Not exactly. I made the swap to CJ's because the lowering springs i had, even with the d-specs dialed in fought against each other in the 60'. The front springs wouldn't allow the desired lift, and the rear would either squat too much or resist weight transfer due to the spring rate. Look up my vids on youtube of earlier runs this year, you'll see what i mean (PrototypexB). Went from 1.79 to 1.61 60's with the spring change. Also, the CJ's are very very streetable. I DD with them with no problemsFor the best of both worlds use a regular lowering spring and some Tokico D specs. On loose they will let you transfer like a mofo and on tight you can enjoy the on ramps on the way home....
