Introducing.. j0nbubz!

^ I'd have to agree ichi-go!

Definately feels wobbly going round round-a-bouts!

What is the best way to reduce the body roll? I was thinking thicker rear sway to begin with (as it already has coils)

 

[raytsang]

well ive coilovers, front and rear sway bar (adjustable), rear sub frame locking collars, full alignment kit (rose joint) and light wheels/ potenza tires. :thumbs:

have to say its alot more stable around bends then stock, really makes the difference. just had mine all set up and turbo blow so didnt get chance to test out its full potential.:annoyed:

 

[j0nbubz]

sounds like a good setup ray

what are the locking collars used for?

also - would you happen to know the stock F/R swaybar sizes for jap-spec?
with this - how much thicker would I go for a front sway to more-so neutralise the car

Like many other modern RWD cars, the rear suspension components and differential are mounted onto a subframe. The subframe is then attached to the base of the chassis via four bolts. Rubber bushes are sanwhiched between the chassia and subframe and tighted by the 4 bolts.

The rubber bushes provided as insulation materials to absorb NVH from suspension and drivetrain for comfort and silence in cabin. However, it caused the rear of Silvias to loose feedback and steering response. Even in high speed (> 220kn/h) cruising, the rear wheels gives the creepy feel of wobble left and right.

To nurse the issue, many Japanese tuners offer bullet aluminium alloy collars to be slotted into the rubber bush locations. This clever approach eliminates the need to change the rubber bush material yet acheive a tight feel for the rear suspension. However, the down side is that more NVH now gets transmitted into the cabin.....hehee.

Stock wise the s15 feels wobbly for some reason.

ichi,

Perhaps your S15 had too much booze...

 

[j0nbubz]

mine has had WAY too much to drink then.. HAHA!

 

[raytsang]

like what sillbeers15 said....

when the wheels do staart spining they dont wobble so a plus side when drifting... hehehe

Subframe collars alone will have a dramatic effect on the tightness of the rear of the car. Decent sway/anti roll bars will reduce roll noticeably. Coilovers will also reduce roll and allow you to adjust height and damping. All the other alignment stuff is needed once you lower...

Hello and welcome :wave:

I noticed last night that when carrying speed through a roundabout, then accelorating out, the car seemed to bounce/bog down until settled then pulled. just when accelorating and turning, any ideas? Damper set to soft?

 

[j0nbubz]

happens to mine as well..

I would have to say it's a matter of damper..

Is this the first time it's happened.. or..?

 

[Topper]

1st time i've pushed on through a roundabout like that, yes. However, i have been on tight twisty b-roads and not noticed it. I think i'll tighten up the dampers and see how that goes. :thumbs:

A bit late but anyways.... Welcome :wave:

 

[j0nbubz]

wow still getting email notification of replies.. =P

good news all!

just got my genuine aero front bar fitted (sun has warped the edges a bit -.-,, needs some bashing!) + my rims are arriving on Friday!

joy =>

 

[ichi-go]

Where u got it from and how much if you dont mind me asking. damn aero bars are tempting

Have you seen this thread

I love that thread. Where I got my first love for the aero bar!

FYI: got my aero with factory fogs for approx $1000 delivered to my city. Got it from yahoo auctions

 

[slammedmind]

hello and welcome mate!

 

[ichi-go]

yes yako i've seen that thread, dont wanna see too much though, gotta resist tempttttaaaaattttiiiooonnnnn

 

[j0nbubz]

s15 aero front bars are so expensive..

a mint cond. one in australia will set u back over $1300

I got mine for relatively cheap.. has a few chips, colours a bit off etc

 

[ichi-go]

They are expensive because people sell theirs for too expensive. If you know people around, u can get them relatively cheap, less than 1k for sure
