I have surfed threw many IS300 forums and have not found a single car with Sprint 2in Lowering springs, which I plan to get when I get the doe. Are these of low quality? Any have any feed back at all about them? They can be found at http://www.nopionline.com/partdetail...oductID=468820 thanks

 

I have to state this at the very beginning, I don't have any personal experience w/the springs you described.

However, IMO the further away you get from the bigger spring manufacturers such as Eibach and H&R the more unknown the quality of the spring.

Eibach and H&R have long histories in motorsports and excellent reputations as spring manufacturers. They make quality products that are predictable in their results after installation.

I've heard of some 2" drop springs that finally settle w/closer to a 2.5" to 3" drop. The more obscure the company, the more unpredictable the result.

I have Eibachs on my car w/TRD adj. shocks and the drop was as advertised - 1" front and back.

 

No one with any experience?

 

I know a bunch of people with Sprint springs on Maximas, drop is more than H&Rs or Eibacks with ride quality falling in between the two

overall they are good springs, I'm not sure how it is on the IS but to prevent the rear end sagging, some people cut one coil in the front

overall good springs
