Hey guys, I'm in need of some small info. I asked this before in another thread, but I think I tried to get to many answers at once and never got any response.
My problem is, after I installed coils, the bolts are not long enough anymore and I can't install the strut bar. I bught some nuts in home depo, they have a strannge bottom, though, they were called tensi nut.
Anyway, can I change the stock nuts to these ? And do I need the black stock spacer between the strut and the body ?
Here's few pics.

The bottom of those new botls I bought..

Well, you definitely don't need the spacer with the strut bar. As far as the nut...
I dunno. Provided they're high strength, they would probably work...
I would just use the existing ones, although it looks like they might be a bit rounded off.

 

the sotck one won't catch any thread on the bolt, the threads on the stock start halfway through the nut, u can make it out in the photo.

 

Are the new ones high quality (grade 8+?)
If they are, give them a shot, but keep an eye on it.

 

Or maybe use the stock nuts - upside down - with a washer?

 

29 ft-lbs of torque is all it needs...

 

Ditch the black spacer, and you should be fine with the new nuts. Actually some coilovers come with that type of nut, so you're good to go.
