Just want to give major props to UMI, I’ve had my order in my garage since January and am just now getting around to doing the front suspension. Upon looking at the upper arms so had two driver side arms. Made a quick call and they got a passenger arm in the mail not more than an hour later. You guys rock! Can’t wait to follow this build especially since you are going to have some great videos of it.

But the important question is what size are they?

Four of the same size so we can rotate. Should be pretty nice for high performance summer driving.
Sounds familiar... 😉 same reasons I chose that size front and rear

I might have missed it, but what size rim and offset/backspace is being used with those tires? Can't wait to see the new stance!

I don't know if we published it yet but here's where we're headed:

Size - 18" x 9.5"
Bolt - 5 x 4.75
Offset - +1
Backspace - 5.29"
