And on the same lets use a cobra IRS set up for example. Is the added weight (just assuming, IDK the exact weights of both) of packaging this system really worth it? What's you guys take?

As I said sorry for such a general and vague question but I'm just thinking out loud and looking for opinions.

Thanks

Kody, first I think you are off a bit on that $10K?? I think the A/M unit is almost $12K just for the unit and then if you can't install it yourself you have another $6-8K in labor to install it. Now again you will close to that to install most of the 3-4 link setups as well so more of a wash on the labor end.

As for the Roadster Shop setup your not just buying their IRS your buying a complete chassis but if you start adding up all the cost of ALL of your suspension its not that far off with the added cost of labor compared to installing the RS frame.

Now as far as the rest I have know idea but as most would say, what are your goals? Have fun look cool, or are you looking to be at the front of the pack?

I know your just kicking around the question but to think about for sure, but great topic for sure, especially with all the opinions we have today from a lot of great company's making awesome products!!
