- - H&R Spacer ? (http://www.the370z.com/diy-section-do-yourself/126243-h-r-spacer.html)

I'm looking to add 20mm spacers front and rear. I prefer DRS rtaher than bolt-on, front and rear (I feel safer). The reviews seem to favor H&R (several complaints about vibration with Ichiba). H&R has a 20mm DRM bolt-on, #4065661, and a DRS new-lugs, #4065662. I called H&R and they say they only tested the DRM on the Z so that's what they recommend. Interestingly, the specs appear different, the Z center bore is 66.1mm, the DRM is also 66.1, the DRS is 66.2.

Is this why the DRS is not recommended? Is the extra 0.1mm enough to cause vibration?
Anyone using the 4065662 DRS successfully, or should I look at another brand?

Thanks,

I have DRS 15mm on all four corners and don't have a bad word to say about them. My vibration only comes from pad deposits on the rotors, and I suspect the only way spacers would cause this is improper installment. Make sure the rotor surface is clean and smooth before you put them on.
