Carrying the LF wheel
With everything in neutral on a 4 Link chassis, what changes could be made to keep the LF on the race track?
-
More RR spring, Less Bite, Limit LR thrust Angle for starters
-
Like 7 up said, LR thrust angle. ( shorten or add limit chain)
-
I had the same problem at the start of last year and i chain limited the left rear, i had to adjust a couple bar angles to get the car back where i wanted it, but it is handling great and keeping the left front on the ground 95% of the time now..
-
Thanks guys, also the rear tires after the race are crazy hot. Any ideas there?
-
IMO.....The rear tires are hot because you are lacking traction. A tire that is hooked up will remain cooler than one thar isn't.
-
Just curious what is your rear weight? Do you have wheel spin? How are tires grained?

Also if your front to rear balance is off fronts won't be as hot could also mean you need to add toe out its not uncommon on hard tires so your heat balance stays the same after a few laps which also makes your handling stay more consistent through out the race
-
my car carry lf more with stiffer rr spring.

Hooked tires, that are slipped to turn the car, will be hot.

We have very little tire slippage. The suspension geometry is configured to help turn the car without needing to slide the car.

That isn't operating temp for a lot of dirt tires.

Those were the temps from Friday right after the feature. I use a high quality pyrometer and check tire temps after every run. Car was very fast.

Are you also greenmod and accidentally logged in under your other screen name? It makes no sense for you to be posting your temps in a thread that has nothing to do with you?
I realize most of your posts are worthy of someone who must be anonymous that's why Im asking not just assuming...

Not to hijack the thread but since we're talking about tire temps those listed above seem very low compared to what I'm getting. I'm usually 110-120 LR and 130-140 RR. Is that considered too hot?

I dont believe anyone is going to say that is too hot. It depends on what tire you are on though. Call hoosier or american racer whichever you are using and ask what the operating range is

No I have no other user name other than Anonymous24Why do you say most of my posts are worthy of someone being anonymous? I post correct information that has been applied and tested on the track. Do you have a problem with me? J have no idea why you insist on being an a$$. Makes ya look ignorant. If you disagree with what I post, prove my information wrong with a credibile source. Otherwise, quit trying to stir up stuff when there is absolutely no need for it.

The tire temps on the Loose Gruff chassis we used to run were in that range. The tires liked to seal over under caution. I believe it was due to the high temperatures. I was always telling my brother to keep the tires hot under caution to prevent them from sealing over.

Tire temps depend more on the type of dirt and track surface, than type of chassis.130 is pretty middle of the road. Some tracks will get 200 or more.
