Would putting lowering springs on my car really change the tightness of the suspension?

 

Any springs you buy that aren't OEM will strain the factory struts....it's just a quick fix till you have $$ to get a full strut/spring system or coils....

The ride will get stiffer depending on your drop and that due to the change of compression on the OEM strut...they will eventually go out....The lower the drop the quicker they will go..

I've had S-techs for 2 years/20k miles with no problems yet...S-techs are the lowest drop you could get (99% positive about that)
hope that helps....oh and for more info, do some research!

 

The best two upgrades that we have found are the TRD Springs and TRD Rear Sway Bar when you factor in the improved handling and the dollars involved. The two together will completely change your handling. The stock shocks will hold up with the TRD Springs past the warranty period in case you don't want to change them yet. I would not drive another car without those two upgrades.
