Rhitter Posted July 13, 2016 Share Posted July 13, 2016 From this thread - http://forums.nasioc.com/forums/showpost.php?p=44366274&postcount=532 This is actually the post I meant to link (that one just confirms his car) http://forums.nasioc.com/forums/showpost.php?p=44377887&postcount=538 This user has the same issue I do with the rack and he has a 2012 WRX. According to cars 101, the 2012 WRX has a 15:1 rack. He found the only fix was to turn off traction control (what I am currently doing) All the legacy guys are slow with this mod My OBXT build Link to comment Share on other sites More sharing options...
Underdog Posted July 13, 2016 Author Share Posted July 13, 2016 No point in the thinner jam nuts unless you also remove 2-3 threads from the ITR; otherwise the OTR will bottom out on the unmodified ITR. M14x1.5 is the universal Subaru tie rod thread size among all '05+ turbo models that I checked. LGT and Spec.B are the same 15:1 however the Spec.B actually has less total range (internal stops) to prevent the larger Spec.B tires from rubbing at full lock.

WRX USA Posted July 15, 2016 Share Posted July 15, 2016 LGT and Spec.B are the same 15:1 however the Spec.B actually has less total range (internal stops) to prevent the larger Spec.B tires from rubbing at full lock. Given the larger tires on the Outback it would seem that the SpecB rack would be the optimal rack versus an LGT one since you don't rub and don't have VDC issues.

rougeben83 Posted July 20, 2016 Share Posted July 20, 2016 do you have a spline count for the U joint connection on the 15 rack, or stock LGT U joint? I have an 05 STI steering rack, want to compare if it will bolt up to the U joint. Link to comment Share on other sites More sharing options...
oldskoolbiker Posted July 22, 2016 Share Posted July 22, 2016 So last weekend I took the car back to my home town which is deep in the Appalachian mountain, so there are a lot of really curvy roads. I did some spirited driving around my hometown and the VDC was kicking in quite a bit even with the traction control turned off. It was hitting the brakes right in the middle of turns. I called the dealer and told them the car is worse now than when I brought it in asking for the VDC to be re-calibrated. I'm going to call the dealer back on Monday and talk to the Tech to see what they say. At this point I'm thinking about doing this. I'm thinking about unplugging the steering angle sensor which should disable the VDC but also throw a check engine code. I then plan to use my Cobb AccessPort to delete the codes that get thrown by unplugging the sensor. Anyone have opinions on this approach? Link to comment Share on other sites More sharing options...

oldskoolbiker Posted July 24, 2016 Share Posted July 24, 2016 (edited) That might put you into a limp mode where full throttle is not available. Sent from my iPhone using Tapatalk Ok so I went and unplugged the steering angle sensor. Its a plug right at the back right side of the bottom of the steering column cover. After I unplugged the sensor, the traction control off light came on but everything else seems normal. No codes, sport / sport # seems normal. So I'll drive around like this for a bit and see what happens. Edited July 25, 2016 by oldskoolbiker Link to comment Share on other sites More sharing options...

oldskoolbiker Posted July 28, 2016 Share Posted July 28, 2016 Any updates regarding potential issues? Thanks No issues so far, but I haven't gotten a chance to drive the car hard enough for traction control or VDC to kick in. Link to comment Share on other sites More sharing options...

oldskoolbiker Posted August 2, 2016 Share Posted August 2, 2016 So far so good. I'm taking the car to Dominion Raceway in VA this Sunday for a true test. Will report back after the track day. Link to comment Share on other sites More sharing options...
WRX USA Posted August 2, 2016 Share Posted August 2, 2016 Please keep us posted, since this would be the only way for me to make the swap. Keep in mind that the difference between your stock rack and the STi rack is much smaller than the OBXT and the STi rack so even if he does have issues, you may not.

That's a valid point. I just want to make sure that should resetting the sensors not work, I can unplug it and avoid any VDC unwanted interventions.

tito_b0y Posted August 3, 2016 Share Posted August 3, 2016 So, I know this won't fit a 2.5i because of the different size/shape of the front crossmember. But will it fit a 3.0R Outback? 2006 SWP 3.0R 5EAT VDC BBQ 2008 OBP 2.5i 4EAT BBQ [RIP] Link to comment Share on other sites More sharing options...
oldskoolbiker Posted August 8, 2016 Share Posted August 8, 2016 (edited) Ok so I am happy to report after a full day at Dominion Raceway today that for sure unplugging the steering angle sensor completely disabled traction control and VDC. The only side affect is the traction control off light is on. Also for anyone wanting to know how good the STI rack is. Here is a raw video of one lap at Dominion Raceway today. This is a very tight track and having the STI rack here was awesome. Edited August 8, 2016 by oldskoolbiker Link to comment Share on other sites More sharing options...

I just want to make sure that should resetting the sensors not work, I can unplug it and avoid any VDC unwanted interventions. I want to report also that I drove on a dirt road where I was able to "drift" aka have some wheel slippage occur and some slight amount of sideways and I didn't feel the VDC kick in when I turned it off (just pressed it off) I also drove quickly over mountain passes with no steering issues (just fun). I had my dog in the back so I was focused on smooth though. Basically, I think anyone should do this. The VDC issues seem minor and defeatable.

rougeben83 Posted August 22, 2016 Share Posted August 22, 2016 so what's the final list of parts needed to make this work? No need to mix/match inner and outer tierods? I got an old 05 sti rack just sitting in my garage Link to comment Share on other sites More sharing options...
Underdog Posted August 22, 2016 Author Share Posted August 22, 2016 The 05 STI rack is not an upgrade. The only part needed is the 15+ STI rack, everything else is optional. The Crimson Dynamo Link to comment Share on other sites More sharing options...
LatentWagen Posted August 22, 2016 Share Posted August 22, 2016 (edited) The 05 STI rack is not an upgrade. That STi rack came in the Saabaru from the factory (as well as the 06-07 WRX), and is noticeably quicker than my LGT's steering. Might not be as tight as the '15+ STI unit, but it's definitely tighter than the Legacy. I drive them back to back almost daily. edit: did some digging and most sources say both racks are 15:1... however, they don't feel the same to me Edited August 22, 2016 by LatentWagen LW's spec.

Underdog Posted August 22, 2016 Author Share Posted August 22, 2016 (edited) LW - really not a fair comparison due to differences in the chassis. All else equal the car with the shorter wheelbase will feel snappier on turn-in due to the moment of inertia. Think of trying to spin a ball versus a dumbell. There are several other factors that could play into what you are experiencing. Wheel/tire specs would be a major consideration.

Underdog Posted August 22, 2016 Author Share Posted August 22, 2016 Wheel offset makes a difference as well (scrub radius). Also - it's possible the OTR attaches to the knuckle closer to the strut axis of rotation, which would have a quickening effect.

Rhitter Posted August 22, 2016 Share Posted August 22, 2016 (edited) so what's the final list of parts needed to make this work? No need to mix/match inner and outer tierods? I got an old 05 sti rack just sitting in my garage What is the track width of an 05? If its the same as 2008+ Nothing is needed, just bolt it up. For the 2015, nothing is really needed. I used thinner jam nuts and cut the tie rod ends to make sure there was plenty of adjust ability, none of that was really needed though. The 05 STI rack is not an upgrade. The only part needed is the 15+ STI rack, everything else is optional. It is however an upgrade to an Outback (but not a Legacy).
