To be clear, there really is no comparison between an EVO DTD complete with bypass shocks and a bolt-on coil over kit. I mean, that's like comparing apples and oranges but of course, the price difference between the two is significant too. A closer comparison would be the DTD setup with just single coil overs but even at that, you would still have about 2" more travel up front and almost 3" in the rear. If you can afford it, there is no question that the DTD is the way to go and in my opinion, there is NOTHING out there made by ANY other manufacture that can even come close to its performance on the rocks or bombing through the desert. NO other kit has a cantilever system that gets your coil overs up and out of harms way, no other kit allows you to set your ride height as low as the DTD and NO other kit will give you the 14" of vertical travel (full bump to full droop) that it provides as well.
Having said all that, I personally feel that the EVO bolt-on coil over kit works exceptionally well and in my opinion, there's nothing out there that performs as well as it (standard coil kit or even any other coil over setup) outside of the DTD. After 2 years and almost 60,000 miles of hard play, I can tell you that they still work great and have only damaged one rear coil over during that time. I have swapped in heavier springs in the rear since to help accommodate the extra weight I normally have on board but of course, that's one of the perks of running coil overs - they are adjustable and can be fine tuned to how you want them to be. I have had them rebuilt once as well but, that was more out of routine maintenance and not because I had any problems with them.
I don't know if I've answered your question or not but, if there's something specific you are wanting to know about, please let me know. :yup:
