I would check the wheel play since that reminds me of the way my car was doing with a worn hub. If you do have a wheel play, I would carefully find out where it is coming from and go from there.If there is no play to be found, go with what JT wrote up there.Also, have in mind that some...

Well, what he is afraid of is our ability to use 1G engine in that car and gain 50 HP on the top of what is there right now. There would be a loss of the bottom end compared to the T25, but probably not as much to hugely upset the National type courses. Then, the next thing is the fact that we...

Well, if we just knew after the day one that turbo was gone we would probably steal one from Sam's car (DS only DSM), but we didn't. The very first sign of the trouble was up in the grid half an hour or so before the start when it was already too late.As of the 245s vs. 285s I strongly...

Well, after all this mess here is the overview of what happened at the 2006 SCCA Solo2 Nationals for the Smokey Team!! Charles and I left for Kansas around 7 pm on Friday in order to get there before they would close the gate at the HPT site and ready for the Test & Tune on Sunday morning as...

I had similar thing happen to me a while back on the ACT 2600. One of the springs fall off and got stuck between the flywheel and the disk so I couldn't disengage the clutch any more. Starting it in the gear and rev matching got me home and then later all the way to the place where we took it...

Well, you could get an used set from someone...But, you have to get shocks no mater what. If you get shorter springs with the same rates, your car will be bottoming out every chance it gets. If you get a stiffer shorter springs than you need stronger shocks to control them.Fedja

Well if you have asked your self why would car bounce in the first place, you wouldn't blame just your springs for it. The shocks/struts are those who control how fast your suspension is going to move under the differnet loads.Now you ask your self what do you want to do with your car. If...

You don't have to spend $700 for the Koni shoks. You should find them for around $550. Just a quick search on the web showed me these at Shox.com for $571, so with some shoping you can get those which would be my recomendation as well!!Good luckFedja ps. well the link doesn't really...

There is really no front upper control arm on the 1Gs...Fedja

Hmm, my car does the same thing but only when turning to the left. It is doing so for the last year or two I would say. Brand new bearing on the passenger front didn’t make any difference at all. That axle is also pretty new as well. Checked the shields and they seemed fine as well. It does...

What is the AC compressor for? :)Fedja

Well, that was the only conclusion that made sense to me. If someone has another way of explaining this phenomenon, I am all ears. And I am sorry about your car not being unique... :)Fedja

My car does the same thing when hard turning to the right (noise comes from the driver side rear tire). In my case it is due to the tire hitting the fender while experiencing heavier weight transfer. Check your tire for any marks from the fender on it. For some reason suspension geometry on that...

Well, considering this is a FWD we are talking about, I would use slightly different settings instead. Main issue with the FWD is to make your rear end to play well. Since there is no driving there you have to use your feet (meaning brake and gas). What helps in that case is toe out in the rear...

Here is a good place to start - Penske Manual. You will find a lot of info on how to adjust different types of adjustments. How much will this be related to the AGXs is questionable, since adjustablility of those is on the lower side...Good luck!Fedja

Hehehe, the problem is not the pump, but you. You are the one trying to turn too fast to start with...Fedja

The best and cheapest fix is to learn to move your steering wheel slower without any jerky attempts. In most cases, even if your wheels would move as fast as you want them to go, it would just cause your traction in the front to go away!! If you learn it the correct way, you will be much safer...

Yes, you are right about this, but (isn’t there always a “but” :)) you are still trying to fix one problem by fixing something else. Usually that has a price to pay and in this case you would have your car tighter than you would like it to be (except if you are core drag racer of course). By...

Sorry my bad there seeing it as an inside rear! But, what I wrote still applies between the center diff and the side of the car that is spinning. That is the job of the diff that is on that side of the car, so in your case your front diff. If you would have a better diff in there (only Quaife...

I wonder how you came to all of these conclusions. For the first part, I raced my car with all stock diffs in SM with power above 350 HP and never had any problems with center diff (or the front one as well).As of the second part, you are very wrong there!! Center diff has nothing to do with...

I din't say that your ABS unit is bad. If you overuse your brakes, you will have pumping from the ABS hydraulic pump which you can feel in your foot. That is why I said that would be easy to spot and that would be normal operation for your ABS unit. It is just trying to tell you that you are...

The one of the things that I could think of is you ABS system, but that would be easy to spot. Then, if your rotors are warped a lot, they will cause some oscillations when braking, so that could be another reason for the pulsing. The last thing that I could come up with is that your caliper(s)...

Well, Guy Ankeny built a set for my car for $1,600 a piece. Originally his price was $1,250 per corner, but due to some extra work, plus addition of the top pillow mounts the price went up. Add an IRS or Hypercoil spring to it for $50 - $60, shipping charges, and that should be all you have to...

Hmm, you obviously never had an experience with the double or especially the triple adjustable shocks! Otherwise you would not make such a comment! Benefits of triples (especially for autoX) are uncontestable! Topeka is known for its bumpy surface and usually people have issues with that here...

It would help a lot to see things better if you would tell us what where the speeds at each of the turn phase, and cornering Gs during such a different driving stylesFedja Ps. Yes, that was the first time for me to drive a car with the Quaife front diff

Last time even 20 tones hydraulic press couldn't budge on those, so don't hold your hopes too high. Since your car is 96, the axle and hub probably have quite a tight grip that you might not be able to break apart without some serious damage to the axle portion.You could loose the wheel side...

Well, this is a subject heavily discussed all over the different forums and I am sure that you will find a lot of versions for answers. Basically things come down to two cases. One is that Quaife will help put more power down during the exit phase of the corner. The other one is that it will...

For right now, I would keep the stock unit with the VC and the 4 spider conversion at the Speed Design. Unless you can fit that ACD unit from the EVO... :)Fedja

POS or NEG are just agreements or something that wheel alignment machine manufacturer decide to use on their stuff. Usually, POS is toe out and NEG is toe in.To be safer with these terms, toe in points your tires to the center of the car - kind of like turning in. So, for the front right...

Going more negative in the rear (camber wise) will give you more toe in.As of the things that mechanic said, I would check with another mechanic before jumoing to any conclusions.Difference in the front camber is minimal, and it will be even more even once you sit behind the steering...

I just can’t believe that you are so stuck with the wording that you use and can’t see anything else in here :confused: It is more then obvious that solid connection that you get with fully-locked diff sends power equally everywhere (read both ends). You in the way get 100% of power that you...

Hmm, I read all of the stuff that was said up there, and somehow I missed where did Dennis say things that you claim up there?? This looks like that you took some of the stuff out of what he said and converted it into something else, but still managed to blame Dennis for it. You definitely...

Actually, you are wrong here!! With 100% locking power goes equally to the both ends all the time. The torque on the zero grip side is zero. 100% of what is possible is on the other side, which is much less from the 100% of the torque that engine is producing at the time! If 100% power would go...

I do understand what are you trying to say here and I gave you already that you are correct with the stuff above. What you don’t get is the effect that diff has to the handling of the AWD DSM (or EVO due to similarities), which is what we are discussing here!And since we are on the handling...

Hmm, I read somewhere that if you think it is impossible, it is possible that you are not thinking! :)Actually the fact that OEM VC takes a bit time to get into more locking as a great thing!!Now I understand where your errors are coming from! You think that center diff needs to start...

It comes very interesting that you see a need to explain to me (not to Toby) how those diffs are working. I gave you a comments on the stuff that you wrote earlier and wherever I though that you where off, I pointed that out. Where I agreed with you, I simply skipped in my reply. But, what I get...

Here is the second part of the essay! :)I think that I already went over this part and still waiting for the answer :)Yes, you would get more understeer if you have a mechanical diff of any kind (even Quaife). The problem for them is that they can only fix one of the problems, which are...

Not quite getting this either…more info needed to understand this “past” thing!Actually, you are the one that is assuming things that I didn’t say. And the things that I did say, you somehow omitted in your reply.I didn’t say anything about where it will go. But I did say that it can go...

Are you sure about this? As far as I know, fully locked STi has some noises when turning and I believe that comes from the 35/65 lock. Unless it never goes to the full lock mode, I think it is rather that and not 50:50.From what I know so far about the ACD, it acts just like an open diff...

I have only a link of type "how it works?" for the AYCSorry...Fedja

Good find!! :)Fedja

It is 50:50 at full lock!Fedja

EVO has a clutch type controlled with hydraulics…pressure variation changes the locking amount from fully locked at 50:50 on one end and all the way to fully opened on the other...Fedja

I don’t know why you using excessive oversteer as a defense for the understeer. They are both tuning problems and need to be corrected. And, it is much easier to correct understeer then oversteer.Hmm, it is natural tendency for any car to oversteer when braking and turning. There is hardly...

This is another of the common misconceptions about the better suspension or better car per say. If you have two cars, one stock (let say DS) and other one nicely modified (fits in the ESP or SM). Better suspension on the car two will usually give you better times on the typical autoX course. You...

No, it is never good to understeer. Period! If your car understeers, that will mean just longer time for it to get into the position where it needs to be. Also, if you need your car to understeer to get into the correct position, that implies that you already made a mistake and turned your...

This is just partially correct. The car will react quicker for sure, but that is not necessarily a better feedback at the same time. A beginner/intermediate driver might get all of that information too quickly and respond abruptly to them. It would very well make the car faster then the driver...

Another interesting thing that affects understeer/oversteer on our cars is our driving style. Some people are more smooth then the others. Others like to unset the car and force oversteer, which they use to go through the turn.The point is that car will behave differently if brought to the...

I just didn’t have handy original 2G ratios, but I know that some of the gears are above 1.000, while the others are below. So, for less complicated calculation I used an easy number. This I believe goes somewhere between the 3rd and 4th gear.Actual speed that was calculated at 3000 RPMs and...

So, one end is 3.8 while the other is 3.807!If you would shift into the gear that has 1.000 ratio and spin the car at 3000 RPMs and using 25.3" OID for wheels (EVO wheels but, should serve the purpose here as well), that would give you a speed difference of 0.109 mph. That comes to 0.18% of...
