To drive a 5th Gen fast you want stability and predictability in your handling. That starts at the foundational level with bushes. We want the arms to articulate freely, but within a tighter operational range. The amount of lateral movement in the 5th Gen lower rear arm with OE bushes and even with Pedders bushes is to great when you are looking for 1/10th or a 100th in a corner. We'll be testing this banded thrust bearing system this weekend. It is going to shift the load and our testing is designed to find out where ans what if anything we break on the Raymond's Performance Camaro and the L/28. Our best guess is that the arm will fatigue and we'll need to replace the lower control arms frequently. If that is all that we find, swapping out lower controls arms will cost less than the fluid changes between events. The track is not forgiving, it will tell us we are brilliant or idiots this weekend.
While we are on the subject of lower control arms, here is a how to on removal of the OEM lower inner control arm bush. The OEM rear trailing arm bush is great for driving in the 8/10ths range. Pushed to 10/10ths or 11/10ths it allows too much movement creating instability. Installing a steel jacketed bush into the knuckle position requires it be removed from the car. Once off the car, the installation is straight forward. The increase in stability is enormous. You can see why in these pictures and the video. Stop by Raymond's Performance to see what Bruce is doing Thursday and Friday with both OPTIMA Challenge Camaro's. |

It looks like I will mess all the fun.
We will end up getting to Indy some time Thursday and setting up the dyno and then have to leave early Sunday. |

I have a need for an hour of dyno time 4 or 4:30 on Friday. Do you think you can make that work? I would say more, but have been sworn to secrecy |

Can you install street 1 at the track, or does it need to be done in your shop?

The oval is out. The West portion of the Road Course is in.
The oval would have been fun, but I have no doubt that more than one C5 member would have kissed a wall. No matter how I ran possible course layouts the oval walls were too close for comfort. We are going to have a FANTASTIC Autocross. Especially if you Pedderise at Raymond's Performance |
