I am pulling 10 degrees for 1.5 seconds. Tightened front struts trying to keep the frontend down. It wanted to wheelie like crazy. It had some wobble side to side like a boat 1st couple passes. I tightened rear compression and it was good for 3 passes. The last pass it tripped the 330' with the rear tires and wobbled slightly after landing. I think it will be good when I get the front end to stay down more. I just changed from 4.86 gear to 4.56 for this weekend. The lack of tire growth picked me up about 250 rpm out the end so going back to the 4.56. I think with the 4.56 and some more tuning I'll be able to run full timing but time will tell. Lets also not forget track temp was 140+ last weekend also. I love the fact it never shakes the tire. I'm also taking the wheelie bars off for this weekend, hoping removing 35lbs from the rear will also help keep the frond down but hopefully not cause spin. [QUOTE]

Thanks for sharing your info on the PBR, keep us in the loop of getting them dialed in.

2BKING

29.5x10.5 PBRs @18 lbs on my junk. 6.40s at 3090 lbs. I found I needed to loosen my single adjustable AFCO rear shocks to allow the chassis to separate and plant the tires better.

Small burnout with little smoke.

I took it out with the 4.56 gear in it and testing was cut short so didn't get to try much. The car was not happy so I made a 4 link change before eliminations started. The car worked ok, again really high track temps. Once the sun started getting off the track the car was repeating very well. I made 15 passes through the 2 races that day and it had (radial wobble) on 13 of them including the last pass that got so bad it slowed me down .02 and ended my weekend. 60' varied .004 last 4 passes. Was actually pulling more timing than last week 12 degrees for 1.5 seconds just to be sure I could get down. I noticed when changing the 4 link the shocks were damp on top so I pulled them after the weekend and sent them to be rebuilt. Hoping this will resolve the wobble I'm fighting. I still feel these will be really good once everything is dialed in.
