what about the rrm piggyback? i've been reading up on it. i'm considering buying one this summer. most people say it's the one mod that gives you the most bang for the buck

 

Cool, I'll check them out.

 

I had the piggyback for a while. I didn't think it was worth $450 worth of performance. It felt like it pulled better on the highway. So I sold it.

 

And the lowering springs can be installed easily right?

 

Closed, as these topics have been covered to death. To answer your last question, unless you have the proper tools and know-how, you're best off having lowering springs installed for you.

 

With an impact gun and a how to on here, its very easy. Go for it yourself if you know what to unbolt
