I plan on buying the Cusco front strut bar and lower arm bar and was wondering if it would be ok to install them right away without doing anything at all to the back suspension... Would this completely unbalance the handling characteristics....
or should I try and get all the pieces and do it at one time..... Thanks ahead for the info...

 

i think if you did it at the same time the car would remain neutral while cornering...if you just do the front it will probably oversteer...but i might be wrong about that
