im boulding my car little by little and i want get around 200hp someday maybe more but now 200 is my goal. my car came with factory 4 disk brake and now all my calipers are not working propertly so now im in the dilema of buying four new calipers and upgrading the brake lines and getting better brake pads. or is it better to do the swap since im going to spend money anyways. i might spend more on the swap and thats why i need to know if it does a BIG difference on stopping power knowing my hp goal. i know it does make a difference on cars that didnt come with 4 disk brakes and i know they are bigger than what i have but, with the brake lines the new caliper and new pads will that be able to do the job for now? thanks for looking any advice is welcomed
