car is perfect when track has just a little tack,just need to be a touch tighter from center off when track goes black and dry.
rr tire is pretty warm 150 degrees ,after feature,rest of them in the 110 range.

some ideas would really help thanks. 2 heat race dominations-2 feature seconds so far.

Have you tried taking some stagger out?

How much bite? Maybe try raising the rear percentage up just a tad to get you what you need. Good luck.

Sounds like you could do a couple of things up the left side, up the cross, and up the rear, and raise the ballast in the car. How do you like the front springs in your car? I know alot of guys are running quite a bit softer aroud 800 or so. Let us know what happens.

front does great ,gonna take away some stagger and maybe move rr in a little.

go to lower front springs. with out weight transfer front to back how can the car hook up? try a lf 900 and a rf 800 this will allow you to get on the fr better and will let weight transfer to the rear coming out.

how old are your tires?

okay then id maybe try throwing a set of softer springs in the front of it with the stiffer on the lf,

More rear weight!!! Leave the front springs. Put a block or two of lead in the rear come feature time. Once you have established what amount works, put it on the scales and take note.

I would reduce stagger first. if it helps but makes it tight in,reduce cross.

From the rear tire temps i would add like 30# of left rear bite. This will help the car
on entry & hook it up better off the corner. If need be space the R.R. out some on
the tacky track if the added bite makes it tight through the center & off or up the stagger
maybe another 1/2" then drop it back down on the dry.

We ended up moving the rr in 2" ,taking away stagger to 0,put a easy up shock on rf,and a easy down shock on lr. Won the heat race track went slick made these changes car was awesome led it from the start to about 6 laps in had to pull off with oil pressure issue,but he said he had lots left no one was gonna beat him.So,maybe we learned something despite the bad luck.Thanks for all your help and suggestions.
