Running this car on a 11.5T motor on a medium traction track and having problem getting the rear end to sit tight on tight turns with Sorex 36R tires. Have tried increasing the roll center and 3 degree rear toe-in, spring rates, damper oil etc with little success. Needless to say the car has lots of steering, too much in fact.
Running our of ideas. Any help appreciated.

I m running sorex40 with med type C inserts, with stock 2 deg toe, 3racing black springs all around and Much more 500 oil. Everything, seems to fine, my only problem is turning into tight right corner when if not careful will break loose at the rear. At the moment i just reduce the right steering throw a bit and it seems to be ok now. Try harder springs at the front maybe that will help a bit or decrease rear droop if its oversteer off power.

I would suggest increase rear camber to say 2 degrees, and go to the 3 degrees toe block, or at least get the negative half front block to attain 2.5 degrees.
Also, i think the kit setting for the rear camber link is in the outer hole on the hub, go to the inner, this should lock in the rear end.
I would suggest not going to harder front spring, i always find changing one end without the other really affects the balance, like the car is fighting itself.
You could also be finding the car is overgripped, try raising the arm moutns with spacers, start at 1mm and see how it changes the feel.

dameetz and old-man, I had the same problem you guys described and I played with the rear camber link and rear camber to resolve the issue. Try adding more camber gain in the rear to keep the car from rolling too far over on the tire thus breaking the rear loose..

Teach you going to Fredericks race in 2 weeks? If so I would like to take a look at your new Zero. I know me and Steve are going to Trains and Lanes race this weekend.

update
hi all
pleased to say after the weekends racing the cars are planted and well on the pace my friend was just knocked out the A finals by 00.3 off a second with a mistake during the run :0(
I was bit lower down the b finals due to making too many changes to the car during qualifying and on the last run the rear upper link come unscrewed
but car was flying in finals after changing most things back to kit
what made the biggest difference was adding 0.5m to the lower roll center all round and changing the droop settings to 5 rear 4 front with 5 mm ride height
3 deg rear toe and less front camber car felt so nice to drive
seems the car likes hot tires as well much more consistent during five min run
