how far up in the threads are you guys running your collars. I'm about 4 1/2 inches from where the threads start and my car still sits REALLY low. Do I need to add a heavier spring? I bought these used and I can't remember what weight came with them. I have taken off about 100 pounds off the front of the car and i'll be doing a tubular k-member, skinnies and a little bit lighter brake rotor up front. reccomendations?

 

The skinnies and brake rotors are not going to affect the springs. They are supported by the tires and not the chassis/springs. If you're using a soft drag spring, you'll probably find that the car will compress it quite far (which would require you to run the collars up the shocks a considerable amount to keep the nose up). I don't have any hands on experience with that combo, but what you say sounds quite reasonable due to the nature of drag springs and their rates.

 

any more ideas?
