So this was why those Summit control arms were so cheap

nothing like spending big mone on the motor and buying the cheapest suspension parts possible.

If the control arm didnt break im sure the bushing would have torn apart after time
 
The notes are listed on the web page and in the instructions. He should have read them.

And....?

"Not designed for use on vehicles which will be drag raced with slicks. Recommended for applications under 400 Rear Wheel Horsepower."

As of right now, with no tune, I would bet his car isn't making over 400hp. He was on the street with street tires. Sounds to me like he read the instructions. :rolleyes:
 
Can't really fault him for giving them a shot but there's no way I'd put a revised version of the same pieces back on the car.

Were it me... I'd hold out for some much beefier replacements. Maybe take the replacement set that summit sends and put em on ebay to help off-set the cost of some MM or Steeda CAs.
