Good morning all,

Hope all is well with everyone. I have a dumb question, so I had the privilege of driving a 2021 Corolla XSE 6spd manual, such a very cool car, so love what Toyota has done. What I noticed was how comfortable the ride was on that Corolla. I was wondering how could I find out, if possible, if the springs from the Corolla fir the CT? The corolla sits higher than the CT but I know that can be corrected. I just really love the soft ride.. Any thoughts?

Thanks in advance..

The wheelbase, body-in-white/torsional rigidity (TNGA), weight and general needs of both cars are different so even if the suspension could fit, it would be a very poor choice. Spring and damper combos are highly tuned for a specific suspension setup. Different suspension types have different "leverage points" so a spring or damper set up for a 1:1 motion would be very different if the spring or damper was further in or outboard than the car you are taking the part from. Also, a TNGA sedan would have much higher torsional rigidity vs a CT so if you could swap, you'd have a severely underdampened and undersprung CT which could be dangerous. The body of a car can and does act as a second "suspension system." so that's always taken into consideration. the stronger a body is, the softer you can spring and damp a car to retain the same ride quality. This is why strong bodies=comfortable rides. the engineers know what they're doing when spec'ing equipment for a certain operating envelope.

So in other words, leave it alone. lol.

at most, you could likely swap from a scion TC but might find yourself spinning your wheels (no pun intended) as they could very well be tuned similarly.

 

WOW thank you so much. So very helpful... I will just leave well enough alone.... Makes a lot of sense. Thanks again.

 

Yeah the CT is just inherently a very stiff riding car. A lot of it has to do with the short wheelbase. a 2020 corolla has a wheelbase that's a full 4 inches longer. that alone aside from anything else will equal a more comfortable ride.
