Lowering springs

How does one feel about these...?

I've had a lot of different spring manufacturers and have always come back to eibachs. Springs are an integral part of your suspension..things like compression rates/rebound etc aren't to be taken lightly. There's a reason why eibachs or a quality manufacturer are $320 +/-. Personally i wouldn't buy these, i've had cheap ones that didn't site in the perch index 100% due to what appears to be quality..up to you.

I agree. These f-bodies dont have the smoothest ride to begin with. I personally like BMR, but eibach pros, or stranos, are what everyone in most cases are using. Also the ride quilty gets alittle better with them as well.

350F & 250R spring rate...

so they lower the car 1.3" and barely add any rate up front (softer than a factory 1le spring) yet more than double the rate in the rear (to beyond almost any name brand spring for these cars)

I personally like a spring rate on the softer side for the rear of these cars, after numerous sets of springs. Here's a list of some rates just to give you an idea, my experience has been that linear springs ride nicer and feel more predictable in general over progressive springs

For the $45 that I spent on them, I will give the fronts a shot and probably just do the hose mod in the rear...

The problem is 250 for the rear spring rate it too much for a f body with a stock rear roll height. Chances are the car will oversteer pretty bad with that setup.

Not a bad deal, but sometimes the cheaper springs end up with a more extreme drop than what is advertised, and/or sag over time. Also only adding 50# of rate probably won't compensate for the reduced travel, so you'll be hitting the stops more, but it will probably still ride pretty decent.

then again for $45 less than $45 you could have cut a coil from the stock spring, which by the equation...

k = (G*d^4)/(64*R^3*N)

k = spring rate
G = modulus of elasticity (material property)
d = wire diameter
R = mean radius of helix
N = number of coils

...would have yielded a spring rate in the 340 range anyway

either way, post pictures of the drop when done and do a review!

I bought the Bilstein kit. Came with Eibach springs that lowered the car 1". I also replaced all the chasis components. That kit is one of the best for the money. Car rides like New again.

Possibly. And a slew of other things as well.

Nice. I would've stopped by but I was running late to work.

I went through Eibach, and Hotchkis with adustable shocks were really bad when hitting bumps. The car sounded like it was going to rock apart. The Stranos springs were my last ones and I absolutely loved them but the car was just too low and damaging everything underneath. I have the SLP springs now which raised the car but I am just not happy with the new handling as the stranos and AGX shocks really kept the car grounded. I think I will change to new shocks to see if that improves it.

Im running big headers, and my turbo piping runs below as well. And if I switch to a Supercharger that also runs underneath also. I put a spike right through my header last year. I have all new equipment now and not chancing destroying it all. If you have all factory underneath then there isnt much to worry about.

How low are you wanting to go? I have the SLP level II springs, they dropped the car about 3/4".
