Haz l33t wheelz.
mr. specific strikes again, haha.
but on a serious note, it would be nice to compile a thread with all the spring rates of available lowering/performance springs including the stock ones for comparison by those that know what they're looking at.
also, to say whether or not it is a progressive rate spring would be good. Help correct the "rides nicer" aspect with real numbers?

As far as progressive or not, thats pretty easy....if its a straight coil its a damn good chance its linear rate, really only Ground Control coil sleeves and some coilover kits are like this, I know of no spring kits that are.

Suspension
–
Stiffer Springs
•
20% increase front, 30% increase rear
–
Larger front and rear stabilizer bars
•
24mm front (22mm base), 24mm rear (22mm base)
–
Increased Damping
–
New Knuckle design
•
Short steer arm
•
Raised roll center height
•
Increased durability for track abuse (bearing and casting)
Steering
–
Quicker 14.8:1 ratio (from 16.5)
•
Short steer arm knuckle and higher C –factor rack
–
Increased EPS Steering Capacity
•
61Amp brushed system for more power (58Amp on base)
By the way Mark Wilkins young Grand Am Rolex Daytona Prototype driving ace, tested the Balt TC yesterday at Mosport race track, first stock and then with modded suspension by OTTP :cabs, and rear bars, AND declared the car great to drive with the changes. Mark wanted the 1.25 bar and another day with sticky tires it was so much fun.
Owner Rob himself a competent noobie racer, found the car much more stable at high speed with the 1.0 bar, preffering that set up for raod racing, and then took home both as he thought quite correctly that the 1.25 will work very well in tight slow corners in AutoX. Get these parts at OTTP..
P/N: 3898.140
Eibach Pro Kit for the Saturn Ion
It will lower the Redline by 1" in the front and 1.2" in the rear.
It will lower a base Ion by 1.4" front and 1.6" rear.
Front Spring
Main rate = 177 lb/in (31 N/mm)
Initial rate (installed) = 143 lb/in (25 N/mm)
Free length = 282mm
Rate transition length = 173mm
Installed length = 148mm @ 3500 N
Rear Spring
Main rate = 126 lb/in (22 N/mm)
Initial rate (installed) = 63 lb/in (11 N/mm)
Free length = 306mm
Rate transition length = 179mm
Installed length = 154mm @ 1950 N
Pedders springs are better...
