Hey, that's right...... my mtx4 has understeering tendency too at mid corner. And it can understeer even more if I enter the corner too fast. I have to let go the gas quite early, so the car won't overshoot the apex. Oh well.... I haven't find the perfect setup yet ......, coz other cars ( without this problem ) are able to whoop ass

Perhaps I should consider cutting lower rear and front suspension arms to make it short wheelbase.

Currently I put 60,000 diff oil in rear, and I haven't test it yet.

I'm speculating the mid cornering can be tighter after using 60K diff oil.

use less downstop for rear ( lets say from 4 to 3 ) and/or do the opposite for front ( lets say from 0 to 1 ) <----- 4th

use 3 degree toe in for rear tires <----- 2nd

lay down the rear by one more hole <----- 3rd

use fresh tires <----- 1st try

Got to drive my mtx4r for the first time and it was decent out the box...Had a little push mid/corner out on power but other then that it felt great.... I was able to go in hard but had to brake hard to keep the push down..

Does anyone know what shore the stock tires are?

When you say less you mean more droop? Lower number on the gauge?

Have fun with the box setup. Save yourself the headache and change the rear lower pins to the middle or up position.
