I switched to Falkens this time round, and had exactly the same thing. felt very light at the front and did not feel as confident in cornering.
After 500 or so miles it felt much better, I have done a good 2k since putting them on and now I don't notice any difference of feel when compared to the Bridgestones. I corner at the same speed with the same confidence as I did before
Maybe give it a few more miles
