SPL adjustable FRONT camber arms FYI
 

I just got another e-mail back from SPL and they said that the 370z front control arms are still in development, but are scheduled to be released in the next six months. I think the SPL stuff is excellent and definitely better than the current SPC offerings. I just hope I can wait that long. The outer edge of my front tires is taking a beating and I need to get some more camber in there. Maybe AM Performance will get something out there first.

Very interested in that as well!!! As long As these products are out before next season it will be good!

They've been "in development" for a LONG time now no?

Yeah, but this is the first time they gave me a delivery date.

I've heard that story before

:iagree:this song has been sung for along time.:bowrofl:

I emailed them about a week or two ago and they told me there was no date and that the economy has been especially hard on them. I'm going to buy some arms shortly and I won't be waiting for these. Doubt it'll be 6 months.

I did SPC all the way around. Zero issues. I am lowered on Swift springs

SPC is a great kit but when pushed hard like at the track it can slip a little due to it's design. The SPL setup is defiantly better in design. On the SPC you might just have to tighten down the top nut tighter than what it's called for.

Mike uses the SPC front arms and said he's had zero issues. He uses the car solely on the track. I'm favoring the SPC kit now and then using some blue locktite on the bolts.

Don't get me wrong I love the SPC kit also. Even had one on my 350 also. I've never had an issue before either. But if both kits were out I'd probably choose the SPL front arms over the SPC. The SPL is a little easier to adjust and hold your settings while during an actual alignment. You just have to tighten the top nut more and I assume the locktite will help. But even then it CAN slip due to its design. Probably more so if you hit a bad pot hole. But even then that could threw any kit out of alignment.

Mine never slipped and you know we drive our cars alittle hard than going to church on Sunday.:eekdance:

Another thing about the SPC kit is that mine seems to smash into my fenders when I hit a bad bump on the freeway or any sort of high speed traveling. I'm not the only one who has experienced this either.

^ I get that from time to time also. Only a handful of times. More so when I was lower than I am now.That's one reason why raised it up a 1/4'' and soften the dampner a little. I was also scraping the inner liner.

the spc slips pretty easily if you drive hard with grippy tires

I have about 1000 miles on them(with grippy tires) and drive my car like I stole it,plus I did my own alignment so tightening the upper ball joint correctly was not an issue I'm not doubting that some people have had a problem but maybe the person tightening the nut may want to think outside the box to achieve what needs to be done.

I'm just saying.:hello:

I thought you had v12s???

Yes I'm do and they may not fall into your category of sticky,but being a 30 series in the front and 25 in the back it is to short for side wall flex and these tires are alot better than people on this forum give them credit for.

yeah, but not even close to the realm of what I'm talking about. Of course you won't be slipping the adjustment running 20" v12s...

These tires are rated 8.7 dry traction,I forgot that all you guys think that the most expensive tire is the most sticky and you being 21 have drove on every set of tire to confirm that the Hankook V12's aren't as sticky as "more expensive tires.

the reason the upper ball joint slips under pressure is a design flaw and I knew about this when I did my alignment ,so I was able to fix SPC flaw that's why is doesn't slip,and it can't move or slip regardless of what wheels or tires are on my car whether it be my track 18in or my show 20in. :tiphat:

got pics of your fix to contribute to the rest of the forum? I know there are a lot of people that would love to follow suit.

No need to get all defensive and get your panties in a bunch over the fact that the v12 isn't a competition tire (which is what most people that need a front camber kit will run)...it's not even in the realm of re11's or azeni's...or whatever other aggressive street tires we run.

Not sure what me being young has to do with it...but yes, I've probably got more experience with different tires than you do.

Pilot Super Sports :stirthepot:

or star specs...or even the stock advans or re050as...

The flaw I fixed is a adjustable shim that fits in the space where the ball joint resides and when adjusted to your liking tighten the nut to spec and leave it be.

Most people including you,me and probably 80% of this forum if given a car completely set up properly could not use it to it's full potential,hence searching for the stickiest tires are irrelevant.

full potential? no, but I do compete at a level where running a sticky tire is important and beneficial.

I have the SPC and they do slip sometimes, mostly on tracks with nasty transitions such as SP Shenandoah, NHMS and probably any other oval track with a road coarse. I think on smooth tracks it holds okay.

I use 100TW or 30TW tires.

Is there enough room in the grooves of the SPC adjustment to put two more bolts in there to hold your setting? (think...sandwiching the main bolt with one more smaller one on each side for support)

I saw slip on the SPLs just autocrossing on v710s...

Interesting concept, it will be something I have to look into. I would just tack weld it to the desired setting but the metals are dissimilar. Note that the lock bolt never loosens up, it just slips in the grove.

you can now remove me from the 'zero issues' column.

What happened?

one slipped out of adjustment. went from 3.5 degrees negative to some amount of positive camber.

Ichiba and Kinetix both look like they have the same design as spc.

AM Performance
 

I have an e-mail into AM Performance to see when they might have their front arms available. I was told so far that they just finished the race season but weren't focused on customer parts yet. Maybe if some other interested parties contacted them too they might hurry that up. Right now the other available arms kind of suck. I'm sure anything from AM Performance will be "race proven".

Did you mean to say SPC or did you have SPL's?
