Thinking about buying some wheels spacers after I drop a suspension kit in my tC2. Any recommendations? I'm planning on keeping the stock wheels for now. Thanks!

 

15mm ichiba to flush the fronts and 25's to flush the rears

that is on dropped car...

 

I think this was the link someone gave in another thread (might have been scion202) http://www.phantasmusa.com/ws5511460c.html

 

I'll look into that thanks!

 

go to fastscions.com and select the spacers for XB2, it will show u the part number then just ebay with that!

 

Scion202 got a pretty sweet setup man. Thanks for the info too!

 

Do not use any wheel spacers at all!

 

@ 2tCornot2tC may I ask why? Please explain.

 

Some people do not like wheel spacers because back in the day they were very dangerous to use. Alot of sheared studs or wheels separating from the vehicle. I have used wheel spacers before on a truck that I would take off road and had zero issues. They just need to be the proper type for your vehicle. I think the ones our cars use are hub centric. I will say use at your own risk and ensure they are properly installed and set to the proper torque specs.

 

from engineering stand point its an absolute NO-NO

pros:
looks cool
wider stance

cons:
increased unsprung weight
increased complexity of a moving part
increased turning radius
increased force on the ball baring

 

Discussed at length here…

Where is my math/reasoning wrong?

7.5 inch wheel = 19.05 cm
center line = 9.525 cm
with offset of 39; 5.625 cm of wheel extend out from the hub and 13.424cm goes towards the car.

SO:

5.625/19.05 *100 = 29.528% of the wheel width extends out from the hub. So in order to keep all the forces equal, wouldn't you want that ratio to stay the same???

yours now:

9" = 22.86
center line: 11.43cm
with offset of 40; 7.43cm extends out from the hub

so 7.43/22.86 *100 = 32.502% extends out from the hub

 

You are correct…but, the performance/handling of your vehicle and the loads that go through your suspension all go through the centerline (weather it is a tire, wheel or suspension component) therefore the “ET” is the most critical measurement on a wheel. The amount of wheel inside the mounting face is a reference for suspension and wheel well clearances and the amount of wheel outside of the mounting face is a reference for fender clearance. Yes, you have to check those clearances, but you design to the centerline. Unless you are capable of making some very major changes to the suspension design, do not change the “ET” of the wheel...a wheel spacer does that.

Check here https://www.scionlife.com/forums/sho...d.php?t=206561 to see what pivot radius is in the sketch of post #8...that, you wnat to keep at zero.

 

so then which offset would hurt the suspension geometry and ball baring loading the most? going above 39 or below 39? or its the same?

 

Hard to say without having the complete design…it’s like asking, would placing the crowbar on the inside be worse or using the crowbar on the outside be worse. You are still using a crowbar. Spacing the wheels (offset) is the crowbar…small (short), but your loads are large (weight of the car).

 

 

Is that an aerial shot of the Arizona in Pearl Harbor?
Why did you post it here? Nice shot…but it doesn’t make sence…

 

Is that what will happen if you install wheel spacers? I'm outta this thread then

 

Thats what happens when you dont install spacers... sunken battleships...

 

dont mean to highjack this tread but i didnt want to start a whole other one just for this question lol ... i am on trd springs and trd 19 inch wheels and am going to buy spacers soon i will be getting 15 mm bolt on for the front and 22 mm for the rear .. will i have to shave down the oem studs ???!!!! or
