I would increase spring rate a little bit. the 450s seem a little stressed, but work well for me and I've got an LS with some composites and aluminum on the front end. If I added anymore weight, I would increase spring rate a little, especially if you plan on running 200 or less treadwear tires. With the additional 75ish (or more) pounds from the supercharger, I would start to worry about getting a little bit of coil bind, especially if you're using half height body mounts.

How much to increase spring rate is the question though. I would research what Stielow is using in Red Devil, for a starting point.

*edit* we've also just been assuming that you bought double adjustable shocks, but I'm not quite sure how relevant that is to your original question.

that makes sense to me I was hoping some one had been there done that but being that every body' car is a bit different one way or the other I guess I will have to wait to finish it, drive it , let it settle and take from there.
very well said JSM. im sure when time comes other factors will come into play

Not sure, and correct me if I am wrong......but everything I have ever known/heard......coil springs should be 99% primarily used to obtain correct ride height:thumbsup: ? If additional weight is being placed in the engine compartment than car will sit lower and will have the shock in a not so ideal compressed position and will suffer from minimal compression travel. By adjusting the shock valving you will only stiffen the shock and will still suffer from minimal compressed shock travel and will not be ideal. I suggest increasing spring rate to support car height as needed putting shock in sweet spot so you have necessary compression/rebound.

In this instance, it's a coil over so ride height is adjusgtable to keep the shock in it's sweet spot. Howver, coil bind is possible with to much pre load.

Very true Vegas69, in my opinion though ride height should only be "fine tuned" with this adjustment and never used to compensate for incorrect spring rate IF that be the case, since as you mentioned.....coil bind is possible when trying to achieve higher ride heights/compensating for extra weight using the threaded shock collar to bind coil. To many variables to diagnose over the web.....but most likely a slightly heavier spring rate will be needed for perfection! Good luck :thumbsup:
