Hey guys i had a question. im running tokico blues with lowering springs right now it came with the car when i bought it, and was thinking to swap out the springs for some ground control sleeves to slam the car, but im wondeering if i can use the same sleeve for koni yellows after the tokico's blow. Cause i heard there are special springs for koni yellows. Please let me know, thanks for your guys help.

 

it's not the springs that are special, its the sleeve that is made for the koni yellow's.
