There is a price difference between these 2 companies, but FITMENT is what concerns me the most. Unless the fitment difference is negligible, i would rather save the cash as im low on cash.

And i believe one is fiberglass and one is poly, if i went over a speedbump a little too fast and scraped the front, would they both crack? In other words, which one has better value if i were to scrape it ONCE. (not like im trying to, but my luck is crap and i KNOW crap like this happens to me.)

Next, i was wondering if i got the Eibach 350z springs, will i need a camber kit? And exactly how much stiffer and lower would the ride be compared to the stock g35 coupe?

 

poly all the way. I dont believe theyll crack at all unless you wreck or something.
you will need a camber kit if your lower anything

 

Strafe carries Arch's parts

get Poly

yes you will need a camber kit

 

^ partially incorrect on both fronts.

Poly is by far superior, you can litteraly bend it backards and it will come back to it original form. Some companies (not arch or strafe to my knowledge) ship their poly bumpers in a 2x2 box folded up, then you need to put them in the sun to let them pop back to shape. But if you hit a big tire on the freeway doing 70, it's going to go through even a poly bumper. Fitment is also usually better with poly as it flexs and doesn't need to be exactly perfect like glass.

Glass is very fragile and if you were to bottom out on a speedbump or parking stump, you will definitely be buying a new bumper.

You don't NEED a camber kit for any drop, but you will camber tires faster the lower you go and the more camber your car has. Are the eibachs the sportline or Pro kit? Either one, it will drop your car .5" more than it does the 350z so take that into consideration when looking at springs.

Rule of thumb is usually anymore than a 1.5" drop, you should get a camber kit.

It won't ride very harsh to the point where you won't like it, but it will definitely be stiffer than OEM. Stick to the big brands (tein, H&R, Eibach etc)

Wes, that was pointing to the guy about you, not your post... but I still disagree a little lol

 

Wait.. so Strafe and Arch carries the same products?

I would probably never hit my rear or my side skirts, so fiberglass would be safe there?
And poly front would probably work best for me.

Anyone here have any inputs on how well strafe's fiberglass body parts fit? Particularly interested in their Impul ss and Chargespeed rear.

 

glass sides are fine since the front takes more abuse

no part no matter what comp you buy from will fit 100% its all in the prep work the body shop does

either way i have not heard anyone complain

 

Did you PM Strafe and Arch about the difference between the fitment, if any, between the parts they carry? I'm sure they will give you their opinion. Any part you pick up will more than likely require some prep.

 

Just did that, and im waiting for a reply now.

I just wanted to get some inputs on which one to get if i was low on money and don't want parts with horrible fitment.

 

STRAFE can hook you up with everything you need, including springs!

IMO
i say poly front and poly sided, some speed bumps can he HUGE and you can often bottom out. I currently have a CS rear in fiberglass from strafe and it fits PERFECT! just need to prep and paint it. I still need to get my front and side that will be polly, i was on fence about strafe or arch.

 

Get poly and yes you will need a camber kit.

 

Both our great companies, but the fact that arch is willing to stand behind their products more and guarantee fitment wins it for me.

 

we carry EVERYTHING arch offers except his kuruma and poly cs rear. we sell the AUTHENTIC kuruma in poly..

 

i hope you know it is impossible to guarantee fitment with an aftermarket part... but if you want to believe that it is fine

 

I totally understand you can't make something ever time that will necessarily be perfect every time. I mean more in the sense of what happens if a part that doesn't fit very well gets to my door.

More of a comparison of these type of statements:

I understand you are protecting yourself but which inspires more confidence in what you are buying? I really don't want to discourage anyone from buying your products in the least, and only responded since you directly quoted me. If you would like me to remove this post feel free to pm me and I don't mind doing so.
