Thread: STB differences

I purchased the GMPP suspension kit and I am wondering what the difference is, if any, between the STB that comes with it and the tubular ones that are available.

Thanks for your input.

the STB or strut tower bar, is the stock bar that came on most of the GTPs and Regals. The only tubular ones I know of are aftermarket. They attach to 2 or 3 of the upper strut bolts vs the factory mounting location, which also requires the factory mounting kit sold separately
I run the stock STB bar with aftermarket mounting plates

I would assume that the tubular options are a bit more rigid. I doubt the difference would be that noticeablethough. Thicker sway bars and control arms are going to improve handling much more noticeably than the STBs. I have BMR front and rear and the improvement was minimal, but they are beautiful STBs.

Thank you, that's what I was wondering.

i can't justify why an aftermarket bar would be better then the factory bar besides looks and additional cost

The aftermarkets well, some of them like BMR have the ability to put tension against the strut towers which is really what you want the other ones that have little surface area and just on the inner portions of the strut tower are not nearly as effective.

Yeah. They have the threaded ends.

Ive had both the factory mounts and these aluminum brackets.

It it was the rear bar that apparently proved these work. The rear bar was installed before there was aluminum adapter plates made. You would slightly elongate the holes on the stock front bar and it would fit
Fast forward a year or two , I get the plates made , removed the rear bar and I was shocked. The holes actually stretched a lot meaning there was some serious force going on back there.
Id spend the money getting a rear bar before getting one pretty one
