Just the front springs?
Do you care how firm or soft they are?
You WILL need to match the front jounce frequency to the rear's, or you will have a real handful, upon hitting dips & bumps on the highways.
I've got a fairly comprehensive list of whats available, compiled within the past 4 months, as the landscape is changing all the time.
Presently, Eibachs are no longer made in Germany.
I ended up buying a complete matched set of four Canuck 1.5" lowering springs, $205 delivered.
You can buy just fronts in Moog, but you better know your rear spring rate, and most importantly know how to balance your front to rear spring rates properly for safety, performance & comfort.
If you go that route, I will help you decide which rate and installed height to select.
