Any one used all Che's suspension pcs?

[JP-s-in st. louis]

WOW No one and not even a word from the sponsor?

Maybe I will not use these pcs. and just go GT3 control arms and Agency Power parts.

I have the upper track arms, both front and rear and i have to say, that i find it impossible to believe that anyone would be able to notice the car being "Less nimble" with only about 7-12 more lbs. of weight added on the car.

Again i have them on the front and rear of my car and they eliminated the rattling sound and i havent noticed any other new noises as a result of using the track arms.


If you really notice a difference in handling charactoristics, i would check your alignment again.

CJ, yes I did notice a slight difference in the handling characteristics of the car, feeling slightly less nimble. And no, I don't presume it to be from the addition of the 7-12 more lbs of weight added to the car itself, as you say... I could add that with some groceries in my trunk and definitely not notice anything. What I was concerned was about adding that much weight to the suspension itself, which is of course constantly moving.

So, like I said, I don't know if the culprit is the heavier arms adding weight onto the moving suspension, or if the culprit is the need to realign the car, due to the change in suspension, as I don't doubt that my toe, and perhaps even caster are slightly off now. I would try to solve the mystery by getting my alignment done right now, but I have a few more things I plan to do to the suspension and will wait after all the changes to get the alignment.

Does anyone know, from theory or first hand experience, whether adding weight to the suspension with these heavier arms, would cause a slightly slower response and adverse handling characteristics? Perhaps Insite can chime in...

Here you go

http://en.wikipedia.org/wiki/Unsprung_weight

Basically, the momentum involved with movement of the suspension parts in reaction to road features can work against the desired motion of the suspension, therefore, less mass, less undesired motion. Can you feel an increase in unsprung weight? It depends on the degree of increase. Does it matter? Absolutely. The tradeoff being that lighter parts are typically less resistant to bending or damage, this is definitely the case when comparing steel parts to aluminum ones.

Just to add my .02 I have the Tarrret adjustable rear toe arms. The toe arms seemed lighter than OEM parts. Once I added these I was able to get my lowered suspension into OEM specs. Prior to getting the adjustable toe arms I as changing my rear tires every 5k miles. I have 8k on my rears now and they seem to have plenty of tread left.

I wasn't aware of this suspension mod. Would it be pointless to add this if your car is still sports all stock suspension parts?

Which mod are you referring to? We were discussing a few different arms on this thread so far... control arms, track arms/trailing arms, tension rods, toe arms, etc...

Hey JP-s, the GT3 control arms and agency power parts would be replacing different arms/parts than the arms that Che offers. The "track arm" as everyone here refers to, are the rear trailing arms. The Agency power "dog bone" arms, as far as I know, are for the 996/997, and won't fit the 986, despite what the website says. Correct me if I'm wrong on that, but the rear suspension on the 986 and 996 are different, and I just do not see how one could use the dog bones on a 986.

hahaha, a bit of both! Anyone feel free to add to this, as I don't doubt I'm missing a few, though here is what I see as available options as upgrades for the 986 in terms of suspension arms:

- Lower control arms (front & rear) --> GT3 & GT3 CUP lower control arms
- Adjustable rear Toe arms --> Che aka HardRace, TRG, Tarett, & GMG WC toe arms
- Rear Trailing arm, aka Track arm --> Che/HardRace
- Front "Tension Rod" arm --> Che/HardRace

[Cloudsurfer]

Well, got done with my install today, which involved Che's rear toe arms. These did allow us to get an absolutely perfect alignment, however, required some modifications to work which I'm not pleased about. The rod ends on these things are HUGE, and we had to remove some shims from the rod end, and trim the backing plates to get them to fit. Even still, there is barely enough clearance for my 18" BBS RSIIs. There is no way you could fit a 17" wheel now. All told, the added PITA factor for this cost me an extra $100 in labor on my suspension work.

All in all, I could be a bit more pleased with things.

Patrick, do you have any pictures, or would you be able to snap some pictures of the modifications you had to do to the trimmed backing plates, and the removed shims? I am not sure exactly which parts you had to modify.

Also, have you noticed any better/worse feel in drive quality, or handling response?

^^^You know add in the GT3 front sway and drop links and that sounds like a nice set up there. Maybe the coilovers will have to go on the back burner for a month, so I can get all these parts to go on at the same time. I would hate to pay for 2 alignments and corner balance. The finance' now has me on a mod budget...

Oh well that is why we still pay for her undergrad in accounting I guess. How do you all feel about the front adjustable lower control arms? I was planning on just doing the rear.

[RandallNeighbour]

semi-related question here...

I've got to replace my rear lower control arms as well as the track rod OR the Track control arm (whichever one makes the car go "clunk" when driving over a bump) and I'm thinking of putting in a set of Ksport coilovers while I'm at it.

If I use the Ksports to lower the car, will I have alignment problems in the rear or front or both?
