Which one should I get?

The one for the Supra N/A which drops the car 1.3" front and 1" rear

or the one for tha Supra TT which drops the car 1.2" front and 1" rear

Is the spring rate gonna be different for either one? I do plan on going turbo in the future.

 

FYI: The Supra N/A eibach prokit is discontinued.

Here are some before and after pictures of a TT setup: https://www.clublexus.com/forums/sho...supra+bilstein
The supra TT eibach drop looks perfect.

Also, use the Search button. You can learn a lot from it....

 

some online stores still them. But I like the TT set up too.
