Or is it the same for all three versions? If the do, where and with what?
Searched on this with no luck. Thanks.

Do Limited Models Have More Soundproofing?

This topic in various guises turns up for FJ's and Tacomas [which I ruled out years ago as being way too road-noisy]. I doubt the Limiteds have anything different specific to noise management. However, something I learned from digging the topic re: FJ's and Tacos is that some, or at least one, of the Regional distribution points do, or did, add undercarriage undercoating. IIRC it was the vehicles that were provided through the southern regional hub that might have such undercoating and that it DID provide some dampening re: road noise.
This came up because the same owner had two tacomas a few years apart, same generation, and one was significantly quieter. the only diff was how it was delivered, and the info was on the sticker.
wheel isolation, spring isolation, strut/shock isolation - and of course tire choices, all add up to affect the low-frequency road noise experienced inside the can. Look at the weight diff between say a Lexus LS and a Camry or Avalon. Much of that curb weight diff is in insulation inside and outside.

Since I am about to undertake suspension upgrade - mild upgrade to Bilstein 5100 series, and rotate the springs - I would like to know if there are "better ways" - better products - for bushings or spacers between the body/mount-points and the hardware. Can anyone enlighten me about this?
I also have an old Camry - 2004 SE model - with nearly 273K miles on it, and while it is really quiet on smooth roads, it is very noisy on rough ones. one thing I found out via forums with other owners interested in the topic - there is virtually no absorbent spacing at all between the struts and their mount points, so some of the guys took the DIY route to trying to provide a little cushioning there. Not sure which material ended up the winner, as we wouldn't know the deterioration rate until some miles have been racked up. Once the material starts to break down you end up with a worse noisemaker than if none had been used, since the junction would become unstable, leading to erratic metal-on-metal noises perhaps
