So i had the car aligned today and everything is good except the front camber. I understand there is no factory adjustment for that. The guy said it might cause the car to pull a little. So the car does pull to the right but not badly. What do i do?

The problem is the front caster split from right to left...But you already know that. Follow the TIS directions to correct. The negative rear camber should help reduce the tire contact patch and reduce traction on the drag strip. Good luck. |

Drag setup with camber ? lol positive camber maybe so when the car "squats" wheels whould be perfectly straight.
How much you're lowered ? I guess too much |

I then provided more detail about what is wrong with your alignment, which you also felt that “no way did you contribute to the question”. I had no way of knowing your experience level or understanding of the alignment readings….you were asking for input. I also understand that you might not realize that I brought my experience to your problem with the desire to assist. So let me qualify my answers. I taught Automotive Technology classes from 1973 to 2015 at the college (part-time) and high school levels (full-time). I have taught students how to use the alignment equipment that is in current use during that time (and the old methods from the 70’s). As an instructor I have attended hundreds of automotive update courses provided by many vehicle manufacturers including BMW NA. I was a multiple ASE Master Certified Technician and have my name on record in the Automotive Hall of Fame for that status. I have not continued my ASE certifications in retirement….my wife doesn’t require it. I began drag racing in 1968 and have hundreds of runs mostly at OCIR (Orange County International Raceway, which is gone). I had the opportunity in the early 70’s to campaign a SS/DA 1970 Hemi Challenger in division 7 which for a time held the NHRA National Record for ET and Speed. I was off to student teaching and teaching 3 classes as a grad student at CSU Long Beach requiring that I leave the driver’s seat to get my career started. I also had a street 1968 Dart GTS 340 that ran 13.13 at 110 mph (in the late 60’s). I have had over 6000 students that been enrolled in the Automotive classes and many have raised their hands with a question or two. I have always enjoyed helping students and forum members with their questions and didn’t give up when they were struggling to understand. So here I am again trying to help you. Unfortunately the alignment technician did not help your front right pull or make a rear traction improvement. 1. There is a camber change possibility for you cross camber problem, but requires additional parts and labor. Your car is near the 0.5 degree max for cross camber (left to right side difference). The front Left side could be corrected closer to right readings which should solve the pull. Remember there are other problems that can cause the vehicle to pull, from simple tire pressure to dragging brakes on one side and even suspension damage. You alignment printout does not show readings (SAI) that would be helpful for diagnosing damaged suspension components. Because this is not a brand new vehicle there is the possibility that damage could be the cause or even miss assembly of parts after the changing the springs. You can see another forum member post for a complete printout example here: http://f30.bimmerpost.com/forums/sho....php?t=1340242 From the manual “Camber correction swivel bearing are used to correct the camber values by ±30 minutes. To be used only if the camber tolerance values are exceeded and undershot” There are three different swivel bearings available. You can locate the needed correct part number after identifying the number on your current bearing. Then using RealOEM.com you can look up your specific vehicle based on VIN and locate the part in front suspension section. There are other methods also. Example Camber Plates. 2. Your rear traction would be improved on the drag strip by setting the rear camber to zero degrees which will allow more tire contact patch. Without drag specific tires you will unlikely have much rear squat that would change the camber much from the zero setting. You could get someone to video the tire to rear wheel arch at launch to analyze the height change. Then back on the alignment machine you can load the rear suspension to the launch height and check the rear camber. You can use tie-downs to load the chassis on the rack to verify where the camber goes under a load. You might even need a static positive rear camber to achieve zero camber at launch. |
