Has anyone added a six piston setup to their car? I've been looking around and it's not to common. I need more braking power and I'm looking at my options. Car is a 98 itr turbo with a 84mm benson sleeved motor. I'm running between 330 and 450whp so I need great brakes as this is a dedicated circuit track car.

 

I run these on my R

 

wow, that took effort

 

atleast he didn't say your full of **** like me. but i say bullshit and full of ****.

 

wilwood makes a good inexpensive kit, you may overwhelm it if you're on slicks though

here's a shopping list of others

how much can you spend again?

 

What makes you think your running out of brakes?

I know of someone with even more WHP than you who runs stock brake calipers.

Look into SS brake lines, different pads. Stay away from slotted and drilled rotors as well. Change fluid to something like ATE superblue as well.

 

usually overheating an ht10 and glowing rotors are a sign that more surface area will help. stock brakes just start running out of fade resistance on slicks. most street cars are this way unless it's a porsche gt3, zr1 or some other car that has world class brakes stock.

 

Simply put, You are gay.

 

Around $1500, thanks. Are you using the wilwood?

 

My car dyno'd around the same numbers, and im on stock brakes, just hp pads, super blue brake fluid, and steel braided lines, and im stopping fine...

 

What tracks? From what speed are you braking? Hp pads are useless to me, how do you stop fine? Hp crumbled in my hands after one session.

never had them crumbled on me.. like i said i had no problems with them so far.. and ive ran the same setup up on my 00 ITR and now running it on my 98 ITR

 

some guys on here seem to think autocross puts the same demand on brakes as lap days LOL. i highly suggest posting this in the autocross/road race forum to see what they know as well. slowing from 140mph repeatedly takes a completely different type of setup than slowing from 70mph. for some reason the guys who hangout in the ITR section not only feel elitist, they often give out advice that's just plain bad. that said the wilwood deal is all 4 calipers and rotors with lines for 1500 bucks BUT the dynalite calipers are kind of like their baby calipers. i would be curious what wilwood would say if you called and asked about upgrading the front caliper to something bad *** like their integra 6 piston {yes wilwood has a caliper named the "integra" } see what they say. even they dynalite is a solid step up from stock.

 

if your car is stock i could see that. the corners are smooth enough you're still able to carry speed and you don't have enough traction to really stress the brakes. if you were on slicks, had more hp and drove on the brake / on the gas you would fade them after the first lap or two.

 

I have a Wilwood 6 piston kit that you can have for $500. I also have the rear kit if your interested. Both front and rear's are 12.9" rotors. I'm selling my ITR and took them off.

what calipers are those? dynalites?

 

Dynapro

 

that's a good deal for the OP

 

More pistons won't give you more stopping power, they improve modulation. More braking power came from larger rotors.

With that said, if you want more stopping power, any mini or compact 4 or 6-piston calipers that use the same size rotor would not be able to give you that.

 

and larger pads. the above suggested kit is a larger larger rotor @12.19" and likely a larger pad.

what were you going to point out wai? just that more pistons doesn't equal stronger brakes or?

 

What I wanted to point out is that more pistons don't mean more stopping power. Actually the stock single piston already offers enough "stopping power" to lock up wheels even with R-comp tires so there's really nothing to upgrade in that regard. So brake upgrades are usually more for better heat resistance (pads, rotors, fluids), modulation and unsprung weight.

 

exactly, fade resistance, i agree in that i doubt they would shave anything worth talking about off a single stop, BUT, the larger kits won't fade off lap after lap like the stock brakes can when you have more hp and more traction.

 

Don (mrlegoman) is using big Stoptech stuff on his turbo hatch. To my knowledge he's never had an issue with them. However, they may be out of your $1500 price range. A call to Brian at Fastbrakes could probably point you in the right direction. Keep in mind that with universal calipers like Wilwoods there are a lot of potential fitment/design issues (some calipers are meant to attach directly to a Macpherson strut, for example). Without doing the research or talking to someone who can decipher the information for you, you're really in for some trouble.

the Type R has tire limited braking -- upgrading the brake rotor size will give you more heat sink (which is good for track) but at great cost.
