Poor-sha

Someone asked for the leaf spring part numbers for a car with the ZTK package. I pulled them off the car before the stickers wore off.

Front: 84020188
Rear: 23344290

thanks a lot for posting! do you mind to share bit info about how does the car ride compare to Z07?

Rear seems the same as the Z07 spring!

Great info, thanks.

I would really love to find out definitively what the differences are in spring/bar/downforce/MSRC tuning between a ZTK/non ZTK/Z07. My ZTK order is in purgatory for some reason, so I picked up a non ZTK to experiment with in the meantime....

any chance anyone knows the stiffness of the ZTK front spring VS a FE6 Z06? Thinking of swapping the springs onto my Z06 with the DSC controller

looks like I'll be the guinea pig and swap the springs/bushings. I am going to VIR in Nov 1-2 so it'll be a good test to see how it goes! I currently rub with slicks on the car so hoping that is resolved with a stiffer spring.

love to know if any one has tried this. I wanted to convert from FE6 to FE7 but am
unable to get the front spring anywhere.

part numbers above are for manual. Would those work on auto too ? Wonder what difference would be.
