Getting information on these springs is like pulling teeth...
I read a review on a Mustang install and spoke to a vendor and all comments were very positive. This is a quality product!
Spoke to an SC vendor but he didn't know spring rate, so I e-mailed Vogtland and will post info. when I get it. So I posted my questions on the technical forum.
You can read the replies @: http://www.sccoa.com/forums/showthread.php?t=102772
1" Vogtland: 315-412 front / 530-650 rear
1.6" Vogtland: 365-400 front / 600-713 rear
1.5" Eibachs: 286-411 front / 514-714 rear
1.5" Suspension Techniques: 432/631 Linear
From the measurements from those who have Vogtland, the drop on the 1" springs is right around 1" (maybe just under) and the 1.6 give the exact same drop as the Eibachs.
So what does this all mean?
The initial rates on both Vogtland springs is higher than the Eibachs. In my books, this is a good thing as I find the Eibachs a little mushy on smooth surfaces and because of that, the rate quickly climbs on sharp bumps. So IMO, based on these numbers and without having tested a car with Vogtland springs, both Vogtland springs should provide a better ride on rough surfaces. The 1" Vogtland should provide a ride quality very similar to stock while giving you the handling benefits of the drop.
Other factors to keep in mind:
- Good springs are only 1 part of the equation. Condition and quality of your shocks will also play a big role in ride quality and handling.
- Polyurethane spring isolators and sway bar bushings will give you better road feel and a tighter steering feel but will transmit some of the irregularities from the road. The density of the poly also varies, so not all are created equal.
- Larger sway bars will work similar to increasing spring rates without giving you such a harsh ride.
The rule that I like is "as soft as possible and as stiff as necessary".
It really depends what your expectations are and what you want to do with the car.
There appears to be allot of interest for these springs. Maybe we should set-up a group buy for our club. What is the procedure?
Hope this helps.
