I have never been a granatelli fan but will have to say the experience I had with a friends car was one of the more pleasant dealings I have had with any company.
The car had a problem with killing UCA bushings in the rear, replace with urethane and same issue, tossed the stockers back on and it was fine. Placed a call to GMS and recieved a call back within the hour thanking me for calling and informing me that they had found an issue with the control arms have fixxed it on the newer ones and will be shipping new arms with delrin bushings as well as cover any labor he would be charged to swap them out.
