So I've checked out this Moog spring chart that's been floating around and was looking for some input on front coil springs. http://jeffd.50megs.com/Moog_Spring_Page.htm
The last 3 G bodies I owned had f41 springs in the front and with or without knuckles in the coils they sat nicely and rode nicely. Fast forward to my camino now it had super saggy springs that looked dropped when I got it. I have replaced the shocks and that didn't help much, but I've put some twist in knuckles in and it sits better but not even as high as my 87 without knuckles. The springs are shot!

I want the front raked up and don't want to run knuckles, also don't want ridiculous "lift kit" springs tweaking out the geometry up front. Any recommendations would be great, thanks.

All depends on how high you actually want it to sit, stock lower than stock or higher than stock height. And how heavy the front of the car is will dictate how it sits with a given set of springs. Is it a v6 a small block a big block ect. Whether it has weight saving items like aluminum heads a glass hood ect also makes a difference. With a typical iron headed small block Chevy and all steel panels and bumpers and such a 5608 should net you a stock ride height. Where the same setup with a 5610 spring will probably get you higher than stock.

305 sbc iron heads, a/c and heater delete.

I did notice a slight increase in height when I swapped aluminum heads on my last cutlass.

I'm gonna guess she weighs about 1,100 - 1,200 lbs per corner up front. What springs do you have out back? What tires, and are they the same all around? Also, what shocks? I've put together a couple of lists for myself that have more choices than the one from Malibu Racing that we're all familiar with. I'd be happy to look into it.

Factory springs out back, 165/80/15 up front and 235/60/15 in the back. KYB 343127 front and 343157 Excel-G rear shocks. Much appreciated

Some before, in between, and after(knuckles), and my cutlass with the similar wheel tire combo... I really liked that stance(f41 suspension with some twist in knuckles and cheap gabriel shocks.

I fell asleep eating dinner last night so I'll have to find my lists after work tonight. I agree that the 5608 or 5610 would probably suit your needs (stance) when paired with the saggy old springs out back.

if you're sure the springs up front are the oe stockers then a new set spec'd for a v8-a/c car should sit higher than it does now because over time thing's sag by default.global west makes solid drop in spacers that go under the spring that won't effect ride quailty compared to a twist in style spacing.the return's usually pretty good one on them at about 50 percent over the size of the spacer too.
