    Fully Polished Aluminum Strut Tower Brace for 98+Seville and 00+ Deville

    After I finish the mounts my next project is fabricating strut tower braces for the newer body Seville and Deville.

    It'll bolt directly in place across the strut towers and the main member will consist of 1" diameter solid aluminum bar- lightweight and very rigid. I've got the measurements and the prototype- I'll be sending off some blueprints to the fabrication shop and they're going to laser cut the ends for me. Each one will be fully polished: it'll make the engine bay stand out and keep the strut towers from flexing around corners.

    I don't have any photos yet. They're coming soon. First thing's first. Get those engine mounts done and shipped out.

    Dev boys will like this
    Sev boys already have a STB brace option
    GM makes one

    Now you know I'm going to be all over this.

    Have you actually looked at the 2000 + Devilles before saying you can make this? I think you might be in for a surprise.

    Incidentally, on the Deville series car, the flex isn't a problem. GM designed a bracing cross member into the firewall area just for that reason. The Devilles, stock are far more sturdy than the Seville series cars so this will be totally for show.

    If there IS any flexing going on I'm oblivious to it.

    Personally Ranger I don't think there is much flexing, if any at all. Some say they notice a difference with a brace bolted in place.

    Codewise you're right about that, I was just thinking about the fact that the Devilles switched to the newer platform almost identical to the Seville. There will be some differences. I have a 2000 Deville in need of HG's right now so when I pull it in the shop for that it's a good time to examine the options.

    What you're going to find is that it'll be impossible to make a straight point-to-point piece.

    The brake reservoir is in that line and protrudes higher than the strut towers. The only option is to go around it.

    Trust me, I had the Seville brace in my hand and looked at every option before selling it. I was very determined to make it work but it just wasn't happening.

    Now, I suppose you could 'box in the reservoir and come off that with straight tubing. Know what I mean? It would have to be strong with a little space because you don't want the brace to break the reservoir

    a strut brace sounds cool! how about some Anti sway bars? i mean i know its a big heavy car, but it sways a fiar amount in a turn onto a on ramp if i am doing it at a fair speed.
    P.S. what DIA of tubeing.. it will need some "NX8" logos to brand your product kinda like this

    Now there's something. The DTS has some pretty nice sway bars but they could be improved on.

    A thicker sturdier sway-bar with upgraded bushings would be even more welcomed.

    Didn't we decide that they wouldn't work on a DeVille ?

    Re: Fully Polished Aluminum Strut Tower Brace for 98+Seville and 00+ Deville

    I want some. I need my DTS to be a performance monster, even though I cant tune the engine and make more power, I can try to do some handling mods. I won't be able to take a Challenger SRT8 in straight line, but if I can make a win outta beating it in some turns, that would be sweet. Not that I plan on racing a SRT8 around some turns or nothing, but to theoretically be able to say I can would be nice. Never mind. I just want it.

    Re: Fully Polished Aluminum Strut Tower Brace for 98+Seville and 00+ Deville

    The first thing you want to do the create a handling monster is to lower it. You're going to loose ride quality but that's definitely the place to start.

    Another thing to do is lower profile tires. If you're running the stock 235-55-17 do a +1 size which I think works out to 235-50-18 ?

    I'm really regretting not going to 18" when I did my wheels but the tire cost is astronomically more.

    I don't feel much flex in the DTS either, and I push it to the limit around turns and such every once in a while. But in all fairness, there's nothing to compare flex (or lack of) too. The 01 base Dev is a whole 'nuther story...

    What is the ETA for the mounts?
