front spring weight recomendation Car is 3500 with out me. 3700 with me. Car has 6 point and still has ac, power steering, etc... The bumper supports and such are deleted. Car averages 1.40 60' on stock 150k front struts and intrax lowering springs. Car already has vikings on the rear. About to order front coil overs and would like input on front string rate.
I would probably recommend a 300 based on your weight and combo. It will give you a lowered stance and be light enough to freely transfer without being too soft

V6 Front springs are a 257lb rate, which is pretty soft for a v8 car. Not only will it be difficult to predict a ride height, but they will also be very soft for street driving and may cause an unstable feeling. Also, it will make your shocks work harder to control the extension of the front end if you get to the point where the car is pulling the tires. Too light of spring will transfer weight too fast and your shocks may not have enough rebound control to slow it enough to be smooth and controlled

Your 60' times are already impressive considering what you have on the front. Choosing the correct spring rates really is determined on what you are doing with the vehicle as much as it is the vehicles weight.
A street driven vehicle you will want to run a heavier spring than a vehicle that is drag race only. The nice thing about springs is they are not crazy expensive if you want to try a couple different rates.

The plan is a diet this winter. Would there even be a real benefit to swapping if the car is dead hooking? I'm talking I can throw what ever I want at it with no progressive anywhere the car goes. My concern is what will happen if I pull a bunch of weight. I can pull 150 lbs easily. Won't be out the front. Swapping to kirkeys and eliminating cat back for dumps. Don't want to delete AC/heat at this point.

[QUOTE=jblankenship;19457958] What you will most likely gain is 60' constancy with a good shock and spring package.

Update: Thought about it. I'm going pull the complete HVAC, cut what I can oit the front, light weight carpet, kirkeys, delete rear seat, swap steering wheel, pull the cat back off for dumps. Should be 250-300 LBS.
Still 300s? Some street time.

Good possibility but you won't know until you get a new weight.
I would still stay with a 300 if you plan on throwing more power at it and seeing street time. 275's are pretty light and can allow the front to extend too much too fast and put more effort on the extension of your shocks to keep it under control, or get into doing limiters. If you want large dramatic wheelies, then that would be the way to go. But if you want consistent fast launches, I wouldn't go too light with the springs

.... Would 275's fit on stock style shocks? No, the 275 springs are a 2.5" id coilover style spring and will not sit in the stock style locator

You can get close but some are past the point of doing things to be close.
I know I deal with it with my customers as well. People want advise without any details about the car or goals or what it's currently doing.... or worse they read on the interweb what to do with no knowledge of who's even telling them.
