Is it just simply adding weight to the rear? Do I need to look at lighter rear springs or shocks changes.
Springs LR 250 and RR 200
Shocks PRO WB946 LR and WB95 RR
Rear % is 52.5%

Our set up for dry-slick lr 225, rr 200 springs. Shocks are wb 94s both sides. what shocks are you running up front? We use lf wb 95, rf wb 96. A softer or ez up shock on the front will aid in weight transfer. Your rear % look good. IMO, I would try shocks and or springs before adding any weight. What about tire pressures?

Drop the mounting points of your lower trailing arms at the rear end. I like to put a shorter arm (3/8") on the right side to tighten it up. Use all the trix!

Trailing arm angle is 18 degrees now. That's pretty steep. You can feel the rear raise up as I shift into drive.
Front springs and shocks are 1000 LF, 1100 RF
Both front shocks are PRO 76.
We have to weigh 3,000 and mine is 3,170.

Rear spring weights? Shocks?

Try this shock package : 76-2 RF, 75-3 LF,94 RR,93-5 LR, Try lowering your rear roll center. If your minimum weight is 3000 get it as close to 3000 as possible. Remember the steeper the angle's on the arms, will result in quick hook up but not last as long were as a not so steep angle will make the hook up last longer but not come on as quick. Keep us informed on to how you make out. Good luck !!!!

this is a common question and we always forget to talk about one of the simplest forms of traction control (our right foot).
the better drivers are very cautious and alert to the sound/feel of their cars as they exit the corner. your numbers dont look any where out of the norm so try a little more feathering that throttle, it may help. course you didnt talk about tires at all, they are the last point of contact and your foot is the first.

Hey Eljojo, Rear info on my first comments. Feathering is good but the more the pedal is down the faster we go.

The springs and shocks look close...maybe move the right over to the left and put in a 175 on the right...??? I'd see if I could borrow one for a night and see.
IF not, drop 75 lbs in the rear. At this point I'd bolt it near the front of the fuel cell, to the left of center.
Keep us posted!

What do you want for angle on your lower control arms?

you might try a stiffer right front spring! we ran on our metric cars LF-1050 rf-1250 LR 200-225 and RR 175-200. Also try getting more rear % in your car also! We ran the wb95 across the rear for shocks!

Car was best it's been. Still "Late Modeling" it down the straight.
Late Modeling - Spinning the wheels.
This weeks adustment was 100 pound heavier LF spring for the push in and loose off and 50 pounds of weight over the LR frame rail.
Next week adjustment will be 50 more pounds on the rear. I'm thinking of lowering the trailing arm angle from 18 to 11.
We finished 4th in the heat and 5th in the feature this week.
