Shelby & Boss suspension differences

[wenger828]

I'm gonna make this question simple.. what makes the Boss suspension and handling stand out and differ than the Shelby? I got an '11 and plan on road racing the car next year & really want to gear my modifications for better handling.

I personally like the griggs gr40ss system. Its their base system and dials in the rear suspension while tweaking the front. It gets all 4 corners riding on adjustable koni coilovers:beer: Its about twice the price of the frpp suspension but the results are amazing!

+1 on the SS. I have much of the SS package without the coilovers. I instead went with the FRPP suspension first and found it to be incomplete because it lacked UCA, LCAs, and an adjustable panhard bar. I opted for the Griggs torque arm, LCAs with brackets, and adjustable panhard bar (an example of Van at Revan Racing piecing together a system, as he routinely states is an option). When you add control arms, brackets, and panhard bar to the FRPP package, which is necessary, the difference in price isn't all that far off. The SS is definitely the way to go for someone who want an awesome street machine that handles track duty well.
