So i just finished putting my H&R sport kit on my ss/sc and now when i drive and accelerate, i feel a lot of vibration in the front... but its only when i accelerate.. If im just cruising i cant feel it at all. I got it aligned to almost perfect.
Would it be because i have my 16'' snow tires on? Could they be un-balanced?
Im freaking out so any input would be amazing!


AND BTW
HAPPY NEW YEAR!!

 

It's because you lowered the crap out of it. Mine rides rough as ****. Lol.

 

Did you get an alignment yet??

 

https://www.cobaltss.net/forums/suspension-67/ok-so-i-think-i-might-have-figured-out-lowering-springs-vibration-issue-84325/ read that.

 

u have to align it after u lower any car dude

 

he said he had it aligned

 

There is a difference between a car riding rough and vibrations in the wheel/pedals. Which are you having? It's pretty normal for a car that is dropped 4inches + to have a really rough ride. However, you shouldn't be having any vibrations. Does the car pull at all to the left or right while coasting? If so, it's possible that it could be your alignment. Other then that, I really don't know, but I hope it all works out for you.

 

I have the same drop kit i love it but its just a little rough riding. well compared to a truck or something like that, but it should be your alignment or you majorly F***** up on your install.

 

just remember you changed the suspension geometry. the axles are probably binding a little bit. mine does it with sportlines

 

sry to thread jack! but i have a real quick question bout springs. will i need a spring compressor to get my drop springs on??

 

Search the how to section...good info on lowering your car....

 

if u did it yourself are u sure u put the front on the front and the rear on the rear?? i know probably sounds like a stupid question but! could be a possibility!...hope it works out for ya!! i never had any problem when i dropped my cavy

 

thats not even possible. the springs are completely different

 

FAIL. he said he did lol

I jusst put sportlines on yesterday and i know the vibrations your talking about...it is becuase you firmed up the car...just like when you put new mounts on the engine and tranny your stiffening ur ride characteristics so you will feel more of what the car is doing including engine vibrations...no worries though all is well for you =)

 

im sure its not engine vibrations... it feels like the tires vibrating when i accelerate... i got the alignment, and yes i put the springs on right. This is the third car ive done my own suspension on. im not some new kid on the block here. this is however my first set of snow tires( blizzacks ), so i was just wondering if thats what it could be... its a very weird vibration.

 

did you read this post ddss?

 

the axle angle is quite harsh when you lower our cars, it will cause a lot of on throttle vibration. the only way to correct this is by using OTT performance rotated engine mounts. basicly they rotate the motor forward raising the diff to correct the driveline angle.

 

mine does that same thing you can join the lowered and vibe club!

 

so its normal? how much do those mounts cost?

i just dont understand. i have been researching lowering springs and i never heard anything about this
