Ok guys, I知 looking for some assistance. This forum seems to offer a lot of good information, so I知 hoping you can help me out.

My car is basically a Limited Late Model. It has a stock camero clip and lowers, tubular uppers, 3 link rear with no rubber or spring rods.

LF: 685 RF: 690
Lr: 760 RR: 740

LF: 950 RF: 1000
LR: 250 RF: 200

Short panhard, even with drive shaft up 3 inches on frame. Left bar angled up 2inch. Right bar level. Both spring behind.

The track is a short ス mile with big corners; always slick. The problem I知 having is lack of side bite at the center of the corner (4 wheel drift). Car is good driving into corner straight, but driving hard it drifts. Last week raised ballast above rear, that helped a lot, but not enough.

My past experience is 10 years in a sprint car. My last time in a full body was 1988.

Any suggestions would really be appreciated. Thanks!

Try going with a softer rt front spring will put more traction on R.F. and let car roll over more

I would say that you need to get into shock tuning. Weaken rebound on lefts and weaken compression on rights till you get her where you want her. I hate that neutral drift stuff. I would adjust the rebounding lefts first then the compression on the rights.

speedy5 what do you have for the third link? Have a car like that also an it has a spring bar on it. The lower links are 10 degree up at the front an the spring bar is 15 degrees down.The best setup that i have found for this car is 55% left & 55% rear an 53-54% C.W.1" stagger on front& 3-4"on rear. L.F.1000 R.F.900 R.R.250 L.R.275. The total weight of this car with driver is 2650 an all setup is done with driver weight in seat. Have used softer springs on rear but works better with the stronger ones on the dryslick.Have to run weight up high for car to roll over an get good side bite. The lowest ballast is 12-14"above frame an when needed i have two 25# pieces that i raise as high as the drivers chest one right behind him on the cross bar & one to his right.Also have found that the j-bar works better than the short bar an it is 271/2"long an mounts even with pinion an about 4-5"up on frame.Also this is with hoosier tires an the air pressure is R.F.10 R.R 8 L.R.6 L.F.8 Do not know if any of this will help you but we run just about the same type car an track an this has worked good so far. cd2

My advice: Soften both front springs 100 to 150 lb to loosen it up going in, and move pan bar below drive shaft to get more roll and side bite to offset that. Rear % is under 53%, I'd add more. Get it up to 56-57%, should help with rear bite. Move LR spring in front Leave RR behind and rescale.

I'm with mod70 , lighten up on the front spring and stagger the rear, i know on my mod the staggering of the rear springs sure made the mid turn tight as can be to a point of pushing the front from the center off.

Thanks a lot for the information you have given me. I should have given more specs in my original post. I値l add them now:

Wheel Offsets and Pressure:
LF: -3 10 lbs RF: -4 14 lbs
LR: -3 10 lbs RR -5 12 lbs

Shocks are comp/rebound:
LF: 5/3 RF: 4
LR: 4 RF: 4/6

Our spec tire is Hoosier 28 or 29 x 10.5 - RC0 compound
I bought the car used, race ready, so now I知 fine tuning it to my driving style.

Changes I致e made to the car so far:
RF Spring 1150 to 1000
Both rear springs down 50#痴
Panhard from right to left side,
Raised 80# ballast 12 inches in rear

Considering these changes raising another 40# at rear RF Spring to 900 rr spring to 175 and raising motor and tranny 1 inch as this would only require spacers ad longer bolts.

Again thank you for the information!
