I don't know what size the wheels are.
They look like 14s.
I was wondering if they would fit on my '90 Integra.
My stepdad tried these on his '90 240sx and the holes were a little too big..
Would I have to go larger with bolts/nuts? brakes? etc.. etc..

 

measure them:

the wheels should have specs on the inside. if they are 4x100 then they will fit.

 

if you're referring to the mesh wheel's holes being too big for his 240sx(4x114.3) then that means the rim is prolly a 4x120 pattern or even 4x130(old Porsche/VW) but i doubt that.

if you're referring to the 240sx pattern being too big the wheel could be a 4x98, 4x100, 4x110 or 4x108.

try them on and see. only concern i see if it the mesh will clear the front brakes on your DA but I've had many 14's on my old DA's and they fit fine.

 

Okay cool. I'll check the specs asap.
Let's say it doesn't fit.. Is there any way I can change my brakes/bolts to make the wheels fit?

 

those are 14" btw according to the tire size: 185/60-14

also you could change your integra to a 4x114.3 96 itr susp but imo i don't believe those are worth changing your suspension over plus i believe that brake setup would need 15" wheel anyways..
