    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..

            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

                    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...
