Nissan 370Z Forum - View Single Post - DIY: Front Stud replacement/ Spacer install

segallis · 03-15-2018, 06:49 PM

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,
-Greg
