I would appreciate Vendor feedbacks and anyone who has an idea or suggestions.
I had the GMG adjustable sway bars, they were removed as the front one may have been bent, I placed AP ones, not bad but I would like a stiffer adjustable sway bar. Any suggestions are appreciated.

 

dont wanna go too stiff on the front to get rid of understeer.

 

I just want to stiffen the rear a bit more. the front is doing fine.

 

set your rear sways to 'stiff'. If not enough, then change out the rear droplinks to some stiffer ones.

 

So by doing this i will get a stiffer setup? What about the rear strut brace? i have one that goes for the front, took it off as it did not fit well and was pushing on the small clutch fluid reservoir. Thanks for your input. who has a good rear drop link? and would it affect my corner balance?

try tarett or RSS for rear drop links. it would definitely be stiffer vs stock. Set to soft front and stiff rear.

Thank you.

 

If you really want stiff rear sways, try these:

 

RSS ones look pretty interesting. I will get with alex... Thanks

 

The supercup sway bars are supposed to be pretty stiff. I like the GT2 bar myself. Give Porsche motorsports a call.

 

Hello KA many good points you are asking. I am glad, and thanks to Sharkwerks, the drop link has finally got the attention it deserves. As Neil has mentioned, most definitely an after market drop link will make the sway bar feels stiffer. By replacing the compliant rubber joint with an all metallic heim joint, the drop link will
a. Increase the effect of the sway bar
b. Increase the effect of any change you make to the sway bar settings

When I was doing my "web research" way back when, I could not find any report on the effect of drop link alone (without any other parameter change). So far, I've switched in/out twice. This is what I have found (emphasis: personal preference/opinion):

Pro's:
As expected, the car does lean less (change from my initial impression)
Makes the car feel less rubbery and bouncy
Makes car feel stiffer and more planted

Con's:
Increase road noise
Increase engine noise to cabin (weird, but true)
When you hit bumps, the car will make a solid noise and in general feel harsher on street driving.

For lack of better description, it's almost as if you are increasing the damping factor of the coil-over. I would run my tires a little lower (1 psi) with the solid drop link than without.
A couple of us in fact have found that with rear drop link set to full stiff on an after market sway (mine is GMG, the other person's is GT3's), the car is almost intolerable hard for street driving. I would be interested in others' impression on this.

Considering what it does, it is not a surprise that this drop link is used more often by people on GT3 forum (rennlist). IMHO, if you are taking this car to the track, it's a no brainer. For street driving, it's a matter of personal preference. I switch it in and out every 6 mos or so because although the drop link makes the car feel harsh, there is a very nice planted and aggressive sensation to the car with it. Cost of switching = $100, very cheap.

BTW, I believe the very first post I saw of drop link is by ERP (anyone corrects me as needed). I use Tarett as it's been around a very very long time and used by people on rennlist GT3 forum. RSS should be fine also.

 

I should add that although us amateurs use anti-sway bar to, of course, reduce sway, the pros would use sway bar to influence its handling. Ask any pro and they will immediately link sway bar to understeer/oversteer characteristic.

To make car oversteer: the setting is full soft front, full stiff rear.
To make car understeer: the other way around, increase front stiffness, reduce rear stiffness.

Because the 4WD Turbo has a tendency to understeer/neutral steer, whereas at the track pro's like a little oversteer, the usual recommendation for the Turbo then is: Full soft front, full stiff rear.

I have never used that particular setting above, because as mentioned, full stiff rear makes car intolerably hard on street driving, and full soft front makes the steering less tight than I would like. But I am an amateur, so please take opnion with a huge grain of salt.

 

I have RSS sways with TRG drop links. Front is set at neutral and the rear at stiff. The car handles great. The ride is a bit harsh, but it really did dial out the understeer and the car feels very neutral now. Talk to Alex about some RSS sways. They do work very well.

 

Re. corner balance, a purist would argue that corner balance should be done only with adjustable drop link.
I have no direct experience but have read that the steps are:
1. Disconnect drop link
2. Corner balance
3. Connect drop link. The adjustable drop link allows this last step to be done without creating pre load on the suspension.

It's a little too complicated for me to explain why here but next time your car is up on the rack, tell the tuner to explain to you why you could create pre load on the sway without adjustable link.
