Should I do shocks and coils after 115kmiles?

    I’m around 115k on my 2012 Prius. I recently had my mechanic do most of what nutz and bolts posted and it appears that I need new pads and rotors. The Prius feels like I’m driving a go kart, I can feel every bump. Do you think it’s time to get new shocks and coils? If so, should it be cheaper if I get it done with rotors an pads?

    also, anything else besides shocks and coils… is there a kit that’s recommended or additional replacements recommended. Thanks a bunch.

    What tire pressures are you running? The higher the pressure, the harder the ride.

    FWIW I'd think there is little chance the coil springs have failed.
    I'd write, to be sure you have to remove the springs and measure static height.

    You may get any answers on the shocks.
    But at 115K, especially with your ride quality complaint, I would consider replacing.
    Without looking up prices, I could guess the part cost alone for the 2 struts and the 2 shocks at $400.
    To test shocks, many bench-test them cold and watch the rebound action.
    That's an issue, as cold shocks can pass rebound testing, to test you need to get the shocks hot.
    (ya ya ya x-racer who felt degradation every 5K miles and changed shock oil and recharged nitrogen)
    Of course, the "old school" way is to push down on a corner of the car and watch to porpoise-ing.

    Cost-saving to do at the same time, I guess $100 dollars, so a little.
    Not much cross labor is involved except tire removal.
    Maybe front caliper & rotor removal, but they may (may) swing out of the way for a strut change.
    Rear brakes I don't believe need to be removed to install the rear shocks.

    Good luck with your decision and improvements.

Not the GR series my coil springs are made out there near la where you california folks live by a custom spring maker they've made them for all my Toyota since my 73 SR5 corolla so I just keep using them great guy my piston maker is right up the street from him all of these guys are around trd's original location way back in the '80s early '90s the torrance area

    If you're blasting through your brakes in only 115k, then:
    Yes.

    You might as well do the shocks and coils too.
    Most people do not have to worry with such things until well after 150,000 miles.

    IF your car is being driven on unimproved roads, you use it for drivers-ed, OR you're not an especially...um.....'efficient' driver then you may expect to wear stuff out a little more quickly than the average bear.

    Good Luck!

    Same here: feels like go-kart. About 135kmiles on the clock. But annual inspection (required by law) wass a pass without any complaints whatsoever.

    Funny thing that my Honda (also high mileage and 6years older) feels smoother even though it’s a ”wanna-be-racer” and quite sharp handling.
