So, to be very specific, I will need FRONT control arms, REAR control arms and a eccentric elimination kit. I'll be able to adjust my camber to whichever I want in a limited range, the more negative I go, the more cornering grip it will have with the expense of tire wear. Why would SPL recommend the toe bolt to me twice instead of the eccentric elimination kit they have on their site? I spoke with SPL and Z1 again to get the concept of it and I get it on why I need those parts for cornering grip or stability, tire wear etc.

This is interesting, as the Z has rear negative camber in stock form, around -1.5, which will increase if you lower the car, but this isn't the full story, when you lower the rears, the toe will be more inward.

More negative camber isn't that bad, but excess toe in is bad, this will make the rear more tail happy, and it increases unusual tire wear.

I am 100% sure SPL AND z1 are not the causing the confusion. You're missing what they (and we) are telling you. You also aren't reading the product descriptions right on SPL's website

Stock 370z has eccentric toe bolts to adjust camber and toe in the rear. There is Zero front adjustment. The flaw with these bolt should is that they slip over time.

SPL sells these SPC (note difference) to toe bolts which REPLACE the stock toe bolts and offer slightly more adjustment. They have the same flaw as stock bolts but they are a cheap option for non high performance use

The SPL ECCENTRIC LOCKOUT kit replaces the rear camber and toe eccentric bolts and ELIMINATES ALL ADJUSTMENT from them. They become "locked" in place, hence the name lockout kit

As stated in their description, this kit is for folks who have their rear adjustable arms, because THATS where the adjustability lies. The arms are more stable and offer more precise alignment capability, far superior to the oem eccentric bolts. So you get rid of the failure point of the eccentric bolts and gain the greater adjustment of the arms ....but you have to get the arms

If SPL suggest the replacement bolts, I'm sure it was because you were squeamish on the phone about suspensions mods and they figured you were being a baby again about suspension modifications in your sports car

You seem bothered. Why even read the post if all you have are insults? It doesn't seem too well for your blood pressure. Maybe you should just ignore the thread? That seem easier and less waste of your time.

Maybe you should read what i wrote and say thank you?

Funny you wanna talk about doing things easier and not wasting time when this whole thread has been folks using THEIR time to help YOU, and all you got is excuses and whining about your feelings

Seriously, don't worry about me.

You came to this forum for help and multiple people have been generous enough to provide info, including me. Show a little goddamn apprecation

If all you wanted was affirmation about you already knew and wanted to do, go find a mirror and lick it.

I think, ultimately, SPDKING just needs to educates himself on camber, toe, and caster. Since his car is not a daily, and he seems to be a novice in terms of tackling corners, he has time to sharpen his skills and discover things for himself.

If he’s only keeping this car for a short time, all these talks may just be a moot point.

However, he should follow suggestions here if all of following applies:

-he’s serious about throwing the car around corners
-he’ll keep the car for a few years
-he has the financial means to do everything up front (which can save mucho $ in the long run)

As I said, handling upgrades are something I've never done before passed tires on my 350Z and my M3 and I've recently showed interest after hanging around 911 guys on Canyon runs and watching them lose to highly suspension tuned 370Z's and Genesis coupes on the track in corners with barely any power mods. I can tell you about my Greddy Twin Turbo I had on my Z33 or ecu tuning I got done on my M3 but I've literally never done anything in the handling department ever because I've never been around anyone that talked about that stuff and I'm no longer interested in that anymore. I looked at how fast my car can go in a straight line or how high I can get my top speed over stock. And I plan on keeping this car for the next 30 years or if it gets wrecked in an accident, whichever comes first.

I've boiled it down to me needing everything in this Z1 kit but buy the parts from SPL because I don't know if Z1's quality is all there because I see they are using a SPC rear tow bolts which people said aren't any good and skip the lockout bolts because I can't adjust the camber passed -.5 degrees. https://www.z1motorsports.com/z1-pro...e-p-12183.html

Dont get the z1 ****

Search for prior threads on this. Folks have had provlems with them


Get the spl stuff that we’ve been telling you about from the start

You making this harder than it needs to be
