Saw a similar post over on Zilvia so I wanted to ask. What is YOUR suspension setup? Front and Rear (Toe in/toe out, camber +/-, sway bars) chassis reinforcement? Front/Rear tire pressures. When you made a change/addition what effects did you notice if any at all. I also came across this link for setting up you car to promote/demote oversteer. http://www.autornd.com/Merchant2/mer...SUSPENSIONTUNE

I would think one would want to promote as much oversteer as possible when on the track but someone mentioned that its not necessarily true because when you begin to slide it becomes more difficult to keep from spinning out. Those who know what are your thoughts?

i don't want to tell you cause then you'll duplicate my setup and then I won't be cool anymore and therefore I will put a dumb sarcastic comment instead that way the coolness of mine stays chillin........................................... .................

J/K That is the reply I usually get when I ask that question .......

I'd like to know also to learn the tricks of the trade too !!!

 

Well what works for one person may/may not work for another. Like those with lots of power may like the understeer so that when the car comes around under power its easier to control or vice versa. Cause after my engine gets put in Im gonna be slowly buying tunable suspension parts to play around with.

 

I'll tell you all what I run...

Up front: KYB Buzz Spec struts, GC coilovers (450lbs/in), SPL tension rods, Tein inner/outer tie rods, Tein Camber plates, ebay strut tower bar, Suspension Technique sway bar, Nismo Power brace, and whiteline LCA bushings. My struts are set at full stiff on drift days. My camber is set to full negative (roughly -2.7 degrees), my toe is 0, and my caster...hmph, I forgot. Currently I'm running AVS ES100's 215/45/17 mounted on 17x8" 5zigen FN01RC's at 36psi (cold).



Out back: KYB Buzz Spec struts, GC coilovers (350lbs/in), SPL RUCAs, SPL Traction rods, Hicas lock bar, SPL aluminum subframe spacers, Suspension Technique sway bar, ebay strut tower bar, whiteline RLCA bushings, and a S15 HLSD. On drift days the rear struts are set 1/2-way. I take whatever I can get in tires, but at the last DDay I was running 215/45/17" Falken ST115's on my 17x8" G35 wheels w/ around 38psi (cold). Alignment in the rear is -1.25 degrees of camber, as close to a 0 toe as I could get (I think it's about a .15 degree or less toe in).



I'm always trying new things with different results though...I'd say just experiment and figure out what you like best. And no, my car is not an oversteer machine...I try to make it handle as neutral as possible.

 

just go with what you like and try lots of set ups, at DDay i was running my rear tires at 1/2" toe out, and i had my Megan Coilovers set camber=2 degrees negative up front and -1.20-25 dont know yet on rear. Dampening was at 10 on front and 12 on rear, the car felt like it had a constant war against understeer, it actually felt like it was in love with oversteer hence why i spinned out so much, even Tony schulz commented of how easy my car was drifting. later on this week when i go practice i am going to try to set my dampening a bit lower (stiffer) and toe in the front just by a bit.

 

Here's my current setup:
Front Camber: -2
Front toe: 0
Front Caster: +7

Rear Camber: -1
Rear toe: 0

Suspension upgrades=
BAttle Version TC Rods
Battle Version RUCA's
GAB Coilovers
That's it.

Also, I ran bald tires in the morning, and it sucked. I had new tires mounted during lunch....much better. Tony Shultz drove the car with teh new tires and commented on 'how this car was one of a few that actually scare him'. For him, the car rotates way too easy. Oh well.

anyone just ever go out one day and mess with suspension settings? Like go around this corner at this speed with this setting then mimic the same conditions with different settings?

 

Thats what i am plannign to do this upcoming weekend, at DDay the setting i was running induced too much oversteer, now i want to look for a balance between understeer and oversteer. so I am going to go practice and mess around with my suspension to see what do i get out of it.

 

Suspension Upgrades:
Front: Tein HE Coilovers (8k springs), SPL Tension Rods, Tein Inner/Outer Tie Rods, Cusco STB, Jspec.com Front Ladder Bar

Rear:
Tein HE Coilovers (6k springs), SPL Pro RUCA's, SPL Bumplink, SPL Toe Rods, Cusco Rear STB w/ Triangle Brace, Jspec.com Rear Ladder Bar

Tires:
Front = Kumho Ecsta 712's (40psi cold daily driving, 35psi cold drift days). 40psi gives MUCH more of a tighter feel driving, I love it for those curvy roads. Can really feel a difference between 35psi and 40psi up front. Although 35psi gives tons less understeer. My old set were Yoko ES100's and I loved them. Less of a difference between the tire pressures though.

Rear = Kumho Ecsta 711's (40psi cold daily driving + drift days). I love these tires w/ the KA. Break loose easy and very predictable, although if I had more power or higher entry speeds turns I'd want something that grips better. Never had them chunk on me yet and good wear even pass the wear bar until you hit the belts.

CURRENT SETUP -
Front:
Caster = +7.5
Camber = =2.5
Toe = 0
Wheels = 15x7" +0 (205/50 tires)

Rear:
Camber = -2.75 (wheel/tire fitment issues)
Toe = 0
Wheels = 15x7.5" -5 (205/50 tires)

OLD SETUP -
Front:
Caster = +8
Camber = -2
Toe = 0
Wheels = 15x7" +0 (205/50 tires)

Rear:
Camber = -1.5
Toe = 0
Wheels = 15x7" +0 (205/50 tires)

 

As in dampening settings?

Yeah.

Alignment settings?

No. I do too much daily/highway driving to be getting alignments every few weeks.
