how is everyone?
I was trying to install the Cusco 3 points X brace, but the problem was that I could not unbolt those 2 bolts on each side, I am not sure what size i have to use for them, i guess they are 17mm(correct me if I was wrong please)....
Also, how tight are those bolts from factory setting?

thank you very much!

 

my bad looks like 14mm, not sure on lbs from stock, but guess is around 150- 200lbs..... get a longer wrench

 

They spec out at 28ftlbs. I know that the bolts are M10 X 1.25 but I don't remember the size of the bolt heads. I think it is 14mm

 

i have tried the 17mm, it seems fit the bolts, but i still can not open them.... is there any trick to open them?
please help me out on this.
thank you very much!

 

are you talking about the subframe bolts? I remember those are 17mms.
use a really long drive rachet. It really helps.
some WD40 also helps.

 

14 is the front one (single) and the other four are 17mm. They shouldn't be that tough to get off so they must be rusted. Spray them with some penetrating lube (wd40 or equivalent) and wait a few minutes then reapply and try to break them loose with a mallet.
