How soft on front springs

springs

That stuff may work in the IMCA, and the sanction bodies that run the hockey puck tires.

hughes had a 600 in his RF at las cruces a few months back. I know he doesn't run it everywhere, but like most of the guys that run up front consistently, he knows that there is no one magic bullet for all track conditions. People got really hung up on running the softest stuff possible a couple of years back, but there are a lot of open shows being won on 550's and 600's in the RF right now. I'd say the majority of them most likely. We've won 4 shows (1 "big" and 3 weekly) in our new hughes car, at 2 different tracks. We're running a 500 on the little (very round corners), flat track, and a 600 on the bigger, higher speed track. Different things work for different people, and 400-450 stuff has it's place. But, I would never assume that a 400 is better than a 550 just because it is softer. You have to give the car what it needs for the condition at hand.

I would go as soft as possible, that way way everyone can brag to their fellow racers how soft their springs are.
Have any of you people ever figured the motion ratios, and what the soft springs rates actually compute to rate at the spindle? Then you put a shock on the RF with virtually no compression dampning, and a ton of rebound and hold the weight on the RF, when you do that, what spring are you unloading.....the LR.

On a 4 bar car the LR is loaded by the traction device and the bars 90+% of the time the spring is not even loaded. You can find chassis videos on Youtube where you can see that the spring in only in play when the car is off the gas going into the corner. The RF compressed gets the car in position for the bars to come into play the instant that the throttle is picked up. To make this work you must be smooth and trail brake into the corner and not toss and stomp.

Yeah, Just Add Dirt, what do you know anyway. You dont ever win any races do you!LOL

If your rf spring is so soft that when you lift you see the rf tire jump up over the hood and the car turns sideways, you wont have any traction regardless of whether the lr spring is loaded or the 4 link bars are standing straight up.

I think I can speak for JAD by saying You all should run as soft of a spring as you can get that way it will be easier for him to keep winning.

You have to give YOUR car what YOUR car needs. Every brand of chassis is different, every race track is different and every driver enters the corner different.

Like I said, do what your car needs, but I know the soft stuff works if you know how to tune for it.

I agree, but in IMCA, you can't get away with anything under a 500. It has more to do with a suspension setup in the back than it does just being a soft spring. Tires with more traction, obviously won't need as soft.

Hmmmmmm......I wonder why supers are running a 200-225 RF spring rate (stacked of course)

Why arent some of you mod guys doing it?

It can be done, as I have put one on a car already.

stacked coil overs are a whole different ballgame obviously...

[drtrkr244]

Each car will be a little different, so youll have to: 1)remove spring
2)back wedge bolt all the way to the top
3)measure from bottom of wedge bolt plate to bottom of lower spring mount
4)Search the spring mfrs to find 2 spring heights that will fit.

That should be enough info to get yall thinkin what you will need to finish it!

soft springs

I beleive you will find that you need a little heavier rear springs with your soft front springs. Before you change back to what you currently have try a stiffer compression right front shock if bottems out to quick. Also might have to raise ride height a little.

[washeduptoo]

Is a c/o on the front legal in the mods?

[drtrkr244]

Another tidbit of info; Just think of using the wedge bolt like a c/o.

[Egoracing]

Why stack em? I be likinG there idear of running 20" rar springs in my front... it shud wok grate.

You stack them because if you tried to run a single spring of that weight it will bow and twist and it will not last. We have run a 650 LF, 275 RF 133LR and a 225RR in a winning crate latemodel.

[drtrkr244]

I have not found any negatives to running a stacked spring setup. Once you get it setup properly , you just set it and forget it.They are not as temperamental as some people say they are.

There has not been many setup inventions that gives as many positives without the negatives.

You get the combined soft rate to get in the corner, and the stiffer bottom spring to get you off.

what mod classes allow more than 1 spring per wheel?
