so i took my car a place to get my tires rotated and the spring in the passenger rear side was shifted out of place and the guy reccomended upgrading them cuz the car is high performance, so i am jsut wondering if i should upgrade only springs or bother springs and shocks throughout the car cuz the shocks keeop squeeking and such and also wat are some good companies to look into?
thanks

 

You have to know what you want out of your car. I would not change springs just because some tire guy said I should.

If the car is stock and used as a daily driver, than I wouldnt change springs unless you want to lower it.

 

well the only thing is that they are making a noise while i drive and i do not know wat it is like sometimes when i downshift it makes like a creaking noise or something.

 

Could also be your shocks squeeking if your car has a lot of miles, check out www.slponline.com i know they used to have sets of stock shock and springs for 50 each.
