Issues and first impressions on GV60P 18" new setup

[PasternakBoooris]

We finished our 18" new setup for my GV60P and wanted to share our experience. Got the TPMS from Amazon and had it mounted. The ride is way smoother and quieter than the stock 21s. Also, the car seems to be a bit more efficient now.

However, we noticed a decrease in braking performance. Anyone else downsized to 18s?

It should be the other way around if you have bigger sidewalls. Try having your tires aligned first and have it balanced.
