I purchased a 91 RX7 Convertible last year with only 57k miles. The shocks were original and needed to be replaced. Well in doing so I got a little over ambitious and also changed out all the Coil Springs all around. However, the only ones I could find lowered the car an inch. I've used it that way for the past 9 months and really want to go back to the stock height. I have the original front Coils, but cant seem to find anywhere to purchase OEM replacements.

Can anyone help point me in the right direction?

 

Mazdatrix carries them.
$135 each

 

any Mazda dealer will sell you FC33-28-011 for $150 each.
