5100 vs 5150 shocks

I was talking to a buddy of mine and he was wondering if he should go with 5150 bilstiens over the 5100s. I dont know anything about the 5150 since just about everyone on here suggest the 5100s.

My question is this, what are the difference between the two shocks? and why would I want to get the 5150s over the 5100s?

If there is already a thread answering these questionS, I apologize. I just did a quick search but didn't see anything that answer my questions.

 

IIRC the 5150's have more travel

 

For the front all you need is the 5100s. In the rear you can choose the 5150s if you want a tad bit more flex due to the longer travel

5150s are not adjustable. they are set lengths
