I had some lowering springs installed a couple weeks back. Gave it time and drove it around a few days, and the height doesn't seem right.
I am planning to preload the suspension. Question is, is it necessary to remove the wheels?

 

yea, if I recalled you have to jack it from the rotors while tighting the upper bolts Its been awhile since I've done anything with my sepensions

 

Yes, you need to take off the wheels to access all the bolts.

And DO NOT jack from the rotors.

 

Yes you need to remove the wheels. Reference this thread for loading procedure.

Yeah, I saw that thread, but couldn't see the pcitures anymore. Thanks.

 

I've done 4 or 5 coilover installs now. If you have any questions feel free to pm me.

 

I never had to remove the wheels to get to the 2 17mm bolts. The shock travel is long so theres a big gap when u jack the car up. Loosen them and lower it down and then tighten them, sometimes it takes a month for them to settle. But theres different ways to do this.

 

First of all you are not preloading the springs. You will be preloading the suspension bushings.
