Just installed a set of GMG springs and 20 inch Champion wheels on Nitto Invo's on the 2009 TT...

She feels a bit "less" stable at higher speeds .... Hard to describe - maybe a floating sensation .... Do the springs need a few days to settle or ?

Wheels were balanced but I didn't do the alignment yet

Any suggestions appreciated ....

Thanks

It needs to be aligned after a spring install and that's likely the source of your sensation. I would do it quickly. 911s out of alignment chew up the rear tires insanely fast.

 

This. Had the same floating sensation while waiting for the car to settle a little before an alignment. Those tires just want it grab every angle of the road.
