Default upgrading brakes

finally upgrading my stock (1.8) brakes, stock pads are due for a replacement and I'm looking to get street/mild track pads, steel braided brakelines and fresh fluid

probably going to use porterfield R4S pads, with the braided steel lines from good-win-racing (website seems done?) and dot 4 fluid (or dot 5?)

mostly street and mild trackduty about every month (Zandvoort )
what fluid should I go for?

and how about rotors? my stock ones are still in good condition, so if I don't necessarily need them, I'll wait before replacing them

funny thing is, pads, lines, fluid and possibly rotors too, are cheaper for me in the US, even including shipping, than from europe

use a DOT 3 compatible fluid, like a DOT 5.1 fluid.

ATE sluper blue (500F)

Amsoil Series 500 High-Performance DOT 3 (400F)

Valvoline SynPower (500F)


get cheap *** NAPA blanks or resurface yours.

I've had very good experience with:
http://www.raceshopper.com/hawk_brake_compounds.shtml
I run Hawk HPS on my daily/track toy, ATE blue, and Goodridge lines. I'm not boosted, but so far, I haven't had any issues with fade, or rotor life, and pad life has been excellent (7K street miles, 12 or so track days, down to about 25% or so).

Amsoil Series 600 has a 580F dry boiling point and around a 420F wet point.

Yes, email me soflarick at bellsouth.net, give you a deal. You can get it by individual pints or by the case. I am trying to see if they'll start selling it by cases of 6, since cases of 12 is a little much for most of us. It's got the same boiling points as Motul 600 (I think the dry point is 5-10 lower on the Amsoil, but wet is the same) but is half the price.

I've been using ATE Super Blue, and once my last 2 liters are gone I'm switching to Amsoil 600. I've got to swap front calipers and do a complete flush of the brakes and clutch so 1 liter will be used up right there.

Screw street/track pads. Because no pad will do either as well as dedicated ones will. Same as 'all weather tires'. For track duty, check into Carbotechs. You're still NA so XP8's will do fine.

I think with Carbotechs, not 100% sure, you can swap around the compounds and not worry about the boundary layer on the rotor being an issue since the pads are made of similar components. Plus it seems even aggressive Carbotech pads aren't super aggressive to rotors.

If I needed front and rear pads, I'd just go with the Carbotechs. I have a couple sets of Cobalt GT-S pads for the front and HP+ for the rear, so once those are done I'm giving the Carbotechs a try.

stay away from the R4s for track, i've heard they crumble from track guys. i do run em on the street and never had a problem. actually had em on my car on the track once and they were fine, still are fine. about 100k miles later.

That's because by the time you install them, they've already used up their aggression on your wallet.

Maybe yes, maybe no, I'm not sure. I keep my track rotors, with my track pads, and my street rotors with my street pads. If you're swapping tires and pads anyway, rotors don't take much more time.

Also, I've driven home (a few hundred miles) on XP8's with no problem.

Carbotech's are expensive, but you appreciate it every time you hit the brake pedal.

I can't (and won't) swap pads and rotors every 3-4 weekends, so for now I'll have to compromise

soflarick: thanks, I'll shoot you an e-mail soon


done, let me know

I have axiss ultimates, they were $80 shipped on ebay for all four sets. Used new rotors at the same time. I haven't raced the car though i hear ultimates are crap for the track like the R4s, possibly chunking. For the street they're great though.

The R4S's are probably going to be more aggressive stoppers than the Ultimates. Ultimates are nice street pads that can handle light track duty. They dust quite a bit, but are quiet and seem to last a while. I used to run them on my car until I got a big brake kit. I didn't use the brakes very hard on track as I was a novice.

funny, people here swear by r4s's or ultimates for light to medium track use on a streetcar
I can live with a bit more dust and noise, but need pads to work good both on track (novice-level) and street
