roundthirteen Posted November 8, 2012 Share Posted November 8, 2012 So I'm looking at autocrossing next season and I wanted to know if it was actually worth it to do some of the smaller upgrades to my 08 Spec B's stock Brakes. I know good pads, proper bedding and bleeding are the key but are any of the other upgrades they offer for the stock brakes worth it, VS the expense of a full Stop Tech or Brembo upgrade?

SCASEYS Posted November 8, 2012 Share Posted November 8, 2012 ss lines I donated to LegacyGT.com which allows me to have this nifty signature. If anything SCASEYS posts ever becomes a sticky i'm gonna light this whole place on fire Link to comment Share on other sites More sharing options...
SCHM1AN Posted November 8, 2012 Share Posted November 8, 2012 Grimmspeed Master Cylinder brace has gotten some pretty good reviews from a lot of people. They say it takes a lot of the mush out of the pedal Link to comment Share on other sites More sharing options...
LosAngelesLGT Posted November 8, 2012 Share Posted November 8, 2012 ss lines Only if you need to replace your lines anyway. If your fluid is black, you need to replace your lines. I like the GS MCB. Link to comment Share on other sites More sharing options...

Yeah I was going to do the lines, I did them on my last two cars and liked them.

LosAngelesLGT Posted November 9, 2012 Share Posted November 9, 2012 Im guessing your last two cars were due for fresh lines. Are we are all in agreement that they don't really make much difference unless you are going from degrading lines to new ones? IIRC these are cheaper than oem and that alone makes them a good replacement option: http://www.infamousperformance.net/servlet/the-38/Techna-dsh-Fit-Subaru-Legacy-GT/Detail or http://www.infamousperformance.net/servlet/the-19/Goodridge-Subaru-Legacy-GT/Detail Link to comment Share on other sites More sharing options...

iggybdawg Posted November 9, 2012 Share Posted November 9, 2012 stock calipers should be fine for autocrossing. You'll find the limiting factor for our cars is grip, so spend your money on wide tires and suspension bits. Link to comment Share on other sites More sharing options...
roundthirteen Posted November 9, 2012 Author Share Posted November 9, 2012 So far I have fresh Bilstiens, H&R springs (came when purchased), a white line bump steer, roll center kit, and I've been looking at either White Line or Rallitech Sway bars with the AVO brackets. Right now I am using 225-18 Falken Ziex 912's for the summer. My car's not a sleeper it's a hibernator. http://pure-tuning.com Link to comment Share on other sites More sharing options...
iggybdawg Posted November 9, 2012 Share Posted November 9, 2012 Negative camber is your friend, and camber bolts for the front are cheap. There are two whiteline options to adjust camber in the back that aren't as cheap. Link to comment Share on other sites More sharing options...
Max Capacity Posted November 10, 2012 Share Posted November 10, 2012 Read the rule book before you make to many changes. Dunlop Star Spec's are your best bet. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

wpmarky Posted November 10, 2012 Share Posted November 10, 2012 +1 ^^ Auto-X rules explain what upgrades you can/can't do. I don't know the rules at all, but in general to improve high performance driving, tires first, then brake pads. Link to comment Share on other sites More sharing options...
N.sane Posted November 10, 2012 Share Posted November 10, 2012 Download the rule book here: http://www.scca.com/assets/2012_Solo_Rules_February_reduced.pdf Sounds like you'll be in STU. The first thing you want to do is TIRES! Falken Ziex 912 are all-seasons, so you're gonna shred them to pieces on an autocross course. The lack of grip will hold you back from having a good time too.

roundthirteen Posted November 10, 2012 Author Share Posted November 10, 2012 What about the AZENIS RT-615K? My car's not a sleeper it's a hibernator. http://pure-tuning.com Link to comment Share on other sites More sharing options...
robinlsb Posted November 10, 2012 Share Posted November 10, 2012 Read the rule book carefully. You will never heat up the brakes enough to make any difference in an autox. In fact, high temp pads, and brakes that require heat to work well, will reduce your times. "Belief does not make truth. Evidence makes truth. And belief does not make evidence."

N.sane Posted November 10, 2012 Share Posted November 10, 2012 The Azenis dont seem to a favourable tire in autocross. The 3 budget autocross tires that everyone uses are the Dunlop Star Specs, Hankook RS3, and Kumho XS. With regards to brakes, you can easily overheat them on an autocross course since our cars are so heavy. I would definitely recommend a pad upgrade.

I would definitely recommend a pad upgrade. I don't mean to be rude, but that's just not true. There is no way a 60 second autocross run is going to fade your brakes. We have large, vented rotors front and rear. I have gotten out of the car immediately after a run, and yes, the brakes do get hot, but I've never had a moment where I've overshot a corner because the brakes didn't stop the car in time. The fastest I've ever gone on an autocross track was probably between 50 and 60, FWIW. Link to comment Share on other sites More sharing options...
iggybdawg Posted November 11, 2012 Share Posted November 11, 2012 STX, not STU. Legacy is mentioned in the rulebook. Link to comment Share on other sites More sharing options...

The fastest I've ever gone on an autocross track was probably between 50 and 60, FWIW. No offence taken. I'm speaking from experience as well. I guess this could be subjective since it depends on the course and whatnot, but I've had several experiences where the brakes were not up to par during a run. STX, not STU. Legacy is mentioned in the rulebook. If it is indeed STX, my apologies. I'm just looking at the rule book and the only Subarus I see under STX are Forester XT and Impreza WRX. I figured the Legacy GT would fall under "Sedans & Coupes NOC (nonsports-car-based; 4-seat minimum; over 5.1L normally aspirated or 2.0L to 3.1L forced induction)", which is STU Link to comment Share on other sites More sharing options...

Either way I'm sure we can agree that if he wants to be competitive in any class, he should get some autocross pads like the HP+ or AX6, which coincidentally have a higher temperature threshold than stock or OEM pads. (knsbrakes.com, azpinstalls.com, infamousperformance.net, or fredbeansparts.com are all good places to start looking) You guys are both right. The Legacy GT was in STU prior to this season, but just got moved up to STX for the 2012 season. http://legacygt.com/forums/showthread.php/legacy-gt-moved-stu-stx-183035.html Link to comment Share on other sites More sharing options...
iggybdawg Posted November 12, 2012 Share Posted November 12, 2012 Yes, That just happened this past spring in a rulebook update. They somehow figured out we couldn't compete in STU. I'm moving my car from DS where I autocrossed it since new into STX. However, if you've cranked up your boost, that would put you in ESP, instead, since you aren't allowed to touch boost controls in ST*. In our region, though, we don't bother figuring out the classes of novices, we just lump them together in the Novice class and leave them without the pax modifiers.

AZP Installs Posted November 18, 2012 Share Posted November 18, 2012 Also the roll center kit may move him to a modded class. I haven't competitively autoxed a subie in 10 years, but when I did I remember roll center kits and ALKs always threw you way off. -Mike Paisan http://www.pbase.com/paisan/image/91072632.jpg http://www.pbase.com/paisan/image/145749898/original.jpg http://www.pbase.com/paisan/image/133406601.jpg http://www.whiteline.com.au/images/logos/perf1.jpg 11+ Years Maintaining, Modifying and Educating TriState Subaru Enthusiasts.
