Modifying front lower suspension arms etc
I have a Cobra front suspension design that is probably similar to most original style cobras, I want to shorten the lower front suspension arms, that is move the spindle inwards 3/4" so I can run Trigo wheels, this by cutting out the outer ball joint retainer and moving this inward. I know longer is better but I cant see that this will affect bumpsteer or angles to any great degree.
I contacted Lynn Park today and he has only 3.5" offset on the five lug design hubs, and my front track is to wide to utilize this offset. If I moved the whole lower arm pickup points inward that would upset the relationship of the lower arm to steering rack and cause bump steer, its easy to alter the top arm, and shorten the steering rack by cutting and re threading the arms if necessary, my track is just over 27" hub to hub. |
Ant,
For stability reasons, it's usually better with the longest control arms possible, but... If you decide to shorten your arms, make sure that the ball joints will not be forced beyond their designed maximum angles. |
Steering
strictlyperson!
Due to the steering rack used aussie Holden Torana, I have a track of 57.5" so by shortening the quite long steering arms, hopefully wont be a problem. I am going to contact Almac cars Wellington who made chassis body etc and get him to Tig a complete new arm up with this modification! |
