New suspension installed - now have a bigger arch gap
Discussion
Hi all, could do with a bit of advice. Last Sunday I installed new shocks, Springs and top mounts with bearings on my 2010 C30 2.0d. I was happy with the ride height but wanted New suspension at the front having previously done the drop links and wishbones. However after installing I was left with about a 1cm or so bigger arch gap and its been this way all week now having driven it for around 80 miles or so. Can I expect this to settle as I purchased the correct shocks/springs/top mounts for my model. Any help is appreciated

If installed totally correct they will settle some but shouldn’t all. You will probably find over the same lifetime as the last parts it might reach similar. I am alright Jack said:

This, and did you tighten things up with the weight on the wheels rather than with the car on a jack/stands etc.joropug said:
Perhaps your old ones were saggier due to age and the newer ones are the proper ride height.
That thought did cross my mind, I've had the car for 3 years and never done the front suspension on it and there's no recollection of it in the receipts and it's done nearly 80k now, that was part of the reason why I wanted to do themI am alright Jack said:

If you tighten up with the suspension hanging down on a jack you may well find the car is higher than normal and the new bushes are overloaded.

Ah I see, I'm assuming the final tightening process applies if your using a socket set or an impact gun. Would it work if I was to jack the car up, loosen off the top mount bolts then lower the car back to the floor then tighten up or is it too late for that now considering I've done roughly 100 miles on them?Final tightening should be done with the car on its wheels & a few compressions (a few bounces on the suspension or drive a short distance) to allow bushes to take their correct normal positions.
