A tech who did my alignment yesterday couldn't get as much alignment on my C6 as I had hoped. He works on Ferrari Challenge cars and has the top-end Hunter alignment machine. I even had him take the washer out behind the A-arm based on a trick I read on the forum. I also had a Pfadt camber kit installed.

So, the most he could get was -2.1 front and -1.7 rear. He said he could get a bit more in the back, but he didn't see how to get more in the front. Do you guys have any tricks I could share with him? I was hoping for closer to -3.0 in the front as I'm running Michelin racing slicks.

Any help would be greatly appreciated.

Did you flip the upper dog bones in front to get more camber?
In the rear, that is about all you can get without taking drastic measures. Be happy if it is relatively equal on the left and right.
You may only be able to get 2.5 or so in the front.

Did he max out the concentrics AND remove ALL of the washers? I was able to get -3.0 personally.

By removing the washers on front upper mounts and maxing the concentrics I got -3.0 also.

This worries me, as I'm having a shop install the Pfadt camber kit on my ZR1 tomorrow morning. Did you install the lower front camber plate with the 'Z' facing you, or away from you?

Also, did you call Pfadt up and talk to Blair their alignment guy? Something just sounds... off... here.

No concentrics with the pfadt kit. Jas, I will call Pfadt up and talk to them. Maybe, the shop that installed the kit didn't put the 'Z' on the right side. There should be more there than -2.1 for sure, I would think.

You should be kissing close to 3* with that setup and no camber shims installed on the UCA.

^This.

I'm running that pfadt camber kit on my Carbon Ed, so basically a ZR1 with a 427 and I'm currently at -2.9 on the front and -1.9 on the rear. I believe I'm just about maxed out on the front right now.

jvp

Do you undo that when you hit the streets? Or just keep the massive negative camber? When I talked to Pfadt yesterday, they didn't think a huge swing would be possible with just the camber shims. Possibly upwards of 2* at most.

I'd be happy with -2.9 and -1.9. -2.1 isn't going to cut it. I'm going to check here in the next day or two and see if I need to swap sides on the plates.

I've said this many times before on this forum, the plates don't give you more camber and the differences that people get is due to differing ride heights. I use the #6 camber plates and get 4.7 degrees of negative camber front and 3.6 rear. I'm running the #1 and #2 plates with about 2.4 degrees in front and rear.
Bottom line ride height will determine the max camber you can get in the end.

Yes I run on the street with the same settings. I'm guessing that my car is like yours, not a daily driver but mostly a track car with occasional use on the weekends or I take it out for an occasional road trip. For street use I run the stock 19/20 PS2's and I'm not seeing any crazy wear or anything like that. Wear I personally believe is predominately caused by dragging the tires due to toe. I run 0 deg. toe front and rear which on the track allows the car to transition pretty quickly.

I'm still playing around with different tire types/brands and plan on leaving my alignment settings where they are until I finally settle on a specific tire brand/compound then might add a little front toe out to increase initial turn in. Should also mentioned right now I'm on poly bushings (so still experiencing some bushing deflection) but will be changing over to monoball soon.

On my 06ZO6 I can get -3.5 on the front no problem with the Pfadt. kit

I could get -3 in front of my Z with the cams. When I installed the Pfadt Camber Plates the most I could get was -2.7. At this time I have the alignment set at -2 with the Pfadt Plates set in the max position with the Z to the inboard of the bolt. I have 2 of their 1.9 and 1 of their .9 shims behind each front dog bone and 1 1.9 shim behind each rear dog bone. Left side caster is 7.5 and right side is 6.75.

One thing I notice about the plates is they don't fit tightly in the cam slot. There is close to 1/16 slop.

I flip the plates over when I want a street alignment. The instructions say to have the curved side upwards but they are so far below the top of the cam slot I see no reason to pay attention to that and just loosen the bolt and rotate the plates on the bolt thus moving the Z from the inside to the outside of the bolt.

Actually, I use mine as a daily, grocery getter, errand runner, and track terror.

check this i bet it is it.

BTW how did the car run this last time you were out??

The way to max out the negative camber is the Camber kit like you have, flipping the dog bone (I know the sphericals from Pfadt have a different dog bone, not sure if it's shaved more or not) and drop spindles as they lower the ride height and have some negative camber built in.

jvp

For what it's worth: my shop is having the exact same issue, and they've verified the Zs are facing the proper way.

There shouldn't be a difference between the associated suspension pieces between the Z06 and ZR1, but something is up here...

Stay tuned.
