I am debating between Eibach Pro Spacer
30mm Spacer / Bolt Pattern 5x114.3 / Hub Center 66.1. $101.75 Pair.

Counter Part H&R Track+ Wheel Spacers.
5/114.3 66.2 Stud 12x1.25 DRM 25mm 5065662 $ 149.95 Pair

I really want to go aggressive and put 30mm spacers, which also fit 370z according to Eibach. They are both aluminum so I am not too worried about and Eibach offers million mile warranty.

All specs match except for centric ring size. H&R is 66.2mm and Eibach is 66.1mm.

Will 1mm make big difference? Thank you for your thoughts.

 

30mm?? Now that's some cojones

I recommend going with H&R's, every race-prepped car I've seen on the track here is using them (not much of a valid reason but thought I'd throw it in)

The larger hub ring also translates to less vibration chances

 

thank you

 

Consider 25MM!!!

20s look good, 25 gets aggressive, 30 might look ghetto.

Been on H&Rs for the last 6K, no problem whatsoever.

 

goin 20mm all-around this wkend dropping on s-techs!
