Fixing corner grip on bumpy surfaces?

ChrisSlicks

Sway bars did wonders on the bumps for me. Allows much less bound and so the re-bound doesn't kick the rear out.

I've heard those are easy to install as well. Did it change the balance of the car much, or mostly just help with body-roll?


Also, which sway bars did you go with?

ChrisSlicks

I went with the Hotchkis, which are perhaps a little too aggressive for street use. The Stillen is probably a better street setup.

The sway bars detrimentally affected low speed aggressive turn in until I increased front camber (using the SPC camber arms). I think this was because there was less roll induced camber. For higher speed cornering it improved the car wonderfully.

Kann, you ride, don't you?

One of the nice surprises when I upgraded my K1200RS with F&R Ohlins was how it handled bumpy surfaces. I was expecting it to be more firm, but the compliance of the Ohlins was a revelation. There is an Ohlins suspension for the 370Z...but it costs between $4254 and $5059 yowza might not be within your budget.

Completely agree on ride height, no way would I lower this thing on the street with the roads the way they are around here.

I think part of it has been getting used to the Z. I don't notice the issue as much now...

I'll probably go with KW Variant3's and their lift deally, so I can handle steeper driveways and such....

I have this same problem and it is NOT normal. I feel that it is unacceptable for a car to behave like this. The car handles great in all other aspects, but this is downright unsafe. I've also driven many different cars with various suspension setups and I have never experienced this until I got the Z.

I have to agree to some extent. I am hoping the KWs will fix the problem when I can afford them. The effect for me is that the car feels much heavier than it is when canyoning.

i know what the OP is talking about first hand. my BC coilsovers can be set hard enough where it skids over the bumps..... great for a smooth track/street, but terrible otherwise. i keep it in the middle.....

sway bars made the confidence skyrocket. no more unsettled rear end, or body roll.

i do need the camber i think now.....with the hotchkis. at 90% they are great. but when i push the car hard, it slightly understeers on turn in, which quickly goes into snap oversteer if im not careful (rear sway on full stiff, which is too much, but helps the understeer on turn in).

i need to order the arms, but dont have the $$ right now.

all in all, id still say the oem set up is a GREAT compromise of the above.

Would the SPL rear traction arms help?
