boxkita Posted February 26, 2014 Share Posted February 26, 2014 did you remove the stock seatbelt? I'd keep it, as the multi-point system are not road-legal in WA. What did you do with the airbag sensor? Build my car Boxkita Track days Link to comment Share on other sites More sharing options...
boxkita Posted February 26, 2014 Share Posted February 26, 2014 there's a porsche owner that brings his track seat to the track and swaps it in/out for the day. You might check into http://www.plantedtechnology.com for their seat bracket. It might make it easier to swap in/out. They have brackets for all new century Subarus Build my car Boxkita Track days Link to comment Share on other sites More sharing options...

dustinsonger Posted February 26, 2014 Author Share Posted February 26, 2014 i understand but i have never hated a seat more than the stock obxt seat. i wanted this seat just as much for comfort as i did for track stuff. Link to comment Share on other sites More sharing options...

ClimberDHexMods Posted March 17, 2014 Share Posted March 17, 2014 I can't see clearly from the pictures, but your rear diffuser looks to be mounted in the wrong place, too far forward and not a steep enough angle. Maybe I did not see it correctly in the picture. At least it's long enough. But as it sits, most likely does nothing. Won't be too hard to correct though. I'm not aware of anyone who has actually ever measured the camber curve or dynamic toe change (bump steer) on a LGT or OBXT (but maybe someone has). So though some of us understand suspension geometry academically, I'm not aware of anyone who has actually checked to see what the range produces with stock mounting points. You can do it VERY roughly pass/fail style by checking whether your control arms ever become flat or even start drooping upwards when fully compressed within the range allowed by your specific coilovers and current height. You can check that VERY roughly with a floor jack under the opposite corner you're looking at, and a block of wood or two under the corner you're looking at just to see if anything jumps out as being way out of range. But if you're serious about time attack, you already know all of this and more, so sorry to waste your time. I like to see people build cars like these that might actually get pushed hard, so more power to you. Please keep updating even if some people are bored and take it out on you.

XenonK did 3-d mapping and measuring before creating his epic post on what wheels/tires fit. He may have done dynamic measuring as well, as he was very interested in extremely wide wheels/tires. I doubt he ever published any of that work. Build my car Boxkita Track days Link to comment Share on other sites More sharing options...
ClimberDHexMods Posted March 18, 2014 Share Posted March 18, 2014 XenonK did 3-d mapping and measuring before creating his epic post on what wheels/tires fit. He may have done dynamic measuring as well, as he was very interested in extremely wide wheels/tires. I doubt he ever published any of that work. That would be nice, but I doubt he did. Reason being he went to great length to document what wheels / offsets / tires fit and how, after finding out himself. Determining bump steer rate and camber curve requires its own set of measuring equipment (camber being a lot easier than toe, but both requiring a lot of work to do correctly), and to have someone like that then not share his findings would be odd. Ideally someone already did, but I have never seen anything quantified even by the racers. Realistically it's probably not anything drastic on the 4th Gens or one of the racers would have noticed by now. Even though coilovers usually reduce height, they also limit travel. Supposedly if you have kept your bump stops anywhere near stock travel, you're not going to have a problem. But I don't know, I've never measured [CENTER][B][I] Front Limited Slip Racing Differentials for the 5EAT now available for $1895 shipped, please inquire for details!

dustinsonger Posted March 22, 2014 Author Share Posted March 22, 2014 The rear diffuser is all wrong haha. Nothing about it is correct to be honest. The big thing with it was just getting under the car and making something, anything really so I could have a better idea of what I had to work with than just laying under there and staring at it all haha. And the camber was really a non issue. If you think about setting up a suspension for traction, you want more in turn camber to maintain traction on the outside tire right? So obviously the best option is to modify caster so just simply turning the wheel increases camber (well actualy decreases because we are looking at the outside tire that you want negative camber on but I digress) but changing caster in a specific manner to match exactly what your looking for requires engineering, fabrication and most importantly, money. Now how else can we get effective in turn camber levels while keeping somewhat desirable out of turn levels? Well as a suspension goes through its range of movement the camber increases more drastically as you reach its limits, so what we can do is design the front spring/dampener combo (coilovers in this case) to take advantage of this. By lowering the car taking into account not simply the cars height but the position of the hub in relation to its movement range we can find a good balance of camber for straight road performance. Then we can look at our left over possible spring travel taking into account spring binding, bump stop and wheel well/tire contact limit and take advantage of as much of that space as possible by choosing a spring rate and dampener valving that will allow the suspension to effectively give us the camber we want when we are mid turn. This is the secondary reason for my spring/dampener/height choice, the primary simply being the funds I have to work with haha.

dustinsonger Posted March 22, 2014 Author Share Posted March 22, 2014 Sorry I left out that the outback with its lower Mounting points didnt hurt this method of gaining in turn camber Link to comment Share on other sites More sharing options...
ClimberDHexMods Posted March 24, 2014 Share Posted March 24, 2014 ^^^^^ For a road car or for a DD autocross car, using lots of caster and little straight-line camber is fine. But for a time attach car, you're going to want it to sit on a more "race" amount of camber. Maybe you'll dial it in for time attack later... I forgot what stock spec is for camber, I think it's out to almost -1.0 front and almost -1.5 rear. You'll probably want more especially up front.

dustinsonger Posted March 25, 2014 Author Share Posted March 25, 2014 what im most likely going to shoot for is closer to around -2.5 to 3 in the front and 1 to 1.5 out back (haha get it, out back, outback hahaha i crack myself up. jk) Link to comment Share on other sites More sharing options...
boxkita Posted March 30, 2014 Share Posted March 30, 2014 you'll need custom plates to get that much camber. My BC Racing c/o plates topped at at -2.5. The rear can be done with the Whiteline kit. Be sure to do Johan's trick of moving the mounting point an inch back to recenter the rear wheel in the wheel opening. Vorschlag made/makes plates that have enough adjustability for the fronts. Stoplightassasin had a set for sale awhile back. Build my car Boxkita Track days Link to comment Share on other sites More sharing options...
