LF Spring Theory

[CCHIEF]

Tell us why a lr bar adjustment is a bad idea. (no sarcasm)

[MBR Performance]

First I never said that a LF spring change is the "go to" adjustment for throttle tight. Second changing the rod angle has to many other effects on the car. The better option would be to remove some LR drive which would help the throttle tight condition and a lose entry condition he should also have with being so throttle tight without affecting the roll steer of the car.

the left front spring is not as crucial on this posters car with the rt front set up he has, but, I've found it to be a lot more significant with a soft spring/bump stop set up on rt front where there is more loading on left front..

Thanks guys... Track conditions were the same.. Track might have been a little faster the week we won?? I was really just wanting to know if I went the wrong way with the LF... And looks and feels that I did...Ill change it back... Maybe drop the wedge down, trail the rr bars 2 turns...my 4bars are already set for the car to be free...

If your entry wasn't bad I would leave the LF spring in there and just adjust the wedge. Don't throw to many things at it because you won't know what adjustment changed the car if it doesn't work

So last week I had a 500 on the left front... We won the feature, but the car was tight on corner exit on the gas as soon as I would pick up the throttle...Sometimes I would drag the brake off the corner to keep the nose of the car down till I could drive the push out. I have always thought that a softer LF spring loosens the car off the corner and of course stiffer LF tightens off. So this weekend all I did was soften the LF to a 450. Everything else the same...Same track conditions...The car had a terrible throttle push all night. 10 times worse than the week we won?? It was undrivable. I could enter the corner perfect, have the car turned to come off, but as soon as I would pick up the throttle the car would take off to the wall...Should have changed it back, but I didn't. So my question is...Did I go the wrong way with this spring?

Your messing with the wrong spring, but if changing the LF made entry and center better I'd leave it alone and look elsewhere.

I would expect it to be tighter on a faster track. A stopwatch is a good tool for judging if your up to speed with the best cars that night. One thing for sure is when your out front you can let the car go where it wants to, which is almost always faster than pinching it off somewhere(all them darn moving obstacles on the track!). When your leading those following need to make a better lap time than you to get past you....and/or steal your line (make you pinch off car). Congrats on your win, hope you get more. If I can be of assistance, feel free to ask.... I'm not trolling for customers. What year make and model of car do you have? Where do you race? If you have a travel limiter on the LR bar adjustments can benefit your deal.

[Aces&Eights]

Why not just shorten the travel limiter on LR a bit?

[MBR Performance]

You do it your way and I'll do it mine.

[RCJ]

Is the track you race on high banked or flat?A Real flat track where the l/f is wanting to unload vs. a high banked track where the l/f sees more compression, will make the car react different to the same change.A l/f change can effect how the car is rotated in the center.When you go to the throttle the car is not rotated enough to get a good line off the corner.

[Kromulous]

We tried the 50lb drop on the LF, 500 to a 450 and it did what was described. Car stayed square off, and drove straight off the corner better.

Side effect was, it loosened entry in 3 a touch, and he couldn't hardly hold it on his line in the feature. 1 and 2 was fine, but that end of the track is shaped different.

Anyway, good adjustment thou, may try with some rebound added to the 5th coil, to frim up exit just a touch.

[MBR Performance]

Can you describe the problem? Was it loose on entry on or off the throttle? Was the RR trying to wash out?

[Kromulous]

Off throttle, going into 3 at Florence Speedway (North South track) i know alot of you are familiar with it. I want to say the RR was washing out a little. He said he basicly let it slide up to the wall while dropping speed until it firmed up. Then could go.

250lb RR spring.

1 and 2 was good, to a tad tight, but could drive thru it.

Gonna try a LR stack this week i think, and use this adjustment again in the feature. Were trying to learn some trail braking too, which i think will solve it. That and some rebound on the 5th shock.

turn 1-2 had some brown dirt up top to catch you last weekend 6/18, I was experiencing the same issue with my modified
could not get into 3 as well as 1-2. had to slow down a lot more than usual because there was no cushion left to lean on. then middle off there was some good dirt left up top. 1-2 had cushion entering and threw center and went away off 2.

Krom why are you going to a LR stack?
