I kno a local tuner who has a 10sec LS/Vtec turbo drag car. And advised me not to buy the Z10 bars. Can anyone vouch for Z10 ? or recommend something like Jimfab ?

 

what kind of car is it going into?Do a search for jimfab or jim fab,this has been cover a million times,trust me its worth the search.

and an even better thread.Look for the post made by FFGeoff since he is the designer of the z10 bars,listen on how he talks about the jim fab design is way better.

I vouge for Z10 bars, I have tuned and dialed in many cars at the track where the bars have brought the 60' times down ...

I think my input is real and tangible rather than the open-ended responses such as: go search or go to "the best" company or don;t go to this company because "I designed the bars when I worked there and they are no good"

try talking to the people who have these bars and find out how they worked on their cars ... its that simple

z10 bars do this to bushings.

ur also biased cuz ur sponosred by them...

 

My unbiased opinion...

Do Z10 bars work (ie provide increased traction and reduced wheel-hop)?
Yes.

Are there other devices out there that are "better" (more traction, better geometry, more reliable, etc.)?
Yes.

One question though. To my untrained eye, it looks like the jimfab bars would suffer the same problem as the competition engineering bars <U>on the street</U>. That being decreased turning radius.

 

the jimfabs wouldnt suffer from the competition engineering problem, becuase of where it mounts on the lower control arm, its farther in there and at the crossmember than the CE.

 

I have the Comp. Eng. Bars on my car I suffer no decreased turning radius, my tires have never hit the bars, even with big slicks. Also I have an H22 motor and they clear the motor perfectly. Pretty decent bars in my opinion.

Hmmm, interesting. *flips through wallet*

 

so I take it the Jimfab traction bars are the best out there then. Are there any thing bad to them? ie weight? smaller turning radius-according to some there are none, etc?

and when woudl these bars be needed? like would a good lsd cover it, if one is making less then X amount of whp? and does it increase handling ability better with them on?

if one were to buy one first, would it be lsd, or these?

 

my take on the jimfabs, bad stuff listed first. The good FAR outweighs the bad, and dont get me started on the bad things for the other bars, i could go on for a long time.

BAD

1) the crossmember goes back awfully far. This seems pretty unnecessary, but on the flip side it means less moving mass and shorter radius arms. The bad part is that it could potentially be in the way of a dump tube, downpipe or IC piping

2) I wish jim had an option for an upgraded heim joint. While jimfab uses the same run of the mill heim as z10 (to save costs obviously, although z10 makes you pay for them, jim keeps the price right) these heims are poor quality, and will rattle around, making a lot of noise.

GOOD

1) The design is friggin awesome. No other traction bar that i have seen has geometry that is this close to being spot on. Jim understands suspension geometry and this design reflects that.

2) it includes a nice CNC machined billet aluminum mount. This gives the radius arm a strong, appropriately placed mount, which will not tear the bushings to hell everytime you stomp on the gas. This billet mount alone is worth 50$. And there are 2.

3) The powdercoat is a high quality and gorgeous coat

4) The price is super affordable.


The reason so many companies have gotten away in the past with the facade/illusion that their bars work well is simply becuase the binding of the suspension actually *increases* spring rate thru the bending of the car. The front end and frame rails are getting bent back and forth from the radius arms that use improper geometry. High spring rates, low wheel travel and combine that with poeple who do not understand suspension geometry doing design work can cause probs.

Ive got jimfab bars on my car and i could make anything i wanted to at my fabshop.

 

how bad is the rattling noise you mention about?

I take it these bars don't do anything for handling around corners? or does it?

So lsd or these first?

Thanks for the previous detailed response

 

I have some more pics of the great bushing work thanks to z10.

sorry i wish i knew better back then

 

I Like my Jim fab's on our coupe, we are starting to get the car dialed in and have hit 1.68 sixty foots, in a 2630 pound car....enough said.

 

I have some more pics of the great bushing work thanks to z10- I change out my bushing monthly.

 

a hot girl told me not to get z 10 she said they were designed wrong!

That would be Chrissy, who does no longer work for Z10 anymore.

 

Ive been using the Z10's for awhile now. Completely eliminated wheel hop, so they did their job. The car also felt much more stable on the highway and it seemed like it improved handling and braking as well. I have never inspected my bushings, I prolly will soon, but I always heard the suspension binding up on hard braking.

 

I don't get it. If they know the design is faulty, why not change it ? And about the noise from the heims, how long before it manifest itself ? Also, anything preventing us from upgrading them ?

 

yes that was Chrissy lol .
if im not mistaken Jeoff and Chrissy both worked for Z10, and pushed thier products pretty well until not working there anymore ? thats just what i hear
as far as the Z10's i have thme , they did cut down on wheel hop to an extent, but tires also play a part in wheel hop . on slicks i can tell you i get no hop at all .

 

The Z10's work well enough for me, but there is no doubt that they increase suspension noise . You also feel every bump in the road with them, and the turning radius is only slightly affected.
So far my lower control arm bushings are o.k., but eventually I will probably sell the Z10's and get the JimFabs.

 

Krissy is a cool kat, and yeah, it seems like Z10 is cool, until you dont work there no more, hehe, But i cant say anything about them becuse i have never used their products, and at this point, i may never, so not too sure.. Geoff says that the mounting point of the arms puts the car an driver in harms way. I wouldnt second guess his expert judement, so id reconsider if you were thinkin about purchasing them. just my $0.02
