Front end lifts

[m3f_armorrig]

Feels like my front end/engine lifts slightly when I apply throttle in lower gears.



It feels similar as before when I had a crack in my driver side motor mount on the subframe. I bought a used subframe and had the reinforcements welded in and it felt more solid after. Lately, before I did a front suspension refresh, it started feeling the same as before. Took care of some front axle bits thinking that it'll solve it somehow, but it still feels the same.



I rechecked front axle yesterday. Everything looks good and bolts and nuts are all tight/torqued.



Would a worn strut hat cause the front end to feel like it slightly lifts up when you drive from a stop or to 2nd? ex: I drive in 1st, let off the gas pedal, then apply gas, if feels like the torque causes my front end to slightly lift.



Any input would be appreciated. Thanks.



Rundown of newly installed items for front axle:

FCA and FCAB(OEM offset)

Tie Rod ends

Struts (h&r coils)

Installed a used front turner sway bar with adjustable endlinks



new OEM motor mounts installed last August, replaced subframe and welded reinforcements

This is the natural motion of the chassis....

Are you sure it's your front end lifting and not your rear end squatting?

I would think that it's normal. But it actually feels more like bucking but only doing it when you apply throttle after letting off the gas and letting the car roll.

I'm pretty sure it's the front end as I can feel it and kind of see the front lift up.



Feels as if the car has a lot of torque wherein when you step on the gas in 1st gear you get pushed back on your seat, but only it seems the engine/front end is what's getting pushed back and not me.



What are the other mounting points of the engine? It felt like this before as well even after the new subframe and new motor mounts, but I discovered that one of the bottom nut on the driver motor mount came off completely. Replaced that and torqued all motor mount nuts to spec. Somehow after that, the motion never went away anymore.

Check your transmission mounts too.

How old are your shocks?

How old are your shocks?

Big +1



I know what you're talking about. I replaced my shocks (sachs) and I no longer get this sensation.

I just replaced them with AKG 80a, but it didn't solve the issue. My OEM motor mounts are 4 months old.

My struts are 4 months old. H&R coilover.

[m3f_BleedsBlue]

Rear struts also 4mo old?

[m3f_tectonic]

Did you replace the RTABs? Sounds like they are worn out.

[m3f_armorrig]

Rear struts also 4mo old?

Yes. Installed as a new kit.

It has a TMS racing rtab. Reinforcement also welded in on the RTA pocket. I might switch it out to some UUC RTABs I have laying around.



ps: Interior/seats from your avatar looks very nice!

feels like that... but not as high though!



Imagine the saying, "Vtec, just kicked in yo" it feels more like that...

Did this problem exist before the coilover install, come into play WITH the install, or X amount of time AFTER the install?


Lifting of the front end (and consequently squatting of the rear) is normal when you accelerate, for any car. So i'm assuming it's excessive enough to warrant worrying about it.


Movement of the car has to do with the suspension. Driveline components don't greatly affect how much squat the car has on acceleration.


What are the spring rates and shock settings you're running? Front and rear ride heights? Tires and pressures (you didn't recently switch to snow tires and notice this start happenning, did you)?
