What size wheel spacers for stock 21s?

Just wondering what's the best size spacer for stock 21s that is aggressive enough and won't rub on the fenders? I've tried looking but couldn't find any pictures for reference. If anyone has it on their ride, can you provide pictures and what size spacers you have?

For the 2nd gen

TIA
 
I would suggest 20 front and 25 rear. I would NOT recommend the direct stud replacement type, it is a serious PITA to do the front stud replacement. 15 front and 20 rear would be in just a smidge.
 
When I had my 21's I had 15 front and 25 rear and the rear were pretty flush while the front were tucked in a little. I agree and recommend what cheste1 said above 20 front and 25 rear.
 
I am not sure what the offset specs are for the 21s but I have the 20s w/ 20mm front and 25mm rear. The fronts are pretty darn close to being flush. The rear can probably use another 5mm to be flush but with the factory width tires (narrow) it might look odd, just me speculating. I will try to get some pictures up...still trying to figure that out.
 
thanks guys. with 20mm front and 25mm rear, do i need any fender work?

probably plan on dropping with H&R springs in the future. Would there be any rubbing issue?
 
I am running 15mm spacers front/ 20mm spacers rear on my factory 21s and they are basically flush. I probably could have went another 5 on the rears to be more aggressive though because of the OEM camber. The front wheels have less OEM camber so are straight while rears have a bit of an angle. The front tires are basically right at fender if not 2mm out, while the rears are maybe .25mm behind fenders. I would do 15 F / 25R

FI you look in my pic thread there are pictures - I can try and find the specific ones that show how they sit.

here's one

as you can see, another 5mm in back would make it much better, while the fronts are just fine with 15mm.I do miss how my GTRs looked though.

These pics are also making me want to take my tail light tint off lol

yeah the 15mm front does look like it's flush. definitely don't want it to poke out more than the rear. I think you're right. 15f/25r would be better
btw, where did you buy the short stubby for your antenna?
 
The stubby antenna is a DIY mod that is on the iS site. Easy to do, vacuum tube and a 12mm fine screw if I recall.

I made it. it's a screw and a vacuum tube nipple on top. <$5 at home depot. Fine radio reception (not that I use it much)
 
The stubby antenna mod looks good but the radio reception was very poor with it especially if you are in fringe areas, I could not stand the poor reception. Go with a shark fin antenna.
 
i just got my 15mm/25mm spacers installed and they looked awesome!!
here's some a comparison of before and after
