Hey i was looking at Mopar Springs at my dodge dealer and they have coilovers for 1 inch drop. There are two different ones tho.....and i dunno which ones to get?

1. High rate- front-150 rear-150

2. Extra High rate- front-180 rear-230

Which ones are better?

 

Those numbers don't look right...

Stock are 150/120 (front/rear) for ACR's, R/T's. 140/120 for most of the rest.
High Rates are 225/185
X-Highs are 310/230

Both versions of the Mopar springs lower the same amount, ~1.5".

Better? Stiffer springs mean less body roll... They also mean a harsher ride. And neither is a good idea for stock struts (unless you have stock Koni's, which you don't). And if the dealer is charging more than $60 for a pair, look elsewhere.

For the money you'd spend on Koni's and Mopars, consider the complete coilover set at phantomhp.com - $950 for height adjustable, compression/rebound adjustable (single **** like Koni's), and camber adjustable (camber plates for the front) is a very hard deal to beat. Spring rates are a little higher than the X-Highs. Once my house is built and I can work on my car again, I plan on going this route.

Best of luck!
