so my car has a minor, but annoying, shudder at about 60mph that goes away at 70mph. This is attributed to the 5mm spacers that were needed for my OEM 18" S-line wheels to clear my front HP2 stock brake calipers.

Yes, the wheels and tires are in balance. They were road-force balanced on a Hunter not long ago. I even swapped out to my snows (which do not require spacers) and the car was fine, no shudder.

I know that the OEM 17" S-line wheels fit perfectly without spacers (I have one in my trunk as a full spare) with the same offset (ET43).

So, I am left with a decision to make...try and switch to the OEM 17" S-line wheels (I love the design of the 9-spokes), or to upgrade my brakes to something that will not require the spacers.

Any thoughts/suggestions? Anyone with OEM 17" S-lines that wants to work a trade for the 18"?

Upgrade brakes...nothing like a good upgrade!!!

I vote for brakes..but i know it won't be cheap...but are they (spacers) needed in the rear?

Ever think about getting a better set of spacers?

Of course if you like the freedom to select a wider range of wheels, then swap out the brakes.

Exactly, spacers shouldn't cause a vibration, as long as they're hubcentric.

They are hubcentric, H&R 5mm spacers.

the track of front and rear should match, so I did rear as well. Do you think it is okay to only have spacers in front???

Do you know if Stoptechs are bigger than HP2s?
