Any one used all Che's suspension pcs?

[JP-s-in st. louis]

If you have please discuss the pro and cons of these. I am going to purchase the KW V3 coilovers next week. While at it I am really thinking that for a bit more, and add all 3 of pcs. This of course will be in addition to corner balancing.

TIA

Josh, I have the rear track arms (rear trailing arms), and they are really really heavy compared to the stock arms. After installing them, yes they got rid of the noise I had from the worn stock bushings/bearings, though there are some quirks that came with them. Sometimes while going over a dip/slose quickly with some decent speed, it sounds like they make a scraping noise... could be the sound of the pillowball/spherical bearings moving/and the arm slightly turning on the pivoting end, though not sure what the culprit really is.

Also, I am really wondering about the weight issue. So many times I'll read about car manufacturers highlighting their aluminum suspension... I assume to highlight the lightweight factor of the suspension... Seeing as these arms weigh so much more... by hand feel, they feel like about 3x the weight of the stock arms.

My car felt slightly Less nimble after the addition of the arms... I'm wondering though, since these are trailing arms, which I thought were meant mostly to control anti-squat, that they wouldn't affect cornering response... So I'm wondering if the less nimble feel is either 1) all in my head 2) due to the heavier weight, or 3) due to the fact that I have not yet realigned the car since, and I'm sure the alignment is slightly off now.

I am debating the addition of the front arms, and the rear toe arms, because of this weight issue. I worry that the addition of these other arms, would add more weight to the suspension, and make the car less nimble and less responsive. I noticed the other aftermarket toe arms, like TRG and Tarrett's look to be lightweight aluminum, and use half of a factory oem aluminum rod. Comparing these options versus Che's toe arms is what I'm interested in. They weigh much more and are made of Steel, not aluminum.

I'm definitely no suspension expert, so I would love to hear everyone's theories and input on this.

Claude- That is a very interesting observation. I am installing Che's rear toe arms this week, to correct for camber/toe when lowered, and will let you know how things work for me.

Its true, car manufacturers are touting aluminum components in the suspension heavily these days, and there are improvements to be had by lowering unsprung weight.

Sounds good Patrick, please update us on before/after feel, and any other notes and thoughts you have regarding the install, fit, feel, quirks, etc.

Thanks!

Not as much as Rotating Unsprung weight... (wheels) but it does help...

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.

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.
