o dear, cut springs are not a good idea if you want a car to handle, in fact the ony way you could make it worse is by removing them completly!
cosmo: i can help you out here, you have several options, it all comes down to budget in the end. i can do a complete TRD kit for around $12-1400, thats a top-of-my-head figure, it will depend on specs you want etc.
send me an email and ill send you some info. i can also get whiteline, bilstein etc etc
its perfectly possible to lower your car and maintain a good ride, just needs some planning and careful choice of product
