upgrade vs value


roundthirteen

Recommended Posts

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?

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:

The first car blew a line and I just decided to upgrade, car #2 I was upgrading the front brakes to aluminum twin piston calipers and needed the slightly longer lines.

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.

Download the rule book here:

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.

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.

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 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.

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 :confused:

Very true- no two autocross courses will be the same. 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.

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.

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.
