One post you said you have a 200 RR and another 175 RR??? You say your good in and at center, and no drive off. Tire pressures and need to find out about your shocks. A lot of throttle control on a slick track. I take rear steer out on a slick track. Idle your car at 1200-1300 rpm and see what happens.

That high of bite? Normally a higher bite will be loose in and tight off. With that much you will be loose in and so tight on throttle that it will throttle push. If the car doesn't go into the corner correct, you will have to try to compensate and most likely it won't respond mid corner and will be all over on corner exit. Try backing the bite down to 90# or 80# and leave everything else alone to start. Depending on other things, get the setup manual from the chassis builder and start there. From experience, even chassis builders when you talk to them will give you radical adjustments to use and if you are not ready for them, will create more problems. I would recommend starting out close to neutral and base then adjusting from there.

To adjust bite from setup and if you have a lot of LR bite you have to adjust with taking 1 round out of the LR, adding 1 round RR, taking 1 round out RF and adding 1 round LF. This will keep your ride heights close to setup. Adjust till you achieve the bite you want. Depending on what you have for the rear springs (sliders or coil overs), you may have to use the heims to do fine adjustments on the rears.

IMHO i would get atleast 20 degrees of pullbar angle. Also are you running a limiting chain on the left rear? If so i had the same issues you are having earlier this year. The chain was lifting the LR tire off of the track making the car snappy loose and no fwd bite off of the corner.

i would definatly run a steeper pull bar, i personally run a 23" biscuit bar and it is mounted fairly steep. secondly the rru bar needs to go down, not up. this will have little affect on the entry and middle but will give you a throttle push. has never let me down. if it is extremely dry i will switch my lr lower bar to a 2" longer bar at same angle as the short and that way the birdcage build timing quicker and more bite. i'm not a genius but these have worked for me.

Ran the car at two local shows this past weekend...wow did putting more angle in the pullbar work I had just the right amount of bite the car was so much easier to drive! And i even moved forward through some cars! With this being my second full season in a ump mod I need any and all help I can get but these suggestions were all taken into consideration! The pullbar seemed to do the trick this weekend! I was very happy with the car! Thank you

[Tnorton14]

Sorry i have not been on here latley....we have recently put a coil over on the rr and got rid of the eliminator...car is much better now i just need more seat time to get better at driving it....hopefully it all comes together by the end of the season

[dualdj1]

Glad to hear you're making progress. Keep it up!

Did you need to buy a new rear end mount to steepen angle?

[Tnorton14]

No i had one hole left on the frame to go down so we went down on thr frame and reset pinion angle
