A lot of people use it as a safety feature in deep snow. Apparently it's better to lock up your wheels and plow than for the ABS to kick in. I dunno, I never had the opportunity to use it.

ABS Relocate
Relocating it is no real problem, but doing it right requires a fair amount of work and tools. Example in this setup.

I pull my fuse on gravel and it works brilliant but on tarmac the rear wheels lock first, you would need to change the bias or get some sort of proportioning valve before deciding whether you prefer the car with or without ABS.

That's a very nice set up and require a lot of work and tube bending.

As has been touched on earlier, remember ABS in the STI is tied to the DCCD, EBD, and trail brake assist all of which help you get the most out of your car (in theory).

I say do it and do a write up. We need one on here!
For a track car there is no need for it. Just dead weight. |

Ive always been told ABS can hide a bad driver, but at the same time ive seen guys that are using the ABS to there advantage. And with the knowledge on knowing how to use it its nice.

If you can never engage ABS then you either need to brake harder or improve your brakes. My current race setup will not engage ABS in a straight line, there is just too much grip and downforce. However if I brake late turning and cresting a hill like the back straight at VIR there is no way anybody could out brake the ABS system. The reason is that without ABS you would have to take break pressure off all four wheels (there is only one brake pedal) to keep the inside rear from locking up. It does take more skill to master braking without ABS but on most race tracks you cannot beat a modern 4 channel ABS system. Look at all the single wheel lock ups you see in F1, if they had ABS they would never have to come off the brake pedal to keep that one tire from locking up. You need more aggressive brake pads as a start if you are trying to have enough brake to engage ABS. |

Look up chase bays, they offer a super sick setup for deleting your abs.

I agree to keep the ABS. I tried pulling the ABS fuse for a session at my last track day, it was entertaining.... There was just no way that I could carry the same speed into braking zones that weren't a straight line without locking up a tire. Straight line braking was great though... I was about 2 sec a lap slower than my previous sessions.
Sorry to threadjack, but is the STI ABS pump different/better/less intrusive? I have an '06 STI 6 speed, with DCCD pro etc. and was wondering if that would be a worthwhile upgrade on my 03 WRX. |

I think I have decided to keep the ABS as it will help out in not flat spotting the tires if it locks up.
I wouldn't re-doing all the hard lines too so, what's cheapest tools would I need to easily bend and flare the lines if I want to relocate the pump? What size and types of lines can I use? |

I would check if the option for the dealer upgrade is still available which would help the abs action. The abs on the STi is really, really good for road race use. I just wish the bias was better! |

Those pre-flared lines mean you shouldn't have to mess with making inverted double flares at all. That's good, because they're a pain in the ass to form. When it comes time to splice lines, I strongly encourage you to use 37deg AN single flares. It's painfully easy to make a single flare (particularly compared to how hard it is to do an inverted double flare properly). I used steel unions, tube sleeves and tube nuts from Aircraft Spruce and a nice 37deg flare tool from them as well. A simple tubing bender (again, available at any auto parts place) is all you'll need to bend the lines. There are expensive, swanky ones that you can get from Eastwood or other companies like that, but I just used one of these from NAPA or Autozone or whoever. Worked fine for me. |

On my 04 WRX DD/recce/TSD car I have an on/off ABS switch. Its off most of the time except some snow conditions. (yes, on some snow conditions ABS is great)
On my 02 Rally car it came w/o ABS or power brakes, fully manual. Do I miss ABS? Hell no.... For the most part LFB and ABS don't mix well. |
