Larry, What ever happened with the no-hop bars? My car has a serious hop problem and I need to do something. I've kind of been waiting to see how your deal worked out because I don't want any aggravation when I go to install them on my car. I have a 12 bolt posi from a 69 Chevy so I'm not sure how much different my center section if from yours.
Andy, I couldn't get them to fit, no way, no how. I contacted Edelbrock, and they basically denied it was a design problem. They said that there was something wrong with my rear webbing. They did however give me permission to return them to the point of purchase (Sumitt), which I did, getting a full refund. The left fit with no problem, the right, no way, and we really ground on it. I'm probably better off without them, I managed a 1.84 60' with just the MT ET street Drag radials and air bags. That's good enough for me.
Andy, replace all of your bushings and make sure the shocks are in good shape. The wheel-hop should go away with just that.
Adam, Thanks for the advice but there's a couple of things about my car you don't know. The all the bushings are new and so are the shocks. The bushings are polygraphite. Do you think that may be part of the problem? I also raised the rear ride height with spacers on top of the springs which obviously changes the angle of the upper arms in the opposite direction than the no-hop bars do. I measured 27 inches from the ground through the center of the rear axle up to the rear wheel arch molding. The assembly manual says 23.02 for shylarks and 24.32 for the GS so it's up there 3 or 4 inches from stock.
Well, put the TA Performance No-Hop Bars on today. What a difference in fit. They went right on, not like the Edelbrocks (which I returned)
While I was at it, I installed the HR PartsnStuff Rear anti sway bar. Didn't get much of a chance to test. Soon
Larry, you dog you. :laugh: That's the rear sway bar I want as well (trick). How hard was the install? Also, why the no-hops with the rear sway bar? Thought the HR Parts bar worked great on it's own, with maybe the only addition being an air bag.
The No-Hops change the instant center, so the tires hit harder. The HR bar has handling and traction benefits, and supposedly you don't need airbags with it. I had the No Hop bars all ready to go in when I got a good deal on a used HR Parts bar from a friend of mine. Seemed like the thing to do, install them both. :laugh: The HR bar is an easy install. Just some measuring and drilling 4 holes in the rear crossmember.
Larry, Now that you are crossing the street car/track car line it may pay to have Rob C. check the rear internals. Play it safe because you just increased the "hammer" by about 1/3. :Smarty: But you already knew that Mr. Wizzer!
What kind of difference do the No-Hop bars make on the street? It looks like they'd increase the NVH (noise, vibration, harshness) of the car? IT looks to me like they limit the travel of the rear axle, or am I seeing them wrong?
Already did. When the heads were put on, I had Rob pull the rear cover, have a look around, and refill with Amsoil synthetic :TU: Everything was looking good. If the 8.2 goes, it goes. I'll replace it with an 8.5. I might do that anyway.
They change the instant center. I haven't noticed any change in ride at all. The handling has improved quite a bit from the rear bar. So far so good. The no-Hop bars will make the chassis try to push the rear end downward planting the tires better.
Thanks Larry, Not 100% sure what direction Im going to be going with my suspension so I figured I'd ask.
When it does go (just a matter of time) I have a nice 12 bolt with 411's ready to put the rubber to the pavement. :Brow:
4.11 are drag racing gears, gota stick with my 3.42's or even 3.55's Don't the 12 bolts use c clips? Think I'd rather have a good 8.5
Larry, I'm going to do these this week along with the lower arms I got from Dominic @ Marcus, how did you set up your pinion angle?
Never checked the pinion angle Paul. Next time I drop the driveshaft, I will. Don't think it is that critical for my power level. The No-Hop bars shouldn't change the angle enough to matter.
