Sooooo H&R spacers, anyone messed with them? **Update: Need to decide tomorrow!
 

Probably not going to go with coilovers on the car but spacers might look nice. Recommendations? I don't want wheels protruding any further than the fenders but I'm interested in what people do with front/back on the nismo car.

I can tell you, ichiba and H&R are the exact same. I have H&R on my rear tires and ichiba on my front wheels. You are really paying for the name, they are all made out of the exact same material. Go to FB Nissan on here (jomer) and he can hook you up with a really good price.

Size recommendations?

I don't have a nismo but with my stock 19" rays and sport package I went with 20mm all four corners. This ends up with the very outer edge of the tire exactly flush with the face of the body. These are h & r with no drop. At first I thought it may not be enough but 3/4" has more of an effect looks wise than you would expect.
I went we with h & r stud replacement based mostly on recommendations on here and because there was a local distributor with stock.

Thinking this will be my next project since the RC brake vents are cost prohibitive

I went with 20mm all around as well on my sport package rays. I went with the bolt-on ones, took me 10 minutes to put on. The stud replacement ones are cheaper but are more time consuming to install.

I think the ones with the stud replacements would make me feel more at ease.

Thats what I thought too, but the H&R I went with initially in the front, the studs that came with them were of lower quality than the stock studs, at least to me they were.

I agree and the first one took me about 45 minutes to do but after that I had the details down and did the rest in 20 minutes each. I didn't like the idea of lug nuts hidden behind the wheel where they can't be checked easily. I've checked the torque on mine several times after install and it hasn't changed. Just my .02. :tiphat:

I tossed around 20mm all around and checked out other members with that setup. Ultimately 20/25mm was the perfect setup for me i looovvveee the look with the coils. Z1Motorsports spacers though and no complaints.

I think the spacers' material is comparable across the H&R and ICHIBA brands, but not the type of spacers.

The DRS H&R are safer, and the same type is also offered by ICHIBA, but they're not as prevelent for some reason.

From what I've gathered from other people, I would install DRS spacers (with replacement studs) in the front, and DRM (studs built into spacers) in the rear.

Go 25mm rear and 20mm front with built in studs. I have that setup on my car. Works super well with me dropped on swifts. I used DRM all around. Not sure why everyone recommends DRS. I got 11 full cycle turns on my lugs...recommended is 8 turns.

For what its worth from a newbie to spacers I had ichiba 10mm drs and had a nasty vibration. I switched to 15mm H&R and now it runs smooth. I got mine from Charles @ b2autodesigns a forum sponsor and it was a simple process. There are some threads on here too that helped me solve the problem and lead to switching to H&R.

Thanks for all the input folks. This will be my spring project. I had to promise the gf that I'd stop screwing with the car for ~a time~ after my exhaust and cats go on next week.

OMG! , Did you really just say Ichiba and H&R are the same??

H&R made in Germany! Ichiba is made in China!!! I would never put anything on my car made in China.

I have DRM H&R 20MM all around smooth as butter!
