RF hold down shock

[turnecm]

What is a good rebound valving range for an adjustable rf shock using stacker springs or bump stops?

1,000-1,800 lbs @ 1"per second would be a good starting point.

How would a car tend to react if you had too much tie down on the right front? Would the RF tire be noticably hotter? Would the car have a push coming off the corner? Thanks.

Isn't that supposed to be at 6"/sec?

Anyone have any input? Thanks

what valving would that be equal to? an 8-12?

I'd say usually a lack of sustained forward bite, which leads to wheel spin and loose exit..

the trend seems to be leading to a rebound around a 10-14 around here depending on whos theory's you believe and track surface. i wouldn buy a new shock if it didn go to at least 12. in afco "valving" . just what ive seen around here

Lazers are baselined for a 5-12 at least depending on track and thats with their preferred shock brand. You can't cross compare shocks for 8-12 and so on. You would have to compare dyno sheets when you found what you wanted. If your chassis manufacturer calls for a certain valving ask them what brand they call for. Companies rate their shocks at different shock shaft velocities to come up with thir own ratios as compared to the next company. If you can find out what company they use and their numbers you can then compare it to say your afcos an 8-12 for them might be a 7-10 in another

I believe that the rf shock is one of the most debated topics in latemodel racing today, there is people from 300lb at 6" per sec to 1200lb at 6" per sec! On bump stops you gotta be carefull of too much high speed rebound, i feel that if guys are running those 1000lb numbers it had better be smooth or your driver will hate you! I'm more of a digressive kind of guy u tend not get urself in as much trouble with those big high speed numbers! I found myself adjusting rf comp more this year than anything it seemed to help with my attitude/ control if there were any high shaft speeds

1,000-1,800 lbs @ 1"per second would be a good starting point.

There are some rocket guys running these numbers. We have had some pretty good success with 900 to 1000 @1" per sec.

Don't get too complicated a simple 4/10 split.

i agree with brandon...you don't want to over think things....keep it simple....an adjustable shock.. with a decent range to fine tune but for the most part a 4 10 or similar should work well.....all depends on how driver feels ....and how car reacts to his style.....every driver is diff and so is every car.....
