lower axle mounts were not re drilled because it doesn't let me have the anti squat it needs to keep the front end on the ground, this was a hard one to realize since I've tried to keep the lower arms as flat as possible on alot of rigs over the years. one of the rigs that really bugged me was a midarm I did last year with 22.5" control arms, 4.5" mc springs and 14" travel bilstiens. after messing with it I figured out why.
re drilling the lowers is awesome with stock length short arms when using the upper geometry correction brackets and basically follows the same plane as the mid arm geometry using the stock lower axle end bolt hole.
The uppers are raised the same as always, what i did was drilled the track bar mount slightly lower to keep it off the body because it doesn't have a body lift.
I will likely never use another dual durometer bushing, ever. literally every single synergy control arm i've sold and every mid arm I have built in the last 5 years using dual durometer bushings, have been replaced within 18 months. one set was only driven 30 miles before it was sloppy and had symtoms of a loose bolt. synergy has decided I have to pay 50% for replacements that have little to no mileage on them and I have to send them in for inspection. the labor involved in changing them is not free. I am back to using Factory JK control arm bushings and as much as I hate the squaking, you'll likely see some MC bushings in the future.
Psrivats' control arms have factory JLU bushings and currie joints.
I kind of wondered about that the more I ponder going to longer arms from what I have now (Nth Degree geometry correction kit) and if the AS would be too low. Also interesting on the DDB. I have been running them for a couple years so far successfully on short arms. I guess I will just have to keep an eye on them.
