Default Best suspension setup only necessities

Ok guys I have a 2010 2DR wrangler that I put 18/60 coils and rubicon shocks on from a 4dr that gave me about 1.75" of lift and I'm running 35s with flat fenders. I'm looking to get a little bit more hight I'm thinking 2.5" would be perfect to get more flex and minimize the rubbing. So what I'm looking to do is create a 2.5" lift with only the stuff I really need so I'm not wasting money on a lift when I'm keeping the jeep so low. My idea was to get a set of 2.5" coils either rock krawler or metalcloack (I would like opinions on both) and get synergy front and rear track bars. As well as a set of fox shocks. I might also need extended break lines and front lower adjustable control arms I'm not sure. So I have a bunch of questions. What am I forgetting? Which coils should I choose? What length fox shocks? I would like to try not to extend my bump stops to maximize my travel but I don't want to bottom out the longer shocks at full bump

Any information would be great thanks in advance

.75" coil spacers instead? For longer shocks, you should probably plan on extended bumpstops regardless.

Read a few threads on the various coils and compare to your specific vehicle weight. You might get 2.5", or you could be at 4". Which specific components you might want to add will depend on the actual height you end up at, and your personal opinion on the handling. If you want new coils, why not just start with whatever you find in the basic lift kits from either mfg and go from there?

Thanks for putting us in the mix!! 2.5" lift with 35" tires fits both with and without flat fenders. However, if you're going flat fender we typically recommend the x-factory lift systems. These systems re-center your rear axle in the wheel well opening allowing for a better fit and better look. At a minimum, we recommend a flex system so you can adjust your caster. As for coil springs we really feel like our new triple rate springs are a winner. We have the correct length so they'll never unload and drop out. The rate that the vehicle rides on is soft and comfortable for daily driving and is ultimately supported by our final rate that helps prevent hard bottoming and adds stability when crawling.

Let us know if you have any other questions or concerns.

So how much lift should I expect from your 2.5" coils on a 2dr jk? I have a poisonspyder BFH front bumper with brawler bar. Poisonspyder BFH rear bumper and steel Genright swing away tire carrier. I have also removed the rear seats and built boxes in the back of my jeep out of 3/4" plywood and my spare is a 35" nitto trail grappler on a 17" alloy wheel

On a 2.5" lift you should see 2.5" with all the luggage. We create our springs to support full width bumpers, winches, oversized spare tires, and heavy accessories. Without the heavy accessories you will see up to a half inch of additional lift.

Here is one that a local customer finished last night. 2.5" X-Factor with 37" Toyo Tires:



And here is a good flat fender reference:
