I noticed that these little brackets ACTUALLY ARE the best mod as far as a traction upgrade. I have all the other stuff done: SFC, LCAs, Premium Struts/shocks and Springs, Panhard Bar and TQ Arm.
The biggest difference I recently felt is after I welded on these brackets my car really hooks up! Some times to a point where I think my Centerforse clutch is slipping.

My question is: Does this put more stress on the rear end? Mine is stock w/100K+(sans the 4.10 gear change) and my engine and tranny are upgraded.

 

Shock loading...If you're hooking harder, it's harder on your rear end. If you're running slicks and hooking hard with a 10 bolt, you're pushing it to the limits.

edit:
If this is the best 60' you're getting, you should be fine.

 

That 60 foot time was before my suspention mods. I'm hoping to reduce it.

 

I'm cutting a 1.84 on radial tires and no SFC's, LCA's, brackets on a t top car. After these mods I hope to hit low 1.7's then buh-bye stock 7.5 bolt. Damn cheap rear ends.

 

yeah with all my suspension done i am definitely putting power to the ground but the tires still cant hold first gear at the track, i know i have alot better 60 foots in the car.

 

As long as you're running radial street tires you should be ok.

The factory 7.5 10 bolt rear is really hit or miss. The process control on the materials and machining is so loose that sometimes one comes in right on the edge of unacceptable, while others are made really well and never break.

 

I hope mine is the latter of the two
