Vogtlands vs Eibach



The 25mm bar is hollow, the 639 bar is solid. IMO the 2179 bar matches the 34mm GMPP hollow front bar much better. These cars weigh enough, that Dorman bar for the front is solid and 33mm, and weighs a ton. Plus it comes with cheap rubber bushings most don't use. Moog replacement bushings for the front are poly. I have the front set up, havn't installed as not sure which direction I am going yet. It requires the older style front control arms to be replaced on my car. I picked up the GMPP front bar brand new on eBay for 55 shipped, I think that is a good value. I'm not concerned with it rusting out.
 
My Dorman front is 34mm IIRC, but I doubt there's much a of a difference from 33-34mm, but I'd bet it being solid makes a different.
 
The solid bar is probably better, I installed one on a family members 2001 Impala. Its heavy, but that was not a concern on that car as were the cheap bushings. I grabbed that Dorman bar at Pepboys, with a 30 percent off coupon it was 70 dollars plus tax. I wouldn't use it on my GXP, the car weighs enough. every bit helps.

Awh man why'd you show me that? Now I got a new sway bar obsession, not the 639 anymore I want the 2179 now Lol, with 25 mm hollow I'd just fluid film it and hope it wont rust as bad... I'm down to pay the extra $50 for the 25 mm over the 22, 34/25 should be an awesome balance and the car should be ridiculously flat
 
And I just ordered the 2179 off of jeggs.... it says it'll ship by 10/16 but for some reason I doubt it $252 for it
 


I feel like with neverenoughauto I'd be calling them every other day to see if it's shipped or not.... plus it looked a little cheap, $193 compared to $250 in other places so i was kinda afraid the product might be wrong (639 is priced at $193
 
That's over 50 bucks, worth the call. You can always cancel Jeggs order. I posted that link as it was the cheapest I could find and I did a lot of suspension research. Spend that extra money elsewhere if its still available.

Yeah I just have more to trust in Jeggs and I'm down to spend the extra $50 if I get the right parts and well get it at all. I think the handling's gonna be taken to a whole new level with the 34mm front/25 rears, only issue is rust and I'll see what I can do to prevent it as much as I can, fluid film it maybe?
 
There's a bunch of guys that ordered from neverenough..there's a reason you use PayPal or credit card chargeback as a worse case scenario. That's $50 you could of saved. Plus if your thinking jegs or summits gonna ship it within a week I would change your expectation unless they have it on hand it's gonna come from Addco.


Oh and there's markup a company goal is to make profit not just break even by selling things at cost

To each his own I guess, I still say it's worth a few more pounds to have solid bars, especially in the rear. I'd be willing to bet the 22mm solid Addco out performs the 25mm hollow Addco. I don't know on the 25mm, but the 22mm has quite a few less bends to it compared to GMPP and stock, so that'd make it stiffer for sure. Post pics of the 25mm when you get it if you don't mind.

I'll def post pics when I get the bar but it'll me a while I'm sure
 
I'm no engineer, so I don't know if solid is better than hollow or if it just adds an extra 20 lbs to the nose of the car. Where's the engineers...?
 
I asked a few engineers at work (I'm not arguing about anything, I'm genuinely wondering), and they all said solid would be better without a doubt. How much better? We'd have to know the wall thickness, what the metal is made out of, etc. I dunno about a 20 pound difference, there might be a combined difference of 20 pounds with the front and rear being solid.

Whats 20 lbs to an already 3500 lbs car? I've read the Doorman front is actually stiffer than the GMPP, wouldn't you want the softer GMPP for the front to tighten it up just a little and still have ample grip? Or is the GP's body lean so much that stiffer front is better? Dezebe's 38 mm front bar leads me to believe the latter is true
 
Yup weight shouldn't be a worry when your talking 20lbs on a already heavy car

Oh.. I agree and like to read that engineers suggest X is better.

I also know that for some odd reason..that car defied a lot of expectations ... :th_king-evil: It's why Scotty got F bodies.
