Den bakre hjulupphängningen på Model 3 är monterat med gummibussningar. Dessa gummibussningar är ganska fasta, men de tillåter fortfarande en liten rörelse av hela den bakre hjälpramen under tung belastning vid kurvtagning. Även om detta inte orsakar en förskjutning av den totala vinkeln på toe, kan det orsaka en förändring i dragvinkeln och möjliggör en viss rörelse i sidled av hela hjälpramen. Med insatser från Mountain Pass Performance uppnås en stabilare och fastare konstruktion som möjliggör en hårdare körning på bana. Här nedan följer Mountain Pass performances egna ord: Description The Model 3 rear subframe, which all the suspension arms connect to, is mounted to the chassis with rubber bushings. These rubber bushings are quite firm, but it still allow some slight movement of the entire rear subframe under heavy loading. While this does not cause a shift in total toe, it can cause a change in thrust angle amd allows for some lateral movement of the entire subframe during cornering. This causes a disconnection between the driver’s understanding of the rear tire grip. Is the tire sliding, or did the entire rear subframe just move under me a little bit? Our Model 3 subframe inserts help improve that connection your brain has to the tire. We’ve been meaning to develop subframe inserts since 2018, when Tesla switched the very early production cars from solid subframe bushings to rubber. As you might imagine, Tesla did this to reduce noise in the car. So you should know that there is a slight increase to NVH with this part – mostly just some additional noise coming through from the rear of the car. It’s relatively minor, but it’s worth pointing out.
