First year in a Shaw, I have no drive off the corners on a dry slick track. Im on IMCA tires. The issue with me is Im 6'4 285 and I have always had trouble hooking up on a dry slick track. The car drives good and will turn and go where you want it, it just doesnt have any drive off the corners with either tire. I also have a chain on the lr, should I just take it off reason being is the car just doesnt seem roll over on the right side like the other shaw cars that I race against. I'm also not getting very much lr hike either.

Bar angles
LTB one hole down from top RRB third hole down from top
LLB second hole down from top RRB Third down from top.

Springs
600 600
175 175 (16 inch springs in the back)


Pull bar 1200 spring, mounted bottom hole on chassis

ride heights are
8 1/4 7 7/8
11 7/8 10 1/2

Weights %
no driver
535 468
653 676
left 50.9
CR 48.1
Rear 57
RR%-23

W driver
638 451
773 768
left 53.6
cr 46.5
rear 58.1
LR % - 5

Any suggestion? Im going to call kevin on Monday, I just wanted to see if anyone else, was my size and shape and having good luck running a dry slick track.

I would think with your built in L side you need a stiffer lr spring to help hold the wt over on the rr when it does transfer.What shock's ?

Looks to me like you need some more lr bite. Looks like you're only making about a 20 lb change when you get in the car. I would try scaling it with 10-20 lbs lr heavy depending on how bad your traction issue is. You also might want to look into lowering your j-bar both on the chassis and rearend equally a 1/2" will be a noticable change. When doing this it should lower your roll center on the rearend and help lift up all that driver weight and transfer it over to the right side.

Also as mentioned you might want to try a 200-225 lr spring. Just curious why do you have a straight 1200# pullbar spring? I haven't tried a straight rate but Kevin sells a 700-2000# Progressive rate for his cars.

We have an 06 shaw and had a straight 1200 with an afco 3 way bar went to kevins 700-2000 spring last night and the car had the most drive off we have ever had.

what about taking the chain off the Left Rear???

without the chain you may get too much hike up or droop in the LR. causing the car to 3 wheel like mad. We had to chain ours to limit hike otherwise we could be carrying the left frotn 12-14 inches off the ground the entire way around the track.

The 1200# pull bar spring is not letting the car get any initial bite in the dry slick. I would change to a progressive rate spring.Everything has to be smooth in the slick........ Good luck
