The Circuit Pro Coilovers feature a dual spring design which gives a more aggressive feel which may be commonly seen on fully threaded shock coilovers. Now you can have the features of a fully treaded shock without the big price tag. By offering the sleeve and spring portion of the coilover, you have the choice of your shock combo, whether it be an adjustable shock or regular high performance shocks. SPRINGS Cold Wound / High Tensile Chrome Silicon Steel / Spring Rate Pre-set / Stress relieved / Phosphate Treated / Powder Coated. ADJUSTMENT COLLAR AND NUTS Cold Forged High Density Aluminum / Stress Relieved / Phosphate Treated / Polished to High Sheen.

that's the description. i'm still confused-what exactly are they selling? is it the a coilover kit like the ground control ones or something different?

 

Yes. Appears to be exactly the same type of part as the Ground Controls.

 

I wouldn't waste your money if you're considering them. Just go for regular springs or a real coil-over suspension.

 

that's a sleeve-type coilover. imo the only sleeve-type worth spending money on is ground control. however, since there aren't any good adjustable aftermarket struts to pair them with, i'd suggest full coilovers.

 

cheap coilovers.go with the springs and struts set or the tein set

 

yea go with tein basics
