So I am lowering my car on the eibachs and plan on sticking with the stock 19s for now,

To improve handling for those who know or have them,

do both sway bars work best?

On my buddies TSX FWD he just used a rear as the front actually took away cornering, so he didnt get both just rear.

I want to know if the g37 needs both, or can do with one just fine/better.

Appreciate the feedback, thanks guys!

Hmm, I have never just done the front as they come as a set. I have Stillen sways and they improved the handling all the way around.

 

^same here. I got both and am glad i did.

 

i have both stillens ways and i love em and im also on eibach pro...got rid of my tein s techs..

 

From Wikipedia:

"Anti-roll bars provide two main functions:

The first function is the reduction of body lean. The reduction of body lean is dependent on the total roll stiffness of the vehicle. Increasing the total roll stiffness of a vehicle does not change the steady state total load (weight) transfer from the inside wheels to the outside wheels, it only reduces body lean. The total lateral load transfer is determined by the CG height and track width.

The other function of anti roll bars is to tune the high g-force / limit understeer behavior of the vehicle. The limit understeer behavior is tuned by changing the proportion of the total roll stiffness that comes from the front and rear axles. Increasing the proportion of roll stiffness at the front will increase the proportion of the total weight transfer that the front axle reacts and decrease the proportion that the rear axle reacts. This will cause the outer front wheel to run at a higher slip angle, and the outer rear wheel to run at a lower slip angle, which is an understeer effect. Increasing the proportion of roll stiffness at the rear axle will have the opposite effect and decrease understeer."

Normally RWD cars tend to over-steer, thus needing to beef up the front sway. However, I think the G37C tend to under-steer, so beefing up the rear-sway would give it a more neutral feel. Just my 2cents. Feel free to chime me or correct me if I'm wrong.

 

^^ I think I will get the set both front and rear then.

For those who have it How much faster could u take turns at?

My friends TSX gained like 15mph in turns on the freeway.....

 

I try not to overdo it, but there's a particular turn that i feel more comfortable taking an extra 10MPH with. It depends on what i have the coilovers set at.

the biggest setback for me, though, is that my tires aren't nearly as grippy as the Bridgestones. if i had RE050's, i'd probably be taking that turn even faster.

 

u can def go in 2 different type of turns 10-20mph faster...but that can also jsut be in peoples heads including my own..lol..but it really does feel awesome, you will have the same set up i have besides my big rim n tire set up...

try getting some awesome tires...the stockers are good, but some wider stickier tires are always a plus im useing vredesteins sessanta tires 245-30-20 and 285-25-20 on my wheels...i like the stiffness and the harsher ride..lets me know im in a sports car...

 

those tires are stickier than stock?? whats thread wear at 280??? stocks are 140 really sticky at245/40/19and 275/35/19...stocks were better than the nitto invos i have now at 255/35/19 and 285/30/19...........I have JIC Magic coils with stock sways...no body roll

 

^im going stock 19s, and lowering it about 1 inch,

will aftermarket sways help?

i feel like the stock 19s dont gimme any real grip on turns

 

try this....put your stock rear tires on the front,buy new rears 275/35/19 same stock brand...try that till you lower your G....once you lower it some body roll will be eliminated but still there.....depends how hard you drive....i was happy....till I got coil overs....now she rails...but tire grip is a prob.........it will be cheaper to get sways and they do help......sorry babbling lol jus thought i toss you some other ideas

 

I think im going to lower the car an inch, and possibly just add front and rear sways, im an everyday driver but sometimes i like to speed thru corners, espcially in the bay area with a million freeways. I do appreciate all the feedback...
