can you use relacation brackets with the stock arms...
can you use the boxed arms with stock brackets...
are boxed better than tubular...
whick bushing are better...poly chromoly??? advantages disadvantages...
its a street car
what do most of you guys use???

and wheres the best cheapest place to get these...
thanks
Daniel

 

Yes
Yes
Usually, but also depends on material
chromoly is a type of steel, not a bushing material

I went with the tubulars from BMR made from chromoly steel. Chromoly is stronger and lighter than conventional steel. (I was wanting a little less unsprung weight).

As far as the bushings, injuneer had a good write up on this maybe a month or 2 ago. There is a potential for binding when the suspension travels (bc of the panhard bar pusing the LCA's over a bit). I haven't had this problem. I am running poly/rubber bushings. They reccomend spherical ends though.

 

can someone link me to the write up...thanks

Well what I meant by write up was that he responded to someone that had a similiar question and he answered it well, so try a search, or just use what I suggested.

 

How much time do you spend turning vs. burning?

In general, bushings:
- Rubber is the quietest but offers the least control
- Poly offers less flex but prevents full-motion over time.
- Heim joints (aka rod-ends or spherical joints) offer the best performance, but you should get high quality QA1 with teflon liners to minimize noise and extend life. Expect to change them every couple of years. Regular inspection is recommended.

Some vendors offer a mixed LCA, with rubber/poly or poly/heim on the frame/axle ends. The usually offer the softer material on the frame side to minimize noise.

I think it would be more cost-effective to box in your stock control arms if you think they are flexing - unless you want heim joints in which case you'll need new arms.

Switching from Hotchkis boxed LCA's with poly bushings back to the stock arms with rubber bushings gave me better rear-end control while cornering.

Hope that helps...

 

That's because they will flex when cornering. Rod ends will fix that so you don't have to go back to the stockers.
