i have now fixed my tweak...
for the front...
when i bought the aluminium front anti rollbar, it came with these two flaps which connects before the arms... these flaps me thinks adjusts the tension travel of the arm... so i adjusted them so that both arms travel smoothly... and because i made sure that the single hole piston is at the front and made sure that all shocks are equal... it then did the rest.... so my tweak is now dead even...
for the rear...
i took on muugens advice and lengthened the shock which lifted the wheel first and extended the actual shock cap... and that did the trick... now my car has no tweak at the fron and at the rear...
thanks for all your help peoples...
