Rear STB Differences

**jmoore4294** · 07-15-2011

So why cant 04+ use a rear STB from a 97-03? Is it because the bolt pattern is different? Or is there some other factor?

The strut towers themselves are probably different. Different width etc etc.

You mean the width between the two strut towers or the shape of the strut towers themselves not the same?

That's what I think he means. I'm not sure if there's an adjustable or 04+ specific model.
Maybe Drunkie knows?

IIRC, the towers are diff shapes.

Well ZZP sells theirs for the 04+ that's "adjustable". Then there's BMR's "adjustable" ones, but for the rear they state it only fits 97-03. I'd rather buy an STB that has brackets that use all 3 bolts. And for the rear it seems that you can only buy one like that for 97-03 so I was wondering what made them different and why all these vendors say they won't fit.

I'm using Don Rome brackets on a factory stb for the rear in my 04. They went on just fine for me

I don't think there is any difference, I'm using coilovers that guys install in the 97-03s and I just looked at advanceautoparts.com to see if the strut top mount in the rear was different, but the 97-03's and 04+ all use the same part number for a strut top mount. So we know that the bolt pattern in the rear is the same, I'm wondering if they adjusted the frame a little so the strut towers are a little further apart, but that would mess too much with the suspension geometry. I do know that a few guys had problems with the ZZP STB fitting because they weren't long enough on their 97-03s, so I'm gonna say that the 04's for the rears are adjustable

We do have the DR brackets with the OEM STB option as well.

So logically speaking, if I were to maybe pick up a rear STB with a heim joint (i.e adjustable one), it would probably fit? I'm actually running DR brackets and the GMPP bar in the rear, but as far as I know, the strut tower can still flex. And when student loan refunds get here, I'm doing an overhaul on the rear suspension and figured I'd get a set of STB's with 3 hole mounting brackets for an overall stronger design.
