Tubular K-member, A-Arms and Coil-overs

i am wanting to put a tubular k-member, a-arms and possible coil-overs on the front of my car. if i get tubular a-arms do i have to get coil-overs?

which is the best brand of k-member and a-arms? a friend of mine put a full QA1 setup on his car and it moved his wheels up a little causing him to only be able to run his front runners, he could not get his 16s on there. i am going to be running 17s and i want them to clear, i dont the wheelbase to be moved any?

so what kit should i buy and also if i have to get coil overs what spring rate should i get? this will be going on a street car but it will also see some track time, i just want to lighten the car up and plus the tubular stuff looks a lot better

awesome, thanks

i was really looking into the D&D kits and was hoping someone would post about one, thats what i will be going with
