racerx Posted March 24, 2013 Report Share Posted March 24, 2013 will these lower the height of car and do you know lbs.? Link to comment
datzenmike Posted March 24, 2013 Report Share Posted March 24, 2013 Stock pounds per inch would be near 350 to match the front stock strut spring's 90 pounds per inch.. Link to comment
MARS 510 Posted March 24, 2013 Author Report Share Posted March 24, 2013 will these lower the height of car and do you know lbs.? Honestly I don't know the stock height of the car. I just measure these springs and they are about 9 3/4" high Link to comment
datzenmike Posted March 26, 2013 Report Share Posted March 26, 2013 Just checked the Realm. Rear spring rate is 357.2 pounds per inch so I was close. However my calculations show this spring to be over 500 pounds per inch. Free length might be closer to 12" so I'm waiting to hear back from them. Can you measure the thickness of the wire and the distance across from outside to outside? This may be a lowering spring which is also stiffer. Link to comment

datzenmike Posted April 13, 2013 Report Share Posted April 13, 2013 ok here are the measurement of the spring, hope this helps. Looks like 1/2" thick but parallax on the width... maybe 5 3/4"??? Height does not matter but number of active coils does... looks like 6 (spring constant of steel) 11,250,000 x (wire thickness to the forth) / over 8 x (number of coils) x (coil diameter to the third) 11,250,000 X .0625 / 8 x 6 x 144.703 703,125 / 6945.75 = 101.23 pounds per inch Something wrong here. The 510 rear coils are only about 4 1/2" across yours are almost 6". The rear coils need a constant of around 350- 400 pounds per inch. 101 is way too light. Link to comment

Cruz when I got my 510 the guy gave extra parts for it so I figured those were 510 rear springs. Link to comment
