Strano Performance Parts Lowering Spring sets are officially on sale. A second shipment is due in here next week, we've found the ride heights and fitment to be just what was intended. So they will not be available to the general public.

The all important details:

Price: $269 shipped

Lowering amount: Approximately 1.25-1.3" (result vary from car to car, but all have been consistently in that range as was intended.

Spring rate: 550 lb/in. linear rate front. 100/150 lb/in. dual-stage rear. The dual stage is needed to keep the spring from coming loose in droop. the working rate is only 150 lbs/in. and it's very obvious the softer portion is immediately non-working when the car is on the ground.

Other details: I did all the specification work on these springs. The rates, the amount of lowering are all mine. These are NOT just rebranded springs. I don't have spring equipment, so I can't make them. The company building these for me is Vogtland.
Vogtland has pretty much taken over the market in some big racing series which tells you the springs are not crap.

My springs use Vogtland's proprietary VVS alloy which is 35% lighter than the normal spring steel. A set of Strano Peformance Parts springs boxed is 28 pounds. A set of anything else, Hotchkis, Eibach, etc.... is around 40-44 pounds depending on the actual spring set.

And here are some comments gather from the testers so far:

"I wanted to chime in about the drag racing capability.
I ran a personal best today with strano springs and koni SA's.
12.1 @ 118, 1.91 60'. "

"Stance looks perfect.
Ride is firm.
Turns great.
Springs = great product."

"The ride height data:
Before with LCA brackets, UMI APHR, 275/35 18 front 295/35 18 rear, stock
springs and struts/shocks, stock control arms.
LF: 27 1/2
LR: 28 5/8
RF: 27 1/2
RR: 28 1/2

After:
LF: 26 5/16
LR: 27 1/4
RF: 26 5/16
RR: 27 1/8

Total drop so far:
F: 1 3/16
R: 1 3/8
The springs stay put at full droop too."

"Got the Konis and springs on the car, Sam you have mail! I am very happy with the ride height / handling of the car so far. Thanks for the help Sam!"

 

So you taunt us with these new springs then say "they will not be available to the general public"? How much do these change the ride quality over stock?

 

They *are* available (will be the shipment is on the way), it was a typo.

Ride, these are handling springs first and foremost. Ride is actually quite good when proper dampers are used with them.

 

I take it these springs were engineered to work with your bilstein revalves, yes?

 

It depends on what I revalved the shocks for in the first place, and what valving I used. Revalves are not all the the same. But yes, we can use Revalves with them. Either new ones for these springs, or if they were valved for springs of similar rates (and not all springs are).

 

would these alleviate the leaning ride height issue that some of up eibach users have? just wondering if you have any expericance with this and whether it would be better to get differant ride height springs to compensate. what torque arm would you rec. with that rear spring rate? also, are they good with the koni sa/ third gen combo a lot of people get from you?

 

Leaning is generally not the springs. If you think it's the springs, it's easy enough to swap them side to side and see if the lean changes. Never does, which means it is the car (spring perch on axle, spring pocket, orientation of the isolator, thickness of the isolator, etc.).
