The 2000 + Bonne'* don't come with STB. A big change from the 99 models was the designers moving the firewall in line with the strut towers, so no brace is now required or would, l think, be beneficial.

OK, so STB'* were factory from '92-'99 so why are you going to make them?? There will not be much demand for the 2000+ for the simple reason of they handle really good already, and it would be difficult to make some.

First these look a whole let better than our stock ones do, plus I'm getting rear STB'* made which NO Bonneville comes with out of GM! So if you've got a front STB, well you could still use a Rear STB right? For those who don't even have a Front STB, well, this way you can get one. as for the difficulty part, no mod is ever simple.

I would like to thank all who responded, but I need all these STB measurements & so far only Will & FiReDeViL have been kind enough to provide them. I still need the older (86-91) Bonneville measurements & the 2000+ Bonneville Measurements too.

Al, I can tell you the distance between the stud closest to the front passenger to the hole closest to the driver is 1036 CM. 518cm to the centerline of the engine bay.

On the 2000 and up, These same holes are 558cm to the centerline, but the 87-91 is identical to the 92-99. Some conflicting data on this.....the 1036 is listed as 1038 in another book.

I don't know the hole pattern size, though. I could make a template and figure it out if you need me to. I can also measure and verify the 1036 or 1038.

So does the 86-99 Bonnevilles all use the same Front STB then Will according to your book? How far apart EXACTLY are the two bolts that hold down the STB to the strut tower on the 86-91'*, 92-99'* & 2000+'*? Are they all the same? :? How about the distance from Passenger'* rear bolt to Driver'* rear bolt? How about design features? Any raised or dropped portions of the bar?

did you ditch your car?? Your 92 should have the same one mine does, all the way up to 99. I don't have a metric tape measure here, but do at work. All my specs are listed in MM. The 92-99 strut bar will fit the 87-91 like a glove.

The bottom edge of the bar is even with the top of the strut tower, but the top of the bar can't go much higher. In hard cornering, my bar flexes and rubs on the hood insulation.

So that just leaves the 2000+ owners then!
BTW, my STB rubs the hood too! Have to modify it for my new hood liner which is Mirrored Stainless!

You weren't listening Deathrat. I think that the 2000+ Bonne'* will not benefit from them. The firewall is in direct line with the centerline of the strut towers. I don't even think a brace would fit if you wanted it to.....and even if you could, they couldn't be stiffer than the firewall.

I was listening btw, it'* just I think otherwise as these were for sale by myself in particular until a production accident happened & my supplier has been unable to get a 2000+ Bonneville to take apart to re-measure it. An angled STB will work better than the stock suspension I think because you'll still illiminate the Strut Tower flex that occurs in all fwd vehicles.
