The ichiba's came today (labor day) 10mm spacers for each side in the front. I put them on and went for a drive to see if it solved the vibration, which it did. With the wider track and Michelin Pilot Sport Cups, I feel the car more sensitive to the road. The car would rather be turning than going straight, or so it seems. They also feel softer while turning, like the sidewall is not as stiff. I'm not pushing them for a while as per tire racks instructions so I can't give a thorough review. I'm sure the 5 mm H&R's can work but since my rims come off regularly for brake bleeding and inspection I didn't want to fool with them. They are hub centric but don't have a centering ring on the outside. Now I'm waiting for my tire pyrometer to arrive. I want to keep these tires in their "happy place" and have them last a while longer than the PS2's.
