I just got a 12 bolt diff, and it came with no-hop bars...http://store.summitracing.com/egnsearch.asp?N=700+400272+115+308534&autoview=sku.

What would I sacrifice in ride or handling by using these on a street driven car ? I plan to race it as much as I can, but do want to drive on street on occaision.

Any personal experiences or ideas would be appreciated. :)

Thank you, John

If they're anything like the SSM or Jegsters I'd say no. I just put Jegsters on mine and I don't notice any difference in ride or handling but when you launch it you can feel it lift.

watch your pinion angle!!!!!!

mine was WAY!!!! off after the installation of those, had to use some adjustable upper control arms to correct it

I've had 'em on my 'Camino for years. The pickups are a special case, they don't have as much clearance over the rear axle and so I put a couple of dents into the bed, and therefore had to install some coil spring spacers to lift the rear to stock ride height.

You'll have no problem with a car. Be aware that panic braking may skid the rear wheels. The bars increase the load on the rear wheels when accelerating--they do the opposite under braking. In normal use this is a non-issue.

If you're installing them on a virgin axle--you just take care when drilling the holes in the axle webs so your pinion angle is correct to begin with. Since they're already installed--yeah, you'll want to verify that your pinion angle is correct.

I have them and I'm happy with them. adjusting the pinion angle to install them raised an eyebrow,but so far no problems

I have had them on my car since I got it (12 years) and have never noticed any ill effects from them..

They were installed on this axle, and run on a 70 ??? Chevelle.
Thanks for the feedback.

Vince, you forgot to add how you did that all in 15 min. with your bare hands....just like I did on mine.

Good times.

Not.

John, If you dont have your car raised up in the back, I would say just run the stock setup. I would only run those if I got wheel hop IMHO.

Nah, maybe more like 20 min ;). Here's some of the massaging that was needed on one of them. But hey, they work great!

Thanks guys, a pic really is worth a thousand words. I'll look forward to getting these when i drop the BB in

I'd only use them if your car is lifted from stock height in the rear...
