Those of you who track your V1s, what alignment specs are you running?

Do you leave your track settings for street?

This is where i'm at currently:
LF CAMBER. -2.0
RF CAMBER. -1.8
TOE -0.14 DEG. (not sure what this is in inches)

LR CAMBER. -2.7
RR CAMBER. -2.9
TOE -0.03
Stock 18X8.5 wheels, no spacers
245/40R18 NT-01s or RS-3s

Wears the inside rears as you would imagine. Seems too much rear camber even for the track.. what you guys think

Don't know much about this myself. But cadillac faq has some info under "wheels and tires".

This was about the max I could get. My car is a bit lowered. Your probably at the max.

Front camber was adjusted to -1.8 Left Front and -1.9 Right Front (with me in the car) -1/32 toe each

Rear camber was adjusted to -2.3 Left Rear and -2.5 Right Rear (with me in the car) +1/16 toe each

I did the "Aggressive Street."

Here's what the rest of the FAQ says:

Here are the most up to date values from the service manual... FG2's don't make a difference on the alignment settings... (June 10, 2006)

old settings

FRONT

Camber: Range: -1.0 to 0.0 / Optimal: -0.5
Caster: Range: 4.6 to 5.6 / Optimal: 5.1
Cross Camber: Range: -0.5 to 0.5 / Optimal: 0.0
Cross Caster: Range: -0.5 to 0.5 / Optimal: 0.0
Sum Toe: Range: 0.0 to 0.4 / Optimal: 0.2
Toe: Range: 0.0 to 0.2 / Optimal: 0.1
REAR

Camber FE1: Range: -0.6 to -1.4 / Optimal: -1.0
Camber FE3: Range: -1.0 to -1.8 / Optimal: -1.4
Cross Camber: Range: -0.75 to 0.75 / Optimal: 0.0
Sum Toe: Range: 0.0 to 0.40 / Optimal: 0.2
Toe FE1: Range: -0.05 to 0.24 / Optimal: 0.12
Toe FE3: Range: 0.0 to 0.24 / Optimal: 0.12
Trust Angle: Range: -0.15 to 0.15 / Optimal: 0.0 Note no FE4 entries... but they shouldn't be *too* far from the above. Based on the above ranges, what works well on my Z06, and looking up what M5 guys are running, i cobbled together some recommendations (haven't tried these... just MHO):

Track Front:

-2.2 degrees negative Camber (if you can get that much)
As much Positive caster as you can get without sacrificing camber.
Neutral (0) Toe to 1/16" Toe OUT Each, 1/8" Total Max. [1/16" Toe out = -0.06 deg]
Track Rear:

-2.2 degrees Negative Camber (if you can get that much)
1/8" Toe IN Each, 1/4" Total Toe IN [1/8" Toe in = +0.12 deg]
Rear Toe should never be Toe out (negative)

Aggressive Street Front:

-1.0 degrees negative Camber
As much Positive caster as you can get without sacrificing camber.
Neutral (0) Toe to 1/32" Toe IN Each, 1/16" Total Max. [1/32" Toe in = +0.03 deg]

Aggressive Street Rear:

-1.5 degrees Negative Camber
1/8" Toe IN Each, 1/4" Total Toe IN [1/8" Toe in = +0.12 deg]
Rear Toe should never be Toe out (negative)

What is the Max front Caster then?

Factory says 5.10* +/- 0.60*. How much can you dial in while maintaining that camber?

How is your tire wear with these settings? You change for street?

I am about to get my alignment done. I will be using the car for majority street driving with weekend canyon/trackday/cruises. Will aggressive street chew through my tires? I just bought brand new pilot super sports so I want to get the alignment right. I have H&R springs and rear camber adjustment arms.

I'll see if I can find one of my alignment print outs when I get home this evening. I run a bit over -2 camber front and rear. As I recall, one of the alignment techs told me going any more than about -2.1 or so up front meant you had to start losing caster, so he didn't dial in any more negative camber.

My biggest question is the toe settings. Again, I'll have to look at the alignment print out when I get home, but I've always been confused about the inches vs. degrees conversion. All the alignment racks I've ever been on use degrees. I can't get the conversions provided in the FAQ (1/8" = 0.12deg) to work out mathematically - I don't understand how they arrived at that.

Based on my experience, I definitely concur with toe IN for the rear (so a + number). Toe OUT in the rear makes the car quite twitchy. YMMV, of course.

I've just left the track alignment on the car and haven't had any tire wear issues as of yet.

No.

What are those?

The adjustable suspension piece that allows you to adjust your camber in the rear. Sorry for the wrong description.

Unfortunately, your description isn't helping, as I'm not aware of anything that will allow you to adjust camber in the rear (well, other than the factory adjustment). Can you post a link? I'm curious what you've got.

They are these: http://www.bmrsuspension.com/?page=p...d=68&catid=201

I was talking with Sean from Trinity Tek when I got my wheels and told him I wanted to be able to adjust the camber in the back and he sold me those. This was before I got up under the car and saw how much the stock camber can be adjusted without these. I don't know if these will even offer more adjustment than the stock stuff. I just wanted to make sure I could align the car correctly since it is lowered.

Will I be able to get the "Aggressive street" alignment with the stock suspension pieces lowered on H&R's? Is it even necessary to install these to get the camber right in the rear?

AAIIIC

Those are called toe rods because they adjust toe. They won't do dick for camber. Sean from Trinity Tek didn't do you any favors.

I believe so, but getting rear camber where it needs to be may be tough because of how much the H&Rs lower the car.

No, because they don't adjust camber.

If you don't want them, I'd probably buy them off you

I understand that, I even asked him when he was selling them to me, I said "even though these are toe rods, they adjust the camber right?" he assured me that on the ctsv they do. I personally had not been under the car yet at the time and don't know enough about the suspension so I took his word for it. Did he really just lie to me to get a sale? I was skeptical when I saw the piece, and saw the description that said "toe rods", so I asked him to confirm these will adjust my camber and he assured me they do. I am kind of irritated right now.
