2005 prius base model suspension upgrade ------2006 prius touring suspension

I don't kn0w if you would consider the "Touring" version to be smoother riding than the non touring. My understanding is that the suspension is actually firmer and tuned more for feel of the road so to speak. I haven't driven a touring model, so I cannot speak from personal experience. But everything I have read leads me to believe that the ride would not be smoother than the non touring models.

FWIW, anything is possible if you have enough money to spend on it. The real question is "Is it worth the cost thereof?" It would be more logical to purchase a touring model than try to convert a non touring into touring.

 

If you replace the front struts and rear shocks, I believe you will feel a reasonable improvement.

 

Prius's ride rather harsh imho. If its your only car you may not notice it after a while but if you bounce between different cars like I do the Prius hits hard. Tight little car. Short wheelbase. Tiny little suspension parts up front. Not alot of mass up front.

The Prius is all tire. Make sure your not running the original type of tire that came with the car the GoodYear Integrities which are possibly one of the worst tires ever made. They hit hard and ride loud. If your running those get them off asap and the ride will improve 100%. I have good luck with non lrr Kumho's.

If your looking for more ride comfort more than hyper mileage replace them with a non LRR tire like I have. Sidewalls are softer. You will take a 3 mpg hit but so what. Your saving the suspension. And the hyperinflation of the tires for better mileage makes the tires hit much harder and will pass all jounce and impact right to the chassis. Struts take a beating and so will the rest of the car.
To save what?.......$100 a year? My car has no squeeks, rattles, clunks.

And lastly deflate the new tires a little. Try running them at 34-33 pounds or at door placard
pressure.

Also Touring suspension is tighter than stock. Forget that.

 

FYI

The touring model wasn't available until 2007

 

Yes, it is possible and I did it with my Ema. My wife had a 2007 Touring and it rode noticeably better than Ema. Part of that may have been the 16" tires on the Touring but part of it was suspension. When Ema needed new suspension I upgraded her and have not been disappointed. Here is an old old list of mine for parts. Not sure how many of these part#'s are still good but somone (Patrick) may be able to help with that.

Just got Front strut bar and new front struts. Springs were $150 from Dealer so I got them as well.
Front Strut bar was: Tanabe TTB151F Sustec Front Tower Bar ($100)

It rides so nice and smooth! Very happy.
