I'd say 20 and 10, or 15 and 5. The fronts don't have near as much of that "sucked in" look in factory form, as the rears do. So to me, 15 rear and no front was ok. It's a personal preference thing, others want the fronts out as well. With 15 on the rear, the car has a muscle look to it now in my opinion. Whatever floats your boat :p

John

You have a picture of yours with just 15s?
I have seen a few on here with 15 & 5 but no one has done just 15 in the rears, you might have a winner. :D

I had 15's in front, 20's in the rear. rays wheels, stock susp. Looks perfect. Am waiting to find out how the h&r fronts work before I buy new ones.

Currently running the 20's outback. none in the front. looks good, but missing the fronts.

Not my car, but the same thing, 15mm rear only.

Vibration
 

So CptSpeed, did you ever determine what the cause of the vibration in the fronts were from? I know you are no longer running the spacers in the front, however I was thinking of putting either 5 or 10 in the front and 20 in the back. Again, I would like more info from experienced users before I make the purchase.

waiting on Mike, who had the same prob to install his H&R's. Still believe its the spacers.

well, I finally heard back from my wholesale source, and they can't get them for me, but I did actually order them elsewhere today. Will advise when they arrive.

thanks for responding. Can't wait to get those fronts on mine again.
