BIG brake kit for race car

Postby Red 2f MX5 » Wed Jun 25, 2008 4:57 pm

Thinking of putting a bigger brake set up on my 2F NA racecar.

Anybody got any suggestions ?

Anybody had any success with something ?

Cheers

from what I hear the dynalite willwood based kits from goodwin racing have a tendancy to flex (CT knows i think). but that said the new version comes with dba5000 seriers rotors which is a big plus and they fit under 15 inch rims

If you go to 949racing.com they are in the middle of developing a big brake kit using the newer dynapro lug mount calliper which is a forged unit and should be much stiffer then the plain billet dynalite caliper. Its a few months off and should be around 1500 usd and can fit under 15 inch rims.

there is an ap racing front only kit but you need 16 inch rims and it costs about the same as the willwood kits which are front and rear.

there is also a brembo kit but you need 17 inch rims.

There is also an endless 6pot front only kit but you need 16 inch rims for those too.

no experience with them but they are the ones I know of.

The willwoods work fine on the MX5's...

QR is very hard on brakes so you should think about doing something before you go if you want to upgrade the brakes...

I will put something on before QR if i can.
Nick has offered me his old Wilwood set-up he had on his turbo car. He now has AP on there.
It's front & rear. Calipers, dog bones, discs and hoses for $1500.
I saw on the Goodwin racing site they do kits new for around that type of money.
Will i need to do a peddle box to get the bias right, or just play around with pad compounds.
I thought if i just do fronts it will probably be to much front brake and just lock them up.

A lot of people up here who have tried Wilwoods and other big brake kits have had the same problem. I really don't think they are necessary. Almost all of us use the standard NA8 brakes.

I have tried acouple of different brake pads.
I found the Hawk blues were real bitey and locked the fronts real easy. I was talking to CT and he said get rid of the booster. I may do that.
I now have EBC yellows in the front and reds in the back. I find that much better, but is the total opposite. You really have to stand on the brakes. And they don't lock up.

I will do some thinking. Probably just run it the way it is for now.

check out the carbotech pads www.ctbrakes.com

I have done a little reading on the miata.net forum and the race guys over there think they are pretty good. They have a pretty comprehensive range of racing compounds and if the talk is correct they are easy on disks and have good pedal modulation. I am going to get some of the xp10 compound for the front for track days. the popular combination is the xp10's on the front and xp8's on the rear. I think in the spec miata class they run stock callipers (not really sure though) so they should be enough.

EBC are crap....the Hawk Blues are the best...it's just a matter of getting used to how much pressure you put on the brake pedal...I have no trouble outbraking just about anything.

I probably just needed to get used to them. I found you could only use a little bit of pressure otherwise they locked up. i was a bit scared to go in deep in case i just drove off the track or into somebody.
I don't mind the EBC pads. I find they had pretty good feel.
But the hawk blue's had better bite and it probably is just a case of me getting used to something different.
