Install the springs, after week or so of driving an alignment is REQUIRED.

 

You might want to check the obvious -- did he torque the bolts properly when he put your wheels back on?

 

Yeah step one was to ensure that they put the wheels back on correctly. And there were no vibrations anywhere close to what I have now when running the stock springs so I doubt balancing would make much of a difference. Anyawy, now that I put some 400km on the new springs I guess the thing to do would be to get an alignment, and if I still have the problem I'll go for balancing.

Thanks all for good and fast replies!

 

A coupple of things from previous expereinces with lower/stiffer springs: they should be done in conjunction with shocks as the stock shocks will not be the correct length with Eibachs. If you have not done shocks, be prepared for replacements in the not too distant future... Sachs makes sport shocks that fit lower prings. Bilstein sports are my favorites.

As for the alignemnet, the settings for the original vehicle will no longer be valid. i usually tell the alignemnet specialist to set the machine to a sport suspension setting.. My 04 530 non sport after lowering would be aligned (approximately) to a 530 with sport suspension veen thoug the aftermarket springs are not exactly the same as the factory sport springs... One thing NOT to do is to have the vehicle aligned to the original specs with modified springs...

fatter sway bars should help with flat cornering even more! Good luck.

 

What kind of vibration, are your wheels pulling? do you feel it over imperfections on the road? Isnt in your seat or is it in your steering wheel..
