I assume this is posted in correct section. Dropped on BC coils with slite tuck. 19s on her now with 235/35/19 front and 275/30/19 rear..Continental DW summers. Went front stock 18s with Pilot AS3's. ..rims and rubber balanced with alignment but front doesn't feel as good anymore and feels non balanced.. (road force balance done)....seems as though the diffrence in rake now due to the 275/30/19 rear being smaller than the 255/40/18 has made me think this could be a problem.....have no clue and thus this post? Just doesn't feel as good...even went softer on the BCs front and rear and still same ....any info or help.would.be much appreciated gentlemen......if it's the rubber will switch but really can't understand this one..
