The giant sticky up top has all the numbers you need from hotchkis, pedders, or pfadt. Print one and take it to the alignment shop as they say exactly what caster, camber and toe to do which you're off on all of them. Also take it to a place that will take the time to make it even left and right more so than a range.
Cradle and differential bushings would probably help too. |

less rear camber will help as the camber increases negative value as the suspension drops during load.
dont try for zero rear toe, it is too risky if you get off a little and have toe out at all. with any rear toe out it will be very twitchy. i go between 1/4 and 1/8 inch total toe in, 1/4 for raceday, 1/8 for drag and street. I did the math backwards and you are less than 1/32" total now. So i recommend more toe IN the front alignment will only help for cornering, I thought stock caster was 7 degrees? am i wrong there? more caster will help once you get sideways, it will pull the steering wheel to hold the car from spinning out. I always have as much negative camber as possible(isnt much) and a slight toe out(1/8" total toe) I am still interested in the effects of the suspension drop during launch, if you have it up on the alignment rack, you should throw some weight in the trunk to see. you still might have the entire rear subframe moving. the stock mounts allow almost an inch of movement!!! the best is to get the pfadt subframe mounts, but around $650 and a bitch to install I was going to recommend the hotchkis chassis brace, but it looks like you already have it. the hotchkis brace holds really well for straight line accel, but i am so abusive to my car, i need more lateral support, so i made my own, works really well at the track, totally feel the difference you should stick a gopro down there to see if anything is moving

1. What are the rear ride heights measured Pedders style in mm? [IMG][/IMG] 2. You are on OEM coils and struts? 3. The sub-frame bushes are still OEM? 4. What is your tire and wheel package? |

Bush Timing Step 1. Lift the car on a two post lift and raise it. Step 2. Loosen the following bolts/nuts: Front: ---Inner Control Arm Bushing ---Inner Radius Rod Rear: ---Trailing Arm Bushings (both ends) ---Toe Rod Bushings (both ends) ---Lower Control Arm Bushings (Inner) ---Upper Control Arm Bushings (Rearward) ---Lower Strut Bushings Step 3. Lower the car and drive it around the parking lot SLOWLY and on to the alignment lift. Step 4. With the weight of the car on the wheels tighten all of the nuts/bolts to spec. Step 5. Align the car at the new ride height. |

There isn't much left to look at.
The guys with the corner weights are on to something and it ties into ride height. The lowest rear ride height wheel will have the least amount of weight. The The tallest, longest will carry more weight. Using corner weighting scales you will be able to get and even load across the two rear wheels which will help keep them straight. I know you are on coils and not coilovers, but you can shim the upper strut mount plate Getting a good accurate rear ride height measurement is a good place to start. The root cause of your IRS instability will eventually be traced back to the OEM sub-frame bushes. Brace or no brace they are still moving. Switch them out to Pedders EP1201HDs and bolt your brace back in place. Run a few tests. If they are not better I will refund your purchase price and you can keep the bushes. I am able to make an offer like this for two reasons. First, I have a vague idea that it will work and two, most of the people here on C5 are true enthusiasts and I can depend on their integrity. Even with the EP1201HDs installed, we still want to corner weight and adjust the alignment after to squeeze out every 10th and there might be one or two more tricks we can apply to your car. |

You could go all in and bolt on 2/10th in the 60'... http://www.detroitnews.com/article/2...ros-multi-task Lingenfelter carries out testing of its 5th Gen Camaro Drag Race Suspension Kit, which is designed not only for the drag strip, but also for autocrossing and daily street driving. (Lingenfelter Performance Engineering) Get 500 people and their late-model Chevrolet Camaros together, and it can be an eye-opening experience, even for someone well-versed in such things. It was about a year ago that Mike Copeland, operations manager for Lingenfelter Performance Engineering, attended an event in Arizona hosted by Camaro5.com, a website focused on the rebirth of Chevrolet's modern muscle car. "It was amazing to me to look at the demographics," Copeland said. "There were people there from 22 years of age through 60 years of age and of their 500 Camaros, there couldn't have been more than two that were still stock. Everybody was modifying them." That is good news for companies such as Lingenfelter. The company has been producing high-performance parts for Camaros, Corvettes and other vehicles for going on 35 years. Based in Decatur, Ind., Lingenfelter Performance Engineering was founded by the late drag racer John Lingenfelter and is now run by his cousin Ken, a Detroit-area businessman and car collector. "They sell 100,000 Camaros a year," Copeland said. "There's a large number of those people who are willing to modify their cars." But, he added, where in decades past someone might modify his or her Camaro specifically for autocrossing or drag racing, now those car owners want to be able to do both exercises — and still use their car for daily driving. To help make that possible, Lingenfelter has launched its 5th Gen Camaro Drag Race Suspension Kit, which is available in two versions. The kit is designed for 2010 or newer Camaros, cars, Copeland said, that their owners aren't ready to or cannot afford to turn into all-out racers. One version of the suspension kit retails for $4,495 and includes Lingenfelter by Pedders double adjustable drag racing shocks and custom Lingenfelter by Pedders coil springs for front and rear wheels. The complete package, priced at $6,750, adds several special rear suspension parts: adjustable trailing arms, adjustable forward tie rods, adjustable stabilizer bar end links, a 1-inch tubular adjustable anti-sway bar, differential bushings, aluminum rear cradle bushings, and an underbody chassis brace. "Typically, when you design a drag race suspension, it's only good for drag racing," said Copeland. "But these are double adjustable so you can still have a good handling street-driving car and go to the autocross one weekend and to the drag strip the next weekend. "If you were going to do a full-out road-racing car, these are not the shocks for you. But if you want to road race one week and drag race the next week, these are for you." Yes, he said, engineering such a setup was a lot more work to extend shock travel and fine-tune shock valving. The hardware is designed for standard-weight cars (not for specially lightened, racing-only modified vehicles). It also enables ride height changes without affecting spring preload or overall shock travel. Copeland said Lingenfelter equipped its 2010 Camaro "shop car" with all the competitive aftermarket suspension kits. "We were able to make the car two-tenths of a second faster just by changing to our shocks and struts," he said. "Typically, people with new Camaros focus on one of two things — performance or aesthetics. People who want the look will do a body kit and wheels and tires, and then suspension. People who focus on performance will do engine upgrades — such as superchargers — and then they'll typically go the suspension next." Either way, he said, Lingenfelter's suspension setup can be part of the package. See www.lingenfelter.com for details. Larry Edsall is a Phoenix-based freelance writer.
