Default TC3 with BMI chassis

Hi all, I'm having lots of trouble with my BMI chassis car. The rear of the car is comming around whenever I turn into a corner. Right or left the same problem. I'm running on asphalt with purple foams all around in stock.

The shocks have 35 weight oil and I've tried several spring combinations as well as adjusting the diffs and trying a one-way. I've checked the tweek and ride hight after each suspension change to be sure the car is balanced.

Any suggestions are appreciated.

Chris

<<Have you checked the droop?>>

Yep set per the manual.

<<Run with no rear sway bars, copper front springs, blue rear springs, 50 oil front, 40 oil rear.>>

Thanks I'd tried blue on all four so I'll try your suggestion.

<<Try running CS-27s or Sorex 36Rs.>>

Ok I've got some 36Rs so I'll give that a try too.

Thanks to all for some different setup suggestions.

Your car simply has too much front bite, when running foams you generally run a different compound up front. In australia we generally use gas compounds which are denoted by shore.

Most people in stock run either 42 shore on the front, 37-40 shore on the back.

I believe Purples are 40 shore, so you need ot go harder front tire. You can also try the front only compounds many companies sell, they will have less bite than the equivalent rear compound.
