Wheel Spacers 101

Christothep

I have the 2014 sport package wheel 19x9 front 19x10 rear. Any opinions on a wheel spacer thickness what would look clean and a little more aggressive? thanks....

Not the best pic, but I recommend 20mm front and 25mm rear.

I picked up 20 and 25 spacers from corner3garage. Very nice product, no interference and they bolt right up. Even better, they are only $100 for the 2 pairs when you buy the springs. I like the end result even better than I expected.

Hey guys, I'm trying to figure out what size rear spacers I need and if my calculations are correct.

Stock rear 19" are 10et30 which is 97mm of poke from the hub.
Stock front 19" are 9et47 which is 67.3mm poke from the hub.

I am running:
Rear 20x10.5et27 which is 106.3mm poke from the hub.
Front 20x9et20 which is +93.3mm of poke from the hub.

So I am already poking out 9mm more in the rear and 27mm in the front.

Should I go with +15 in the rear or +20? I'm only at -2* camber in the rear and -1* in the front. Will be lowering the car another half inch after fenders are rolled though.

15mm spacer will make you flush with the fender and plenty of tire clearance. If you are going for "stance" look though (as you are running a stretched tire), a 20mm will work and the rim itself will poke just past the fender while your tire tucks under.

Hey guys, had some time to kill at work, so I made this that should help answer general questions.

Green cells indicate stock wheel poke.
Blue cells indicate flush at stock height.
Yellow cells indicate wheel poke for lowered Z's. Flush at -2 camber rear and -1 camber front is at the highest yellow cell for each given wheel width.
Red cells indicate wheel poke PAST the fender ON A LOWERED Z, I would not recommend any of these sizes. (unless you're going for stance and such, but this post isn't made for you).

How to figure out what size spacer you need to be flush? If you are lowered, look for yellow cells, stock height look for blue cells.

Lets use the stock wheel sizes and suspension. 10 wide et30 for the rear. Find in the chart and you see 97mm of wheel poke. Look for the highest yellow cell in the 10 width. You see is at et5 This means you can fit a 25mm spacer on the stock wheel to reach flush. Do the same for the front, 9 wide et47. To reach flush (et 25) you can use 22mm of spacers.

Would there be any issues with adding 20mm spacers in the rear and leaving the front stock? I have the stock 19 inch wheels...

Yes the back would almost be flush and the front will be battle shipped as hell. Looks wise it will look half as bad as stock lol.

These are V3 bolt-on 20mm front and rear, the car felt a little sluggish after I had them installed. However, the car did handle better and felt better, but again, they are heavy.

I know some disagree and claim they can't tell the difference, I can, especially coming out of turns. The experts claim that 1 lb added to your wheel is equivalent to adding about 20lbs to the car's total weight, the total of 8.5 lbs would be around 170lbs added to the car's total weight, sort of like riding with a passenger, which everyone would probably agree that makes a big difference.

Adding any sort of unsprung weight, or adding more rotational mass is bad for handling and control.

I guess some OZ super lightweight rims in 18 inch would be good for the unsprung weight of the Z.

I'm beginning to think bolt ons might be the way to go.
...and I'm thinking I ought to wait until I've done my drop and it's settled out before deciding on what size spacers. Bolt ons would be a snap to do.

Guys apparently im retarded and can't figure out which option i need. I want 15mm all around but i need to have the same travel length for the bolts. Can someone put a picture or tell me which option i need based on that chart from page 1? Thanks
