Mr. Kelly, after speaking with you in PM's and reading this thread, how much would one benefit from having the BMR uca mount with the adjustability? Everything else is BMR(adj poly upper, poly lowers, brackets and panhard), so if I would benefit from it, I'll install when when I pull the rear to weld the tubes. Car is lowered on P-springs (~1.25").
Will it help plant the rear to help the 60'?
It will not benefit you much, in terms of promoting more traction.
On a lowered car, the lower mounting point on our UCA is typically not recommended (by me) - as I prefer the AS/IC to be adjusted with the LCA.
On a stock ride-height car, the lower hole in our mount does wonders.
When someone chooses these components, on a lowered car - I still recommend them purchasing and installing the UCM002 Upper Mount, simply because it will reduce the movement within the UCA system. The stock Upper Mount's hole for the UCA bolt is substantially larger than the bolt itself.
Notice the slop in the picture below on the stock Mount, compared to the BMR Mount. Also notice, the marks on the inside of the mount, on the stock piece, where the factory style sleeves "dig" into the mount, to prevent clunking. The aftermarket parts do not have the same style sleeves, so they do not "dig" into the stock mount, and prevent movement/clunk.
