd be right where you started, when the car was shod with 14 or 15 inch rims. A stock Yaris might beat you off the line, though it might not look good doing it. Performing those same mods on a Yaris with a set of lightweight 15s, or even stockies, would yield a true increase in performance and fuel efficiency.

And think of the small front disc rotor and brake looking so lost within the 18 inch rim, not to mention the drum-braked rear...... do you really want to show off drum-brakes?

i use tanabe NF 210 and not rub

advice on 18's? Don't get them.

hey! since when is 220 a "heavyweight"?

I guess horse jockeys are the only normal weight folks out there.
