RR spring ?

[Matt49]

Shortening the right lower bar will typically tighten the car overall.

What spring do you have in the 5th coil? We always had to run a 350,in the slick, in the first hole, just like the supers!Also, we lowered the jbar into the lowest hole on pinion and indexed the lr top rod on the birdcage.

Whats a "pogo" LR? Where are your lap times? This bump stop RF, dynamic load measured or just put a bump stop in it? I don't know MB car's droop range, but you may have too much droop in LR, the extra roll steer can really help you roll the center..or ruin you. "Burning up rr tires" either your too tight in and thru center and sliding the car to turn it ( what I'm suspecting ), or it is truly loose center out. Tough call without it all (accurate detailed info and video). HTH CC

High compression/low rebound with a traction shock....all 4 shocks from Advanced valved for
that car 13" of droop which is what mb calls for.

So how do your laps compare. Track use transponders? If so what track? Some older cars don't have RF frame/crossmember ground clearance needed to run some of the later type setups. I don't know MB specifics. A 300 rf spring better have a properly setup bump stop . Lower HP cars like lighter LR springs, help to keep roll/hike in car when track slicks off. The knee jerk reaction is to tighten the car, because it is loose off, when usually too tight in/apex is the problem. Are other cars still flat footing in the slick?

Put 5 gallons of gas in it, add about 1/2" of drop, and put a right rear tire on the left rear and go race
