Install a Sway Bar
If your car leans too much through turns, all that weight transfer and body roll will kill your handling. Sway bars help keep that in check by connecting the right-side wheels with the left-side wheels, helping the car corner flat. All the once-wasted kinetic energy is focused back into getting the car around the turn more efficiently. You can buy one for around $500 dollars.
Install a Short Shifter
Short shifters are a pure performance add-on. They minimize the distance the shifter has to travel, and thus, the time it takes in to select the next gear. That said, when you can quickly click through the gears, driving a fun, fast car will feel that much better when you’re carving up a canyon road. uyou can buy one for around $300 dollars.
