I really wonder how those springs would do on a gen3 wagon...
I currently have gen4 Sedan struts and springs in back and i can assure you .... its hell (lol @ my free lowering springs
)
My dad threw the good stock springs away ... they were MASSIVE.. easily 1.5 times bigger in diameter to compensate for weight difference in wagons.
How rigid are the TRD springs and how would they react on a 3300 pound wagon whose weight distribution is totally different...
