Pretty sure EP91 springs on an EP82 will give it standard ride height. I bought a set of Teins which were for an EP91 but was assured they would fit the EP82. Now i'm stuck at the same ride height lol.
Recently brought it out of storage, haven't done much as I was in two minds whether or not to sell it. Should hopefully be at a show or two this year once i've tidied a few bits up :)
Strange but to be expected with a newish product. Only reason I bought mine was a step up from the aging PnP's, just giving that bit for flexibility. It's only gonna be so long before they start to fail lol.
They need to be tweaked to fit. I was after one many years ago and couldnt find one of the originals that fitted. You're better off going custom like I did. STG performance or CGR automotive come highly recommended.
