Mastersbilt setup

[hunterracing]

Looking for setup help on 08 mastersbilt in the slick on wrsd55 tires springs lift arm location and spring rate plus bar angles and lead location

Mastersbilt has that info on their web site. We started this year with an 07 square tube, went to Mastersbilt school and our setup is very close to the book. Second week with a green driver started in the back and finished fifth. Mastersbilt ROCKS!

What are you running for shocks? Are you siping your tires? Both make a HUGE difference.

What does the car do wrong/not do right?

[hunterracing]

Soon as I turn the back end get side ways on me and I can't drive it in as deep as the other guys because the back end slides up the track and then spins down the straightway that's y I was thinking goin to the 325 right front and mayb changing the lr to a 200

Based on your setup, i havent seen you drive, i think you are too tight on entry and forcing it to turn with the brakes.

[hunterracing]

I thought that to so I raised right bottom it was worse

MB Racer is probably right. I bet you're "snapping" the car loose going in but I could be wrong also.
The S7 deal tightens the car up quite a bit also allows it to also steer positive (that's been my experience anyway).
Get that j-bar up off the bottom of the pinion!!! I don't think you should ever need it that low even on hard tires. I would put it at pinion height and maybe even move the chassis side down to 8".
This will free the car up on entry so that you won't have to snap it loose to get it to turn and you'll have WAY more forward bite coming off if you get some of that angle out of it. That's where I would start.
Maybe just move it up a couple of holes on the pinion so the change isn't too drastic. Even with that much change I think you'll see a huge improvement. J-bars have a sweet spot and I think you're just out of it right now. All the 4-bar changes in the world won't band-aid it.

I'm not snapping it I'm. More of a straight line driver and. Not a throw and go what bout the rest of my setup the lr was index and I took it out last nite for this weekend

[MasterSbilt_Racer]

Your front springs should make it TIGHT on entry. I agree with Matt49 on the j bar as well.

What bout spring rates and lift arm position and lead location
