Suspention/tire unbalancing

Okay, im the type that loves to powerslide around turns and slide everywhere in general, i've come to find that this is the cause for my front end shaking, it has cause something to become unbalanced. Basically what im trying to know is what should i upgrade so that i can afford to slide around turns and just slide around in general with out damageing my car at all or reducing the damage done by the's powerslides and such. do i need to get new coilovers? different tires? ect... any help would be greatly appreciated.

Do you do most powerslides on the gravel? if so you may have dirt on the inner rims making it unbalanced. Another thing it could be , if you do e-brake stands the rear tires lock up and wear a flat melted patch on the tire and will make for a un smooth ride.
