UMI Boxed Front Lower Control Arms and Shock Hardware Size?
Who else has the newer UMI boxed control arms installed?
These ones: http://umiperformance.com/catalog/in...roducts_id=620
Did a lot of searching and couldn't find any pictures. The lower shock mounting tabs sit on top of the pegs, does anyone have a picture and can anyone tell me what size hardware they used to mount them?
The stock GM Metric bolts were far too short when I mocked everything up. I really didn't think the mounting tab on the Koni's was any thicker than Decarbons. I've been running the Koni's on stock front lower control arms for a couple of years with no issue.

I've got 'em. Not the best picture as my car is sitting on the ground and not on my ramps. It's been awhile since I installed mine so I don't remember exact bolt size. Whatever the stock bolt diameter is, but 4" long. I bought new washers and nuts, also. Grade 8. The reason you need longer bolts is because the pegs on the LCAs is thicker then the stock LCAs. These LCAs are also going to raise your ride height by a 1/4 to a 1/2 inch...despite what UMI says. My airdam used to scrape on my driveway approach pretty good, but after the install, not so much.
I've heard that about these arms although I did see Ramey say it isn't true. It did seem a bit higher when I mocked everything up. I'll be screwed if that happens because the car is on Koni/LG Springs, no ride height adjustability. Makes me appreciate the KW V3 setup I have on my DD.

I personally say no. I run them on my Trans Am, it is street driven and some autox track time. The Roto-Joints have proven to be very quiet and a great option over rod ends.
Hope that helps,

I haven't been able to drive the car yet but I seriously doubt it.
I have Spohn's equivalent on my rear lower control arms and drove on them for a season and they were quiet as quiet can be. Much better option than rod ends for a street car in my opinion.
