Coil over rack and pinion

[grasshopper]

I am installing a 5.7 Hemi in my 71 Challenger and was thinking of changing the front and rear suspension systems. I have identified a few that seem to have potential ( RMS, Magnum Force, and XV motorsports) and was wondering if anyone could provide any feedback. Are there any other I should consider?
Thanks,
grasshopper

I think you'll find the one with the highest customer service satisfaction to be RMS.

Are you looking for a stock setup (2007-2012 Dodge) or aftermarket?

prefer a good aftermarket. How does that compare to a new stock one?
