I have a 1990 hatchback with a 347 pushing about 450rwhp and I keep breaking my passenger side upper control arm mount on the car. I have all tubular adjustable control arms, subframes, gas adjust shocks, and 275 nitto 555 tires. I want to eliminate the uppers and ive heard you can use a torque arm kit such as this http://www.maximummotorsports.com/s...ge=product_info&cPath=1_5_504&products_id=346 or you can use a coil over shock kit with a panhard bar. is this true or are there other ways of fixing my problem? what are the pros and cons of the systems such as ease of installation, grip, drawbacks, etc?
