Alright I been doing a lot of research on springs for my IS350 and I'm down to 2 springs Tanabe NF210 or Tein S. Tech. Please give me your input on which I should get.

 

What size wheels are you installing? I would get either the RSR Down Springs or Super Down. I've had Tein springs in the past and the ride quality is okay not great. I'm currently running RSR Half Down for my 20 inch wheels. Also, a majority of the CL members have RSR springs.

 

2nd rsr downs. i'm running them, and imo they have the perfect drop

 

I just got my ark performance gt-s lowering springs in yesterday. I'll chime back in when they get installed Saturday.

 

On RSR downs, on New York quality roads. Would definitely recommend

 

I'm running rsr downs on awd and the drop is gorgeous nearly everyday I get compliments on the stance of the car.

I'm running spacers on the stock wheels.
