have a set of strange coil overs that came on my car, i believe they are 10 way adjustable struts, I do not know the spring rates exactly but this car was setup for serious drag racing, im guessing in the 175-200 lb range. they are used but not much. previous owner installed them in 07 from the receipts car got parked in 2010 he bought it with 14k on it according to car fax and it has 24 on it now so less than 10 k just by obvious math but I dont really know the mileage. id like to trade for a clean pair of fact bilsteins from a cobra coupe or a pair of hds for a new edge car. id sell them outright for 300 plus the ride and paypal. I can text pics, theyre still on the car pm or email [email protected] thsnks
