    Adjustments heat to feature

    What are some of the adjustments you guys are making to tighten up your cars for the feature. Its a 4 bar metric impressive. The car is a turd in the hot laps but by the time the heats start it's pretty good. I don't want to be crazy and mess up everything else that's FINALLY working. Track goes slick every night.

    you might be just right..... don't make the mistake of tightening up a car that doesn't need it.... 95% of people race in the slick with too tight a car and have to slide it around, messing up the entry, middle and exit..... This was posted a long time ago on another forum by a Crew chief and chassis builder who said something like...
    I don't do a lot to tighten up the car much for the A main in the slick.... the Driver has 2 pedals and a brake bias adjuster ..........
    " Most of my drivers have been new to 4 link stuff and I believe most of their chassis issues are really my driver issues....... "

      air pressures and the brake bar are usually the only things we will change, and air pressures because we usually hot lap qualify and heats are on a real greasy track and the features are dusty dry

        It really depends on the track. If track is heavy for heat and slick for feature I'd lower both lowers on frame 1 hole , add fuel , and drop gear about 30 points for feature. Different drivers need different setups , there is no one answer.

          I was thinking adding 5 gallons of fuel and maybe 1lb out of the rr. I don't want to do too much and ruin what I have. I can finally race with the pack!!!!

            You may need more than 5 gallons of fuel if you run meth. If gas then you are probably ok with that. If its close for the heat i wouldnt change much maybe wheel offset or stagger. maybe a shock change

              1/4 or 1/2 spacer in the lr and/or shorten rs bars 2 turns.

                If it gets slick, usually fill it full "methanol" and maybe change tires to reduce the rear stagger a little. Other changes would be RF and LR shock change if it is really slick.
