    Well, the rear suspension arms have eccentrics that allow you to adjust the camber of the rear wheels since the rear strut towers are not slotted. Given that the rear lower control arms are the same as the fronts, I suppose you could adapt the rear eccentric bolts and nuts to work up front as well. I haven't looked closely at the lower control arm mounts in the front and rear to be able to tell you what you have to do. I suspect it would not be a simple solution. I would be more concerned why your camber isn't coming into spec. What are your numbers exactly? Do you have any suspension modifications (lowering springs, etc)? It sounds like the car may be tweaked.

    For completeness, here is mine. I have only owned the car since 22,000 miles and didn't do an analysis on the first oil change. The latest sample had a lot of very hard use on it.

    Doesn't matter when you get the alignment (before or after the wheels). Wheels don't affect alignment. I will be shocked if those wheels fit. The fronts you may be OK, but the rears, a 315 is way wide to fit on a Boxster. GOod luck...

    The endlinks aren't the strongest and I suspect they are the source of the clunk up front. Everything else in the front end is pretty sturdy. The endlinks are pretty cheap and relatively easy to replace. I would check them first.

    Go with the Bilstein HDs. They are the same shock as OE (shhhhhh) but without the Porsche markup, they are much less expensive. Added bonus, the Bilsteins have a lifetime warranty. No-brainer.

    Glad I could help. Let us know if that was the problem. Loose plugs suck!

    Thanks very much for the tips, guys. This should be next weekend's project - once the parts come in from Sunset. I'll post some pictures and procedure if I discover anything beyond what you all have already mentioned. Thanks again!

    I did mine by feel and I think I covered the seal - just barely - I hope. There were 2 small shoulders on the top and the bottom of that portion of the AOS and I could not get these to be flush with the surface. I just put everything back together last night so it will be hard to get a good look at the seal, but I'll try and let you know if I can see the seal or leaks - nothing on the floor yet. Thanks for the input. I guess I did get my AOS installed all the way, but it's tough to tell and I was second guessing myself when I saw oil leaking. As it turns out my leak was caused by the oil filler pipe. It appears to be cracked at the interface just before it goes into the engine. It's causing a small oil leak (but even small ones make an unholy mess on the engine) down the passenger's side of the motor. Ordered a new tube today so hopefully once that's in it will be over.

    I have a question for you about this part of the AOS installation. I know exactly what you mean about getting the AOS seated - that lower-most connection to the crankcase was a major PITA for me. In fact, I'm not sure I even got it fully seated. I'm seeing a little bit of oil seepage from up there and I suspect I didn't get it seated enough. My bellows is sealed and not leaking. How much of that lower seal is visible with your new AOS installed? I'll try to take a pic of mine tonight to get your opinions. Thanks. John

    It is actually the heating of O2 sensor, not that it makes a huge difference. :P I just had that replaced yesterday. I had a intermittent CEL with same code. Tomorrow we have a little trip to Mammoth Lake, CA, with local PCA. It is gonna be a blast. :cheers: :drive: I had an intermittent P1119. Replaced both pre-cat O2 sensors (left and right cylinder banks) and it went away for a while, but it's back now. Anyone else have this issue?
  11. John V
    Thanks for the heads-up, brent, but my car has a new AOS. :(
  12. John V
    Late reply, but did you ever figure this out? To me it appears as though the oil is coming from up higher and dripping down from the lowest point, which is that hex nut / bolt. I have a similar oil leak, but I can't figure out where it's coming from. It's definitely working its way down the side of the engine and collecting on that hex bolt. Thanks for any insight... John V

    It sounds like your car is abnormally low. For a track car with no rules, you can easily solve the problem.

    john - do you have aftermarket toe links? i was aligning my car yesterday and am unable to run less than -2.2 deg camber in back and still meet my toe requirements. at -1.8 in back, i can't get less than 13/16 toe in (the left side is at max out). i do run RoW ride height, but i didn't think that would matter so much.... No aftermarket toe links. I have to remain stock (no RoW stuff either) for my autocross class. It surprises me that you can't get zero toe with that much negative camber. I cannot believe the RoW lowered you that much. The rear toes in as the suspension drops and obviously camber increases as the suspension drops, but that is a lot. I can't comment on the cause... sorry. This is an autocross only car, and low-speed handling behavior is important. If I run more rear toe or more rear negative camber, the car becomes pushy at low speeds, so I set it up to be a bit loose at high speeds. Probably if I were doing track work I would want more rear negative camber, and maybe some rear toe. Tire wear is pretty much nonexistent with my setup.
  15. John V
    I could probably get -2.0 if I wanted more negative. I want less negative camber in the back (or ... "most positive"). Increases in rear camber only make the car unpredictable at the limit, especially in transitions, and make the car more "pushy" in low-speed corners. I also do ProSolos in this car, and it maximizes the launch if the camber is minimum. I run 245/35/18 fronts and 285/30/18 rears so there is some understeer built-in as a result of that, but removing all the rear camber and toe makes the car very well balanced.
  16. John V
    The car is set up for minimum rear camber and zero rear toe. To acheive zero toe you set the toe adjusters to as low as they go and then dial in negative camber until the toe actually reaches zero. If you were to set the camber adjusters to "max positive" rear camber (about -1.0 to -1.2 degrees) and then set the toe you would not be able to get out all of the toe-in. Make sense? :) To string the car we set the strings to be parallel to one another, then measure how much the car is misaligned between the parallel strings and adjust the strings (equally on each side obviously) to compensate. That leaves you with parallel strings and a car which is parallel to them. HTH, John

    this is partially true for the toe eccentrics, but not the camber eccentrics on the lower control arms. i have a SmartCamber guage that i use to verify camber after this type of work. i've had the rear control arms removed four or five times. if i set the eccentric to its previous position, the camber doesn't change at all. I just verified that this is not true (at least for my car). I strung up the car last night to verify the toe prior to the ProSolo this weekend. The right rear was off because when I did the last suspension swap I removed the camber eccentric. Even though it was marked and put back to the same location, it caused the toe to be off. 5/32" in on the right rear. I should add that my toe eccentrics are set to as much toe-out as possible - so there is no more range of adjustment there - hence why I had to make the adjustment at the camber eccentric. I put the car on the slip plates and loosened the camber eccentric. I verified that there is about 1/16 of a turn of "slop" in the camber eccentric which makes sense - the camber eccentric is "captive" but it can still move laterally a bit once loose. Depending how the bolt is loaded (which is basically saying depending on which way it was last turned) you can get +/- changes in toe and camber. I tweaked it out and tightened it once the toe reached the right location. Camber change was minimal - I gained a slight bit of negative camber but really the goal was to get rid of the toe-in.

    Ditto. I think lots of people don't take the time to wetsand the color properly to eliminate any orange peel, and some don't even clearcoat the paint! In that case, yes, it looks very cheap. I spent the time to paint my trim properly, and applied seveal coats of clear which I then wetsanded and buffed to a high gloss. It makes a huge difference and looks worlds better than the stick-on stuff.

    that's definitely the way to do it. i've done several of these and never removed the axles. it's actually possible to split the ball joint and still remove the strut assembly with the axles and lower control arm in place. it's FAR easier, though, to remove the entire lower control arm and leave the ball joint in tact. three hours must be some kind of record! the best i can do is four, but that's just one man. Yeah, after doing it this way I can't imagine why anyone would remove the axles, calipers, etc. I did the front without cracking the ball joints or control arm or caliper as well - but it's kind of a wash as to whether that method is easier or not.
  20. John V
    A buddy and I just did another M030 install. Three hours start to finish, both ends of the car. I found that the biggest pain in the a$$ in this job is removing and reinstalling the rear axle. So this time, we didn't do it. We found it to be much quicker and easier to do the rear by disconnecting the rear camber eccentric bolt. If you do this, you don't need to remove the lower ball joint, you don't have to pry the control arm, you don't have to remove the axle and you don't have to remove the brake calipers. Attached is a pic showing what I mean. I'm sure some of you knew this but nobody ever attached a picture.
  21. John V
    Unfortunately because those eccentrics have so much slop in them, this in no way guarantees that you're at the same alignment as when you started. If you've ever aligned one of these cars you know that if you turn the eccentric, often no change in alignment will occur for the first 1/16 of a turn! You may be fine - but I'd suggest getting an alignment. Quick question - did you still have to disconnect the axle doing it your way (removing the eccentric bolt)?

    Go buy yourself a snap-ring pliers. You'll need them sometime if you keep working on cars, and they're cheaper than the Porsche tool. Alternatively, you can use an allen key to remove the tubes. Find an allen key whose small end will snugly wedge into the tube, and use a locking pliers to pull out the tube. Either method works very easily. And cheaply. Thanks for the idea's. I willl try the allen key. Keep fingers crossed i don't break the tubes. If you break the tubes, no big deal. You're replacing them, remember?

    Why do you want to add another step to starting your car? Doesn't make any sense to me. You still have to put the key in and turn it - why add a button press to the process? :rolleyes:
  25. John V
    Yes. Unfortunately, not much you can do about it. The side-to-side pivot mechanism uses plastic for the pivot joints. It wears out. A friend and I are working on a solution to repair the older, worn-out shifters, as well as tighten the action on newer cars. Stay tuned.
