'85 GSL

Hey everyone, so I've got my '85 GSL with stock brakes right now. I plan on upgrading the suspension some more, but I am wanting to focus on the brakes right now. I am wanting to road course it as well as autocross it. I am wanting to stick with the 4x110 bolt pattern on mine just because I already have wheels with pretty new tires on them and don't really have the money to do a rear end swap or TII swap in it.

I was wondering if this set up would work: Drilled/Slotted Rotors from Mazdatrix, Hawk Pads, Wilwood Master Cylinder and super blue fluid.

If anyone has any other suggestions or if anyone thinks this would be a good set up, please let me know, thank you.

If you don't have much money you could just get rotors pads and ss lines and just run dot4 . The stock master should be fine and dot 5.1 is probably overkill though ive never used it. At ss15 i raced my gsl all day at willowsprings with stock rotors/pads and dot4 and ss brake lines and it was fine. I also drove there and back ,its a daily

Yeah, I was going to go SS lines for sure, but I do want to upgrade the rotors and pads for sure though just because I want to push the car pretty hard without the brakes fading quickly. Each session I go out for Road Racing is about a half hour long and about 5 sessions atleast, so i really want them to hold up all day long. And for the master cylinder, my dad and i are wilwood dealers so I can get one for a good price.

Mazda rotors with SS lines and good pads and you will be fine. It's been awhile, but ds11 pads, no longer available, lasted through 4 track weekends and a year of driving daily. Negligible fade.

It seems like most everyone likes hawk pads for their setups. I was thinking of using the Hawk Blue 9012 compound pads.

Don't ever use Hawk blues on the street. Your rotors will disappear in days (weeks if you are lucky). I raced my spec7 and drove it on the street as well. I just changed back to stock pads for the street. It is ridiculously easy. The car is now a dedicated ITA car and I still use Blues for the front, stock for the rear. Never any fade. For rotors I just buy the cheapos from Napa (or RockAuto or AutohausAZ). Every once in a while one comes with bunged up threads, but rare. They last fine. Typically 4-6 weekends. Pads and rotors usually die about the same time. Drilled and/or slotted rotors are a waste of money. This is the same set-up we use on our chumpcar FB's. They typically last through a 14 hour race, so can't beat that. For autocross, I doubt the blues are very good. They need heat before they work well and don't chow the rotors. I just use stock pads autocrossing. If you are overheating your brake pads autocrossing you are using your brakes waaay too much. Lots of people also use Carbotech and our chump team sometimes uses a special Raybestos race pad (not sure the correct designation). No need to change your master cylinder either. Stock is right for the job. You might want to put a brake bias valve in, so you can use something other than stock pads on the rear. Blues on both ends of the car will probably send you into a spin everytime you brake hard at speed if you can't adjust the brake bias. You can guess how I know. It wasn't fun straightening out all the body and "frame" parts. Either time!
