H&R springs, Spacers, Rear Camber Arms installed
 

First off i just wanted to thank JOSH @ Stillen for getting me a GREAT combo deal on the H&R Sport Springs, H&R 15mm/20mm spacers, and Eibach rear camber arms and toe bolts. Not only did i get a great package deal, the parts came within LESS THAN A WEEK. Thank you once again Josh.

I don't have artsy pictures and stuff as im posting this thread to answer the questions that i have been searching for in other threads, hopefully this will sway you towards buying this set-up or not.

This is how low the drop is on the H&R Sport Springs on a 2010 Sport Package 370z. This is on the first day of install. The drop is 1.3 inches in the front and about 1 inch in the rear (according to H&R) It will settle lower.

various shots of how much gap there is, (this is less than 24 hours of install so expect it to go lower).

This is the whole setup of the above parts with the alignment done.

Common Questions.

Will i scrape?
yes you will, this drop will force you to take speed bumps and other things at an angle. You will hit the chin spoiler, i would imagine the guards in front of the front tires will scrape quite a bit, so i had the tech removed them. You will need too with this drop.

Rubbing issues with spacers?
no rubbing issues so far as far as spacers are concerned, i was going to do 20mm all around but read that people do have rubbing issues in front with the 20mm spacers.

Handling characteristics?
i can't really answer this as the car underwent the transformation at about 80 miles on the odometer. I will say this, the steering is not as "floaty" and the car does seem more planted. When the break-in period is over, i will add more.

Do I need the Toe bolt holes enlarged?
After the tech. installed them i was told that i could have gotten away and pulled the stock alighnment settings WITHOUT him having enlarged the toe bolts. I personally am glad it was done, eventually when swapping rims or when i switch to coilovers this will have to be done, so why not do it now.

Overall impression.
Coming from having many lowered vehicles i prefer my cars to be lower and couldn't stand the stock height personally. This combo aesthetically is more pleasing to me and personally i hope it settles a little lower. This is a good way to go if you are on a budget and you want a more aggressive stance. The ride quality is OEM, that is definitely a plus. You will NOT experience the aggressiveness of stiff coilovers with this set-up. The spacers compliment the drop very well and i would not go any higher than the 15/20 mm combo if you are new to this modding business.

for those local to the area of Washington, Axiom Motorsports in Lakewood did the install and alighnment. The Tech was Brandon, see him if you are getting things installed.

hope this helps, just want to do my part and contribute to a forum that has helped me.

*****update***** springs have settled and i believe it is as low it will go, which is one finger gap in front, and 2 finger gap in the rear (or 1 1/2 for you with large hands) Springs are like OEM, no complaints, however if you want to go low and have fairly decent roads, i would go with coilovers, i love these springs as they are just like OEM and ride great but there still is a noticeable gap in the rear that bothers me.

Wow Looks Great and adding the spacers made it a total package. Great job.

Looking good. I don't have the toe kit installed. I haven't scraped my lip yet even when driving in downtown Seattle and their tight parking garages with steep ramps. i prefer 20mm up front because that's closer to flush, although 25 would make it really flush. The only time the wheels rub against the plastic nob is on the highway if there is a big bump or dip. only happens at about 3 or 4 spots on the entire I5 around from renton to lynnwood. I've never rubbed driving off the highway. You're going to have to get an exhaust now. Coming from a 350z I was surprised how quiet the 370z exhaust is.

Looks great! Love the red, BTW.

So why did you go with Eibach rear camber arms instead of SPC? I want to get coilovers and therefore will need rear camber arms, so just starting my research now.

Thanks guys, I tell people that they will scrape because a majority of people here don't have as good roads as we do in Washington, so they wont be surprised when they do scrape. Your right our exhausts are stealth lol! Eibach rear camber arms are manufactured by spc, same things pretty much, just a difference in price.

very nice man! Will get the H&R in a few months!

Axiom motorsports? Ima hav to try der....for my installs I went to arsenal motorsports in everett. Nice setup btw... one question, so is it possible to put 25mm spacers all around?? Will der be issues? I really want to drop mine....but springs are still too soft for my taste. I prefer coilovers, but those can be pricey...

Does anybody want to go acutint of seattle to get the di noc carbon roof done? I'm going to get it done end of this month... more cars, more discounts

nice! we have the same color and setup! While driving at slow speeds do u hear any noises from the suspension? I hear squeaky noises all the time so i might take mine back

On springs, 20 mm with slight rubbing in front, 25 mm in the rear will stick out pass the fender wells, however negative camber can fix that. No noises so far.

looks good i think ill have to lower mine , i lowered my lexus and it rides awsome

Looks great!!!

to the OP > If the rear gap bothers you, you can always remove the OEM lower rubber seat/mount to bring the rear springs closer to 1.3" like the fronts. I did that with my H&Rs and it looks much more balanced and there is no noise from the removal of the rubber seat either.

thank you, i think i will do that, any negative effects of doing this/ future issues? thanks!

No you didn't! :p

I left mine in because I figured that metal against metal = wear. At least I'm thinking that is what that hard rubber mount is there for, if not the engineers won't put it in there...

Just my thoughts.

true, i will just leave it in and get coilovers down the line, thanks guys.

Looks very nice, man!

You can also do the springmount mod, cutting it down. There is a diy on the 350z forum. I prefer having more wheel gap in the rear, gives it a more agressive look.

Yeah I also think that the car being level does not look as good. You want it higher in the rear; gives it a meaner stance. Plus if you have to put something heavy in the hatch, it can handle it. (or a fat gf) lol

sorry guys this ride gets no fat chix! ya dig!

lots of washington members popping up. it may be meeet time again

yeapppp

Lo0ks great bro! h0w much did you pay for the install?

between $400-450 if i recall correctly.

I looked on H&R's website and they don't list the wheel spacers. How much were they? did they require different lug nuts for the stock Sport Package wheels on the 370? Do you have part numbers or know a place I can call to purchase the wheel spacers? Lastly, you said 15 mm front does not rub, any issues since installing?

Thanks in advance for your answers!

Are the camber arms required on the rear to get the car back to factory alignment? I was going to have the springs and +15 spacer front and +20 spacer rear.

Can the factory alignment be reached without the control arms front/rear? If not, what is absolutely needed?

Get the spacers that have longer replacement studs (DRS). That is a requirement for the front...the other ones (DRM) will not work up front. You will NOT need different lug nuts.

Spacers will add more negative camber and therefore take it further out of spec. You will need camber kits front and back to adjust back to within normal spec. Our stock front upper control mount has no adjustment for camber or caster at all.

Yea, I have the front upper control arms for my 350Z and that made a difference for sure.

So what you are saying is I will need adjustable arms for the front and rear of the car to get the tires to wear properly if I decide to do spacers and lower the car?

According to Stillen's website it is the DRS that I will need, front and rear...

STILLEN : H&R TRAK+ Wheel Spacers

Yes, sorry for the confusion...I get the letters mixed up all the time...they are the ones with the longer studs. My original post is edited with the right series.

And the control arms front and rear?

Well, I lowered mine by 3/4" front and 1/2" rear. With my spacers (15mm front, 20 mm rear), my camber was -1.6 and -1.0 front (yeah, different on either side) and -3.0 rear. With the stock rear camber adjustment bolt, they could bring the rears back to -2.4, no further. And like I said, for the front...no adjustments possible. So I suppose it depends on how much "off spec" you want to tolerate. Some people don't bother with aftermarket camber arms. I wanted complete control of the adjustments and I was in it so far anyways so paying a little more for front and rear kits was fine for the ability to fine tune at any time. In fact have a more aggressive street/track set up right now.

@djpathfinder - I have the SPC kit for my 2006 350Z and it works great. I got the first one they ever made for production! Anyway, I hear some knocks from time to time and it's a little annoying. I put H&R springs on that car which, like the 370Z, lowered it 1.3" front and 1.0" rear.

On my new 370Z I want to make it perfect and I would rather NOT wear out my tires prematurely, however, I do want to put Michelin PS2's on it....anyway I digress....I think I will probably get the SPC upper control arms again and the Eibach rear arms, H&R springs and wheel spacers.

I don't know if I need the Eibach Camber Bolt Kit, still trying to get confirmation on that. If you have a look at the creator of this thread you can see some negative camber on the front of the car. The SPC upper control arms will get rid of this for sure and the tires will last longer as a result.

Any replacement tire is going to cost about $300 so it's certainly worth doing....

The SPC front upper control arm adjusts for both camber and caster up front. If you buy the SPC rear camber and toe kit, it comes with a camber arm and toe arm with a set of bolts for each, so you don't have to buy separate bolts. It is preferable to have the camber arm over just the bolts...again, allows for greater control and adjustability. SPL is another company that makes a high quality camber kit as well.

Regarding negative front camber...I have that too...on purpose, to improve turn in response.

That's odd your front left and right camber is so different. I think mine came out to 1.7 and 1.9. I'm assuming when they adjusted toe it brought the camber lower and closer to matching.

It was weird...I was surprised how out of whack it was too...this was before they adjusted anything. But, it's all good now.

Actually, I got my car corner balanced and aligned at Cantrell Motorsports in Kirkland back in August.

Woah didnt know this thread started up again, but to help with the answer everything mentioned in the original post minus the widening of the toe bolts will put you within spec. Keep in mind when you go to get your 370z aligned bring in a copy of the alignment specs (somewhere on this website, can't remember where, sorry) because since the car is so new they might not have it in there system. Oh and i mentioned in a pm that camber was less than -1 in front, sorry it's more like between -1--1.5 which is still good, it helps with turn in response. So far at about 1400 miles (80 miles was when everything was installed) everything is good as far as tire wear, noises, etc.

Appreciated....

I'll do these things in the next month once my springs come in.

How does the car feel now with the H&R springs? I am trying to figure out which spring I should go for and am having a hard time finding definitive reviews on each.
