neeed help indentifying GC

i found a real good price on some Ground controls...

the seller says they are custom spring rates ...the exact ones i want 450f and 550r

is there a way i can verify that this truly is a custom spring rated ground controls and not some off the shelf rated ground controls

Have him take a picture of the springs showing the numbers printed on them.

Re: (gabebauman)

How do I tell what my spring rates are?
Ground Control sells Eibach Race Springs (ERS) which are labelled by 3 different values in the following convention: length . diameter . spring rate. However, ERS will come labelled in either Metric (mm.mm.N/m) or English (inchx100.inchx100.lbs/inch) units. 180.64.61 is the same thing as 700.250.350. The conversion from Metric to English is (/.254, /.254, x5.7) "/" means "divide by", "x" means "multiply by".

Tyson, that is an excellent link, btw. Good info in there.

It is interesting to see that H&R OE sports and Sport springs both have the same spring rate (276F/220R), just different amounts of lowering, .75" versus 1.75" respectively.
