Are these spacers any good?

What brand/model/size tires are you running? What strut/shock/spring combo? Any other supporting suspension arms?

FIREHAWK INDY 500 Rear, 285-35-19 Front, 245-40-19 Koni Yellows, Swift lowering springs. SPL Billet Rear Camber Arms.

So, 19x9.5 +40 and 19x10.5 +23 Nismo v1 wheels with stock size rubber. Swifts drop approximately 1". You may see rare rubbing in the front if traversing uneven surfaces at speed if you go with the 15mm spacers. 20mm in the rear will be fine as you have camber arms.Ideal fix would be to get some FUCA. Alternatively, you could go with 10mm in front. Either way, I would go with type I spacers in front and type II in the rear.

Thanks for your help.

Amen to that.

I agree that whenever possible, wheels with proper specs should be sourced in order to avoid the use of spacers. However, given that v1 Nismos only come in one size, it's not like OP has a choice.

He could learn what size his own wheels are

And how spacers affect sizing

Or I could ask for help or hire a mechanic. I don’t need to know how spacers affect sizing. I only want to know which ones are good and what would work best. If you don’t care to help me, thats fine.

That knowledge would be useful to most. However, OP's history shows that he prefers to be spoon fed.

I knew I was pushing it with my questions. Useful knowledge to most but not for me. I'm close to 75 years old and chances are I will never want spacers again in my life. I may not even want them now. My wheels and tire sizes are pretty common. So is my suspension. I was hoping someone with the same who has used spacers would enlighten me with their knowledge and real time experiences. Your pics and explanations were very helpful and I thank you for that.

THE BULL

I had a somewhat shitty experience with a set.

Billet type 2 spacers, 20mm all around, measured flat, hub centric, OEM 19s

Started to develop vibrations over months, constantly checking for looseness, rotated the spacers around, balanced wheels, etc.

Upon doing rotors I noticed the surfaces of the rotors had hotspots all around the hub, rotor, wheel.

I'm leaning more towards the spacers, I believe either the studs on the spacers were cheap and stretched unevenly over time or the nature of + scrub radius excerting more weight pulls on the studs and deforms the AL over time. I have my doubts being that 20mm of billet AL should be pretty strong to prevent deformations however a stretching stud in this spacer will wreak havoc on the rotating surfaces.

It appears that my fix will require new hubs and rotors.
