how to set the correct angle on front control arms.

[93efini]

I have a 2007 a4 avant which is lowered on st coilovers at the highest setting. My commute to work includes going over a minimum of 10 speedbumps in a parking garage everyday and I'm constantly hitting the bottom of my car on these stupid things regardless of how slow I go (the speedbumps are rubber so I'm not doing to much damage). Needless to say I'm over the speedbumps so I have decided to raise my car back up to stock height. I purchased new shocks and I still have the stock springs and I plan on getting the full upper control arm kit from meyle https://www.ecstuning.com/b-meyle-hd-parts/complete-heavy-duty-front-control-arm-kit/1160500085hd~mhd/. The question I'm still struggling to answer is how can I get the correct ride height my car will be at so that when I torque the various control arms down they will be correct and not stress out the bushings. I know I can put in the struts in and put the car on the ground and then measure and take it all back apart but I would rather just do it all at once if possible. Any suggestions would be greatly appreciated thank you.

Measure from the center of your axel to the fender when the car is on the ground with the wheel on. Resting position.

Jack your car up on a jack stands and put your jack on the upright (protected) and jack up the upright until your measurement is the same. Torque down your control arms.

The absolute best way to torque down control arms is to do it on an alignment rack. Short of doing that, the method I described works better than just winging it.

You have three options:

1 You can purchase a service manual like the phuk'n rest of us![:D]

2 With the strut assembly out and reassembled, place a straight edge on top of the top hat protruding out past the end of the control arm. Measure down to the top center of the ball joint. For the upper front control arm, the measurement is 81mm. For the upper rear control arm, the measurement is 70mm. The upper rear arm has a nub on top. Do not measure to the top of the nub but to the bottom where it meets the control arm. Torque to 50nm + 90 degree.

3 With everything reassembled on the car, use a steel tire hanger or a large enough bolt for a lug and lower the car onto an elevated jack stand. This should give you your ride height. Measure from the center of hub to fender. Non sport should be around 15" sport around 14" It can very from side to side by .25" to .5" so don't sweat it. If it's more than .75" be sure to adjust it.

Seeing as how you are replacing the front control arms, at the very least, I recommend replacing the rear upper control arm bushings. Have them pressed in it's cheaper than replacing the whole arm.

It's been almost a year since I replaced the rear suspension. It wasn't until just recently that I saw the off brands started selling the rear upper control arms. I also have my own press.
