first of all, a satria is not design for putting in a 4g63t but nonetheless malaysia boleh!! as in many has done it!!
alvin, putra's and satria's on track are running on n/a which make them easier to handle and playing with the revs to complement the weight ratio of the front and rear, whereas tebo's on d other hand makes your car go forward without helding back the force hence reducing your tenency to control your car hence losing control, which i happen to see at SIC, was behind a putra tebo in corners, his car turn 180deg cos he go tekan in one of d corners.
everybody knows a tebo has too much power too handle on corners and not everybody can handle it wisely, unless u are on 4wd then different cerita la
yes 63 engine is heavy, and ur whole front goes down cos of d weight but wat like acbc said, put something at the back to handicap its weight difference. putting adjustables or watever expensive abs at the back is definately not giving u d best offer of security cos watever it is, a satria is too light, same goes with my own, once in SIC.. the back give way also.
but there are few things that u can do to improve, your tyres at the rear which is the most important, your ARB and your UR bars.
