Lift Sticks/5th & 6th coil combos

[fastford]

if you could preload the bushings both ways , then it would probably cut down on total travel of the lift arm in relation to mounting point on chassis , so you would probably need a pretty stiff shock mounted closer to the rear end to have a good effect , were just getting around to trying the digressive set up with springs , i do think this stick might be something to try as well , because i have always been one to try things out side the box , how do you contact this curtis guy?

I just went to the web site and then went to “contact us” and started talking with him that way. Haven’t heard from him in a little bit. I know he did have surgery recently and was away for a bit. Another thing I’ve been trying to work on is to get away from springs and rubber entirely. A hydraulic cylinder with check valves, control valves and pressure relief valves to control the speed and pressure of the fluid. Set up properly you could make it progressive, linear, digressive, or even have it progressive and then turn digressive. Have it fully adjustable from under the car. I know a lot of guys who do hydraulic work and instrumentation controls on gas wells so they have a lot of know how. Still in the drawing up stages but hopefully I can make it real eventually here.

^^^Sounds illegal. LOL

I have saw a shock , basically a hydraulic cylinder with no spring or rubber of any kind on it , a few years back , he was very good when track was smooth and slick , but any rough or tacky , and he was terrible , I can see where what you are talking about , if designed to be adjustable for any condition , would be great , BUT , as MSR stated above , with every one focusing on cost reduction as being the answer to all the DLM problems now days , it will be banned by the time it hits the track ,

Possibly illegal to show up to a race with. Not illegal to test with lol.

The Lift stick i seen on a LM had the stick and a shock in front, not sure of the valving of course but a good DA there you could have the whole realm of sustainability.

Just put a reese bar on and be done with it....

Anybody got any pictures or web site ?

Just google JDM lift stick. $400!?! No thanks.

People acting like bumpstops or something other then a spring on the 5th coil is something new, We won MLRA championships and tons of races on it 10 years ago. Now I'm not saying that was the sole reason or that is was even much of a factor but something we was doing clear back then.

I know people where doing it way before me, least back to around 2005 or so.

I guess I should add this: Just like anything it's another tool in the tool box, not that it's right or wrong to do it but just different. You can maybe help some situations and just as likely hurt yourself in others and there is no super magic there it's more of a tuning/timing deal then anything.

Sure separating/combining the 5th and 6th coil may have some advantages but also has some disadvantages, racing is a series of compromises. You pick the situation/adjustment that gives the most of what you want with the least compromise or bad side effects.

I'm still a believer that there isn't any real serious gain in the whole 5th spring set up, but you can tune with it for sure but don't expect to find much of a gain with a good handling car. Now if your fighting always tight/loose across the center or something, then sure you can get a reasonable gain but it's cause the car is now handling good not that you created this tremendous amount of traction all of a sudden.

I'll get off my soap box now, lol.

I agree with you on that. But there are times when the track just isn’t there. Doesn’t matter how well the car is set up, sometimes the track is just slower. In those instances, I believe it does a lot. I think that’s really where the entire idea came from originally. And then, where is bad on the track because sometimes the surface itself is good in one spot and a little icy on another? If you had a digressive set up, it might be good on a track that has some good grip in the middle but loosing grip on exit.. you could fine tune the timing of the rate change and the pre loads to build a little more mechanical loading on the tires sooner, and then operate on a lower rate after a certain point where you need it. Or if it’s glassy in the middle where you’re running but there’s a bit of spot you can hit and pick up throttle harder a progressive rate might be better... What does entry look like compared to the middle or exit? How do you want this thing unloading? I think it’s not really going to push the car over the top like you said when conditions are optimum. Probably doesn’t matter what you have in there it could probably (not a nice word)(not a nice word)(not a nice word)(not a nice word) near be solid if the track was good enough. But the thing is, it is inconsistent not just from one race to the next but from one part of the track to the next in the same race at times. Or during a race even it changes quite a bit. That’s an entire other variable right there.
