Ok, here's the deal. I am going to do a disc brake conversion to my 93 Sol S (money is the deciding factor of when). However, my questions are these: If I'm going to the rear brakes off of a VTEC sol, do I need to do the 15/16 master cylinder? And if I do,(or if it's just highly recommended) do I also need a new proportioning valve and brake booster? my bro(lsvtec) said to talk to the people that have done this swap before. Just let me know how you guys fidured it out, and your results.
