2g Front trailing arm(??) bushings

[nazthug]

how come no one makes these?

The bar that goes to the subframe from the spindle...you guys know which one im talking about, i can grab it with my hand and move it like 2" back and forth, seems like it would help forward/backward wheel hop

I am having a set of pooly bushings custom made here at the local suspension shop to replace the shity stock ones at the subframe, but is there a reason these arent being made and sold???

If they work well, i will have extras made, and sell them to people who need them maybe....just wanted to get input

There are two reasons why nobody makes these. First, the bracket is bonded to the bushing, so any replacement bushing would also need to have a replacement bracket. Second, you don't want to replace this bushing with anything harder. If you do, you'll lose the beneficial dynamic toe changes, cause a nasty loss in caster when steering, and generally cause the suspension to bind. I know of only one person who has even considered stiffening this bushing and I have a private wager that he'll undo the mod quite quickly.

ps. it's called a compression arm

I read the trailing arm part of the post...... It got my attention....

It is'nt a trailing arm... The rear has one of them. The chasis pivot point is forward of the suspension end attatchment.... The front is a leading arm.. It is called a longitudinal control arm by 'bishi.... The rear arm bushing is a good one to go poly with... I have seat time with a high HP car with ES bushings all in except the big honking rear trailing arm bushing in and after I installed it... On the rear it is a good thing to control dynamic toe a bit more with the bushing....

On the front I did'nt take into account the dynamic changes which are benificial into account and was only concerned about the dynamic bad changes... Like shock twist....

I was'nt considering running just a stiffer arm bushing but tying both lower arms together to form a single A-arm...

After looking things over completely... Up front Just run a pillow ball upper shock mount and spherical bushings at both points of the lateral control arm.

If you plan on running spherical bearings in the front arms of a 3300lb pig that's going to up close and personal with pot-holes and frost heaves, better plan on some serious subframe strengthening as well if you plan on making it past the end of the street.

The compression arm bolts are in single shear, which makes this arm even worse.

Replacing the rear trailing arm bushing is debatable - there are as many situations where the dynamic toe is a benefit as there are where it is a hinderance.

A rear trailing arm for a 2G is only about $30. So a back-to-back, same-course/same-day experiment is in order here. Consider it added to the list of things to do. Current estimates would place a posted update some time around August.

And I even have the bushings (Prothane) if you want to try it JT

Unfortunately you'll also need to swap the bushing in the upright, as that's where most of the toe change comes from. I no longer need any help in sweepers, so the toe change only benefits me now, that's lead to some reluctance on my part to play with the rear dynamic toe.

I have ES bushings... I think you should try them... Not as hard as prothane...

400-600+ hp those OE bushings were'nt designed for... Therefore one can speculate that maybe the stock ones flex just a little too much under launch....

DG has metal bushings in his lower front arms.... Not for a street car but I was expecting others here to have track only cars too..

Believe it or not I actually like the ES inner lower arm bushing... 3 piece design... The center puck is hard...in fact the hardest compound I have seen in the ES kit. The shock upper bushings were the softest. The outer sections of the arm bushing are made from a softer compound.. The center section of the bushing controls vertical movement while the outer sections allow the arm to swing a bit.
