The new 2021 Tesla Model S and X use completely new control arms.  So our SX-1 adjustable camber arms and our TSX-1 adjustable toe arms will not fit the 2021 versions.  We do have lowering links that will fit the 2021 refreshed Tesla S and X.  They are different than our original lowering links for the 2012 to 2020 years.    We are also working on designing new parts for the 2021 Plaid and non-Plaid versions now.  Check back soon...
