Fixing corner grip on bumpy surfaces?

RCZ

Hmm... first off, When you are ready...I can get you a pretty good price on the KW's.

Second..you may not really need to go so crazy as getting coilovers, check out some of the available options for lowering springs. Otherwise, they arent complicated to play around with. They give you parameters to stay between, however if I were you I would just use the settings they put on the V3's from the factory, they are perfect.

Don't forget also that you will NEED camber adjustable control arms so you can add another bunch of money to your estimate.

As far as how hard everything is to install... Its pretty straight forward, but if you do it in your garage it will take you a good amount of time...specially if you are doing the control arms too.

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.

Thanks, I'll keep that in mind on KW's - it'll probably be around tax-return season

Also, I'm not really after lowering - so would camber arms still be needed? Granted, I know they'll allow for more adjustability, but, will it be nessicary?

Good to know on factory settings being right

Installation is the only concern of mine - I mean, if you jack the car all the way up, is it a matter of popping them off where they're not under a lot of pressure, or, is it something where I'd have to find a way to compress the springs to get them in? If it's the later, it'd be easier to have someone else (with more tools, proper facilities, experience) to do it.


Thanks for the info!

Will I need adj. camber arms if I'm keeping the ride height the same?
