i just installed k sport coilovers with ottp stage 2 trans mounts and steering rack spacers and i get vibs from 55-70mph i have got an alignment but still has not fixed it

 

bump

 

make sure your subframe and tranny mount bolts are tight. I once had vibrations from the subframe bolt coming lose.

 

id say probably one or both engine mount might need to be replaced, if they are stock probably too mushy compared to the stage 2 and just eating the vibes. im currently trying to cure vibes now in second gear. waiting for my lnf rear mount. also iv you are on coilovers super low you might run into axle bind. try raising it a little and see if you feel a difference.

 

i didnt losen up the motor mounts when i installed the trans mounts but i had the coils low and raised it a bit and i dont think it is axle bind because i would get it at low speeds and it rides smooth below 55

 

you might wanna loosen up the passenger motor mount and retight it because my mount roated my engine a bit to aligne the axles.

 

i did that and still no fix. Sometimes it will vibrate and sometimes it wont

 

hummm. i was reading on this subject for the longest time, they say if you feel under accel, its the axles, if you feel it un a certain rpm range its the moutns, if you feel like at high speed its wheel balance.. id still check to see if your motor mount moved when you unscrewed the scews.

could be an out of round tire maybe?

 

i believe it would be the tires. for one the people that mounted the tires to the rims and balance were new and probably didnt know much. Plus if i let off the gas and change gears to say like 5th it goes away until i engage the clutch again;

 

if it was the tire clutch engage or disengaged wouldnt change the vibration

 

seems when i let out of the gas, vibration beings to get stronger

 

im waiting to replace my rear trans mount on monday ill let you know if mine was fixed.

for your problem, on the passenger side the axle is longer and it has a bearing to support it did you take a look at that bearing? mine was completly out of the bracket.

 

no i didnt

 

i found another post and the guy decribd the same issue and he found that the nut holding the axle was loose got that torqued and it was solved so im gonna take a look at that also

 

my lnf rear mount did help a little but still having a little bit of vibration im going to take off my fusebox to inspect my top mount to see if its damaged or neexds to be replaced
