To move the camber significantly, you would have to move the outer rear a very serious amount outward; Way more than what I think you indicated. It is interesting that this exchange you and I are having, is the only time I think this has ever been discussed. I would imagine no one even knows about. I have measured front and rear bump steer after following a TrackII install, and the guidelines in the PDF below and they were nearly nothing. I have not checked it bump steer when adjusted in the opposite direction. Now Holden does recommend to pull the rear bushing assembly outward to reduce rear bump steer to the max. Here is an internal info letter that describes the bump steer issue for the rear: Mike dms |

That's what I was told too...
Got back today from my good friend's garage. John's been doing alignment for 20+ years and his shop has a sophisticated, laser guided alignment machine.
The first thing John says after getting the Camaro up in the air is: "no front camber adjustment". He points out the top and bottom stock strut bolts and says they are not meant to be loosened and played with to adjust for camber. My old Gen3 had regular bottom strut bolts, but the Gen5 has these serrated, lock nuts that Johnny says will cause the front suspension to come out of alignment(?). After a bit of looking around, John pointed out the camber bolt holes and says I need adjustment bolts. But he also says it can be done with adjustable lower control arms too? I trust John and we left the front camber at stock. But all over the Camaro5 website, everyone says front camber is doable without special parts. So what gives you guys? How is front camber adjustment achieved? I'm seriously thinking about the Pedders alignment bolt kit now. But can you Pedder guys tell me if they come with comprehensive instructions? Especially about elongating the castor adjustment hole? Anyone make adjustable lower control arms? John observed that the Camaro's front suspension is "European like" with double ball jointed knuckles and the adjustment holes. After I told him the lineage of the Zeta platform Camaro, he's more convinced that it's not a "typical" pony car setup. John works mostly on BMWs, MBs and exotics. He was doing a recently lowered 2007 Aston Martin DB9 before my car went up. To him, "it's all the same". The front camber at stock measured out at -1.1 left and -1.0 right. We set the front toe to zero (factory was -0.15 left and 0.35 right!). Rears have camber and toe adjustments, so we ended up with -1.1 camber (max'd out) and total +0.2 toe in. I can feel the rear being more planted, but it can definitly do with way more negative camber. The steering response is also improved with the zero front toe.

The front end camber is adjustable. The issue is there is not adjusting screw for it to make it simple.
Having the rear cambers at the -1.1 degrees is great on keeping the back end "planted" as you said. But it does increase understeer, which is dominate in the Camaro. Your overall handling will be improved if you can adjust your rear cambers to equal approx 50% of the your front cambers mike dms |

I'm aware of the understeer issue, but for slaloming, understeer is preferrable to oversteer. So, can you explain to me what needs to be loosened for the front camber adjustment. My friend says you can't undo the top strut tower bolt or the bottom two strut bolts. I now understand the use of the adjusting bolts, but where are the front camber adjustment points so I can enlighten my friend?

Take a close look at this picture. You will ssee the camber screw installed in the knuckle above the brake rotor.
you can order the Camaro alignment bolt kit from Pedders or just use a bolt as a temporary adjustment tool in the shop. Loosen the clevis bolts and turn the screw in to reduce camber and out to increase camber. |

Tom,
You are welcome. The camber screw specs are M10-1.5 X 40mm and any bolt will do on the alignment rack. Once the camber has been set the bolt can be removed. If the camber screws from the G8 were readily available you could use those too. If you use a Pedders camber screw or any screw other than the OEM screw it is important that you load it up with blue LocTite so it doesn't come loose while driving. As it has no real load on it there is little to keep it tight. Our technical term is goobber it up with the blue stuff Pedders didn't invent the 5th Gen Camaro screw, we just tell people how to use it |

I bought the front camber bolts, Now what I need is a sheet to have the car aligned to. I don't understand the -1.1 and stuff. I'm going to take it to a shop, but I need what the guy at the shop said is a sheet full of alignment specs.
Thanks for any help. |
