Damn, so I have to remove the wheel to make adjustments then. I'll try it out before swapping the Eibach's from the front to rear and installing the OEM's I have in the front because then I'd need an immediate alignment. I'm probably still going to get one to check that everything is okay, but I'd like to keep it simple if possible.

cody 2006-05-04 11:22 AM

Thanks guys.

Dean 2006-05-04 11:37 AM

Mucking with any of these will likely require an aligmnent. At this point, I think you have the bolts, so just put them in.

Scott and I at least have camber guages you could use to adjust it, but may as well do toe etc. if you are messing around with it, so take the bolts down to a shop and get it done right.

cody 2006-05-04 11:40 AM

Sid said the alignment would most likely be less than $100 if I installed the bolts and up to $300 or more if he installed them. I was like, Okay...I guess I know which I can afford. But now that I live in Stead, I don't want to ruin my new tires driving from my house to his shop on a Monday morning...

cody 2006-05-04 11:45 AM

Also what kinda sucks is that you install the bolts one way to increase camber and another way to decreas it, so if I used the bolts, I'd have to install the rear ones differently. :?:

cody 2006-05-04 11:51 AM

Hey Dean, Do you think the camber gauges you mentioned that you and Scott have would help me get a decent enough home alignment that I could drive 10 miles on the freeway without ruining my RT-615's?

sybir 2006-05-04 11:54 AM

Dude, you're not going to hash a set of tires in 10 miles if you're not running crazy toe or massive visual camber. Just take it easy, and you'll be fine.

Yeah, I put two days of driving at RFR on my eyeball-aligned car and my tires are still worn perfectly evenly. :lol: You'll be okay.

I didn't even eyeball align mine on friday, I just attempted to reset the eccentrics to where they were on the stock springs, thus guaranteeing a less than optimal alignment for the event. :lol: Who knows how good the alignment was in the first place too. But, my tires are still looking good and no alignment settings could have brought down my times enough to catch Chris Vallentino anyway.

Here's how I did my alignment:

"Hrmm... the car is a bit darty, probably too much toe-out, I'll just put a half turn of toe-in at each tie-rod end."

"Okay, that was probably too much toe-in... I'll just add some negative camber because I'm too lazy to do the toe again."

"Let's check tire temps... wow, they're even across the tire, and the handling feels pretty neutral-to-understeer. Alignment's done!"

I GUESS!

It's just a more technical, "PC" term for N**ger Rigging! :lol:

cody 2006-05-04 01:34 PM

Alrighty then, I'll just install the bolts in the rear so they reduce negative camber and install the OEM's in the front so they add neg. camber and drop it off at Sid's Monday morning and keep my fingers crossed I guess.

Please let me know (PM or whatever) if anybody can reccomend anything (like a better/cheaper alignment shop, etc).

I had to use my stock uppipe as a breaker bar but I was successful at removing 99% of the rubbing in the rear (by doing exactly what I proposed in the above post). After I cracker-rigged...I mean DIY'd my alignment, I used a parking lot nearby to "autox" for a while and I did hear the inside of the right tire rubbing a couple times when I would hit a bump on a hard turn. So hopefully my alignment tomorrow will remove 100% of the rubbing. :)

One thing that sucks is that it looks like the stock camber bolts won't net me as much neg. camber as the Eibach's did.

I used a sharpie to mark the front camber:

Someday I'm going to have to upgrade my sway bars...my car has too much body roll.

cody 2006-05-08 09:59 PM

Sid is the man. I'm now running -1.7 all around (I wish I could run less neg. cam. in the rear but I'd have to roll my fenders...), a touch of toe out in the front, and zero toe in the rear. The stock camber bolts wouldn't get me any more than -.5 in the front but luckily Sid had an extra set of cam bolts that fit the lower holes.

khail19 2006-05-09 06:33 AM

Any rubbing still?

cody 2006-05-09 07:01 AM

Nope. :)

sperry 2006-05-09 09:15 AM

You may want to check the rules before switching to a points class. I'm not sure running two sets of camber bolts up front is legal... there are some odd rules with regards to camber modifiers.

cody 2006-05-09 09:16 AM

Thanks for the heads up. That sucks if that is what ends up knocking me out of ESP.

15.8 Suspension (Street Prepared) Pg. 86
Quote:

G. Camber bolts may be installed, providing these parts use the
original, unmodified mounting points. Caster changes resulting
from the use of camber bolts are permitted.
I can't tell with that wording if they're SP legal or not. My guess is they are since people use them in the rear all the time when they drop the ride height.

Anybody know?

Kevin M 2006-05-09 12:00 PM

Looks like you're fine with both sets based on 15.8.G.

cody 2006-05-09 12:03 PM

Alrighty, I guess I'll just show up with some masking tape on Saturday and cross my fingers.

khail19 2006-05-09 12:05 PM

You're still using stock mounting points, so it looks like you're good. It doesn't say anything about having them installed where the factory didn't.

sperry 2006-05-09 12:13 PM

Well, the rule I'm thinking of was regarding using more than one camber adjusting item.

Dean may have to correct me, since I've (intentionally) forgotten the rules except for SM. But there was somthing about you can add camber bolts, or add camber adjustable top mounts, or add adjustable latteral links, but you can only do one. I'm not sure if that applies to adding two sets of camber bolts... but it looks like you're probably okay, since I'm starting to think those rules were only STX rules anyway.

Kevin M 2006-05-09 12:54 PM

I was thinking of that rule too, but it's in ST, and it says you can only choose between camber plates and lateral links on McStrut cars. It doesn't mention camber bolts.

bruspeed 2006-05-09 01:34 PM

In that case, I'm getting 8 of them.

cody 2006-05-09 03:16 PM

Cool, I was already kind of kicking myself for ordering the OEM camber bolts instead of the H&R's (+/- 3 degrees of adjustability). I was really lucky that Sid had an extra set for the bottom. Seems like everything worked out pretty well...I just hope this alignment doesn't eat tires too bad.

Any opinions on the Progress adjustable RSB? I will need to upgrade the mounts since I have a bugeye and the Progress comes with them all for $175. Does Oakos charge for shipping?

What about the front? Will an upgraded FSB and solid endlinks help body roll? Is it a good investment?

Keep in mind when dealing with aftermarket camber bolts that any extra adjustability over the OE bolt is only going to be acheived by making the diameter smaller, so that there is more room for it to move around within the receiver holes in the spindle & strut ears. This might mean they require a lower torque value than OE (which means less bolt preload & clamping force). We tested some H&R camber bolts at MM in order to figure out if we wanted to use them on the Mustangs, but we couldn't torque them up to the OE spec so we passed.

Seems like this would also make it more likely for the bolts to shift between alignments, maybe Cody should mark the position of each bolt so he can tell if it's moved.

Interesting. Just out of curiosity, did they break when you tried to torque them to OE specs or did you just figure they would break/stretch if you did?

Everything I've read says the OE camber bolts on my car should get torqued to 120 while the Eibach (and most other aftermarket camber bolts) shouldn't be torqued to more than 80. I mentioned this to Sid and he agreed. I have read threads on Nasioc where people have had the aftermarket bolts slip but most people attribute this to overtorquing (and subsequent stretching).

Marking the current position is a great idea Khail. I bet I can get under there and mark it without taking off the wheels...I hope.

khail19 2006-05-10 07:10 AM

If you have your RP02s on, that shouldn't be a problem. I think I could change pads without taking off the wheels! :lol: It's nice to be able to see everything easily with these rims.

They didn't "break" like snap in half, they just yielded.

This is what I was talking about; that lower torque value of 80ft*lb carries with it a lower bolt preload, and thus less clamping force on the strut-spindle joint. A ballpark number for that 40ft*lb reduction is about 4000lbs less clamping force. This is why the alignment will slip easier.

Yah, these rims make me want nice brakes. Nothing like showcasing your rusty stock brakes! :lol:

BTW, I can tell by looking at the dust that sticks to the rear tires that about 2 inches on the outside of the contact patch doesn't even contact the road when driving straight now :eek:

sybir 2006-05-10 07:31 AM

Cody, a dialed alignment is important, but if you're having to crank those kind of numbers on your daily driver to keep from rubbing, you'd be much better off rolling the fenders. Running almost 2 degrees of negative camber, with smaller bolts everywhere, doesn't sound like a good combination for a car that not only has to deal with AutoX stresses, but daily driving on buckled roads, etc. My car is pretty low, and my fenders were narrower than a WRX wagon, but I can tuck 070's and other wide 225's way up into the wheelwells if necessary with no rubbing issues after properly clearancing the fenders.

That's just my opinion; I'd much rather get some fender space and run a less aggressive camber setting. I'm also not influenced by the the fact that I own a fender-rolling tool :p

cody 2006-05-10 07:37 AM

Well, I do think that the rear wheels have too much neg. camber, but Sid seems to think this alignment will be ok for daily driving. I'll keep a close eye on my tire wear and go from there I guess. I'm also curious to see how bad my car understeers now.

What Sybir said, rolling the fenders will pay for itself pretty soon if you keep wearing out tires prematurely. Or you just need to stop going straight and turn a lot more often.

sybir 2006-05-10 07:55 AM

Fair enough. I know it's not camber that kills, it's toe combined with camber, so keep an eye on it. I'm sure Sid isn't trying to steer you wrong, but tires cost money and rolling the fenders is cheap and gives you a lot more options.

I can get the tool up to Reno if you need it.

cody 2006-05-10 08:01 AM

Cool, thanks.

I'm also considering the cost of needing to upgrade my rear sway along with the cost of replacing tires if there is excessive wear. if either becomes an issue...I will be reducing the camber down to somthing like -1.5 in the front and -1.1 in the rear which might require fender rolling with these tires.
