Help me decide on wheel spacer size!
 

Long story short, I'd like to keep my stock wheels on my 10 Series and space them out. I have literally seen almost every picture on the internet involving wheel spacers for this platform and can't decide. I'm down to 25 squared or 25F/30R. Which one is better? Is 30 too much in the rear? Is it necessary to stagger it? Would 25 handle better than a 30 in the rear?

I take it you are on stock suspension. I dont think you will get any benefit from going 30 in the back. They should be fairly flush with +25; at stock height you arent going to fill your arches anyway.

You can usually find sets of 20F/25R, where 25/25 or 25/30 will require you to buy individual pairs of spacers, which costs more. The only benefit to wider spacers on the rear is that the rear fenders are a touch wider than the front, so it'll look better (subjective). The handling difference between any of them and stock is minimal at best. People use spacers because they either like the look or they need to clear suspension or brake components, not to improve handling.


I have 20F/25R on my car. I could have gone 25F/30R with no issues other than cost.

Oh, forgot to add that I am on TRD springs.

Cost isn't an issue, it's only $20 more. I think I'm going to do 25/30 to fill the wheel wells better.

I'd say 25/30. As for handling... you're probably not going to notice the difference between 5mm. I would recommend extended studs if you're going to run such thick spacers.
