not any that i know of yet. i believe if i take a corner really hard the fronts rub, but that'e because im running a 235 up front.

if you want to go for relatively the same look, get 25mm up front, or 20mm if you dont want to pull the fenders.

Sorry, they weren't comfortable mounting the wheels back on with the spacers because after the alignment, the tires were going to be about 2mm past the fender. I was expecting it to have 1-2mm clearance but getting my camber into spec really pulled the top of the tire out more than I expected. With how low my car is, I would have had fender damage if they hadn't been careful and noticed before setting it all the way back on the ground. Luckily, they noticed while lowering the lift, raised it back up, and took off the spacers.

I ended up having to drive home without spacers and then buy new spacers for the correct fit. I'll have to do this experiment the next time that I get new tires.

Yup. Time to throw away the training wheels and venture out into the big-boy forum.

Jason thanks for this thread write up. Most informative and i am positive much more informative than what we could find at our local shop for our vehicle. I hope calling noobs reatards for not searching is over with. If you dont have the answer to contribute then dont respond. You are the man for doing this write up- if i had not searched then i would have bought the ebay 15MM on my stock set up. Now i know i can go 20-25 and a fender roll if need be which i had no clue that could be done. Keep contributing that knowledge!

19x10 -1 265 35 19

Nice Duckeee, Here's another shot of mine. New paint and new kit installed.

Default Caveats of wheel spacers

Just info that I found that's *out there* on using spacers. I'm doing my DD and I'm thinking of adding 15MM spacers F/R on my stock rims (08). This info is what convinced me to keep conservative on their use for stock rims.
Can't post the link here..it's another forum.
No flames please..I'm just the *messenger*

How evil are wheel spacers?

From Skylines Australia:


Quote:
This moves the tyre contact patch outwards, which means;

Tramlining, pretty bad I would say
Premature wheel bearing wear
Heavy steering
Hence steering linkage wear
And steering rack wear
Premature tyre wear
Increased loading on the radius rods due to the increased leverage
Leading to increase radius rod bush wear
Or if you have spherical bearings with adjustable radius rods, perhaps bearing failure
Premature wear of the upper inner and outer conrol arm bushes
Premature wear of the lower inner control arm bush
Premature wear of the lower outer ball joint

That's about it for a start.

Sydneykid is pretty knowledgable when it comes to car setup. He was referring to someone looking for a 30mm spacer, which is pretty big. Most people get away with 5-10mm spacers.


Another telling post:

Lowering the offset also widens the track. And its the widened track that changes the leverage points on the hub / suspension to cause those issues.

Spacing out a narrow wheel is, effectively, a lot worse than running a wide rim for looks because it does increase the track so much more to get it to line up against the fender in the same way.

For example, lets take the 10.5 +22 width and offset that's popular for the Z. This sits flush against the fender. Your track only increases 16mm. Now if you take the stock 8.0 +30 rim and get it to sit the same distance away from the fender, you'd have to run a 32mm spacer (allow a certain error margin as the design of certain rims makes the perfect fitment different for certain widths and offsets). That means your effective track just increased 64mm.

If you look down the flank of the car, dish or concavity aside, both rims sit almost exactly the same way, but one of them is destroying your suspension far faster than the other.

I have 25mm Ichiba's on my stock 18's at stock ride height.

Any ideas on how can I prevent some of this stuff?

As you can see, it's not a matter of rubbing with stock height...it's the stress with wider offset.
You may be OK, but the greater the *effective offset* (which spacers increase more than wider wheels), the greater the stress..especially up front.
You can simply wait it out and see what happens..worst case the wheel bearings and/or steering rack show wear and tear. I would avoid 25s up front on stock rims....so if you want to play it safe, switch to 15 up front.
