[platypus]

hmm i'll get back to you on all gb's... just call me boyd....

[twilightprotege]

hey arden i cant find it, but how many did we have to get in a GB to get a discount?

[arden]

Alright,
right now, not that happy.
came out of Whiteline with back tyre flat.
they rang me up soon after sayin they noticed it flat as i was drving off. Of course i was thankful.
pumped it up at servo....it was completely flat...5psi. so drove to work...tyre looks decent.
but i hear a small leak.....so im screwed. Gonna take it to bob jane for patch up.

ok onto the swaybars.

Another BITCH i have...THEY USE THE SAME EXISTING REAR SWAYBAR!!!!!!got charged like full price!
DAMN DAMN DAMN.

Front bar is 24mm. $180 full price. So u guys are lucky there.
So not much point in organising group buy, which they need 10 ppl and will take 10% off.

Results: Bit hard to tell when its pissing down...but body roll is reduced dramatically.
Goes into corners leaner and meaner.

Does anyone know how hard these are to install in our cars?

[arden]

guy was tellin me its a pain to install.
as front control arm has to be taken off.

[chipa]

doh! Thats what I afraid of. Doesn't sound like the front is something I would tackle myself. Probably do the back and then pay someone to do the front for me.

[twilightprotege]

what what what?

same rear bar? wtf?

those farkers!

they reckoned that the rear bar was matched to the stock front bar, but then they make the front bar bigger and the rear is matched to it? wtf?

arden what's that tossers email address - i have a few words to say!

ps - damn screws!

[arden]

yeh my thoughts exactly. Doesnt make sense.

flame away.

You had the stock rear bar on when it was delivered and they didn't change it?

If they have gone stiffer on the front without lifting the rate of the back all they have done is hamper your cornering ability.

Just before we get carried away what other suspension mods have you got? The possibility EXISTS that for your springs only increasing the front MAY have been beneficial. I am in no way condoning their course of action so don't flame me.

Personally I would say that by increasing the front bar rate it would follow that the rear bar rate should be increased in proportion over that of the stiffest BFR59Z setting. That would be my take on it.

Arden I am disappointed firstly that you have been charged anything for them to develop a product which may well sell like hotcakes. To me that is shocking business sense.

[arden]

They used the current whiteline rear swaybar...the bfr59z.
Suspension mods, are Kings Low Springs.

Im a bit shocked they charged me so much for it.

the guy there made a huge deal how much i saved on labour.
and i got like 30 bucks off the new front sway bar. like WOW.
:roll:

[arden]

oh, wot is stock size on rear bar???
forgot to mention they set it at 20mm, not the max 22mm setting.

[arden]

Andrews, found Pete's famous words

"The existing range of rear bars are designed to match and balance the OEM front bar. Fitting a larger front bar will require a new rear bar and we would therefore design new rear bars to match and rebalance the chassis etc. "

[SFC01]

The larger front bar + bfr59z will be a huge increase over stock. What may not have changed is the understeer/oversteer balance of the chassis.

I don't find the stock 1.8 front bar + stiffer BFR59z setting overly tail happy on dry bitumen. It may not be optimal for everyone though. The rear is well and truly willing to come around on dirt.

So you have uprated front AND rear bars. That wasn't so evident from your first post. You should still find some room for adjustment if they've left it at the softer setting.

Were you provided with any traction circle/skidpan data to compare OEM to your setting? If not I'd be pushing to get some of that info so you can see quantitatively what difference there is on your car.

[twilightprotege]

do you have pete's email addy? i'll email them both and see what the hell they are on

[arden]

Scot,

i was provided with a tax invoice and wheel alignment settings.
i will ask for the other data u mentioned.

[twilightprotege]

arden you swapped back to the original bar before taking there right?

[arden]

switched?
was stock all the way...apart from springs

[ezin]

Considering the mazdaspeed protege has F=25mm and R=20 I would say they have set it up with a neutral setting which is good! Neutral is good so dont be to quick to flame the guys at whitline. Even if its got the same bfr59z bar on the back, are u happy with the way ur car handles around conners cause thats all that matters, U still got two bars (1 designed) and a 4WA (which is a prick on a lowered sp cause the lazers get blocked and u have to remove all the plastic covers under the engine) I think U got a good deal.

original email i sent to peter and wojtek, reply and it's reply to follow :

Hi Peter and Wotjek,

I just had word from Arden Wong that he has his yellow Mazda Astina SP20 back with the new sway bars. However, I think there is a problem.

Originally Peter you said that the current rear bar available (bfr59z) was matched to the stock front bar, however when the new front bar was made (24mm - a 2mm increase over stock), the current available rear bar was used. That makes no sense from your original statement.

To quote, you said "The existing range of rear bars are designed to match and balance the OEM front bar. Fitting a larger front bar will require a new rear bar and we would therefore design new rear bars to match and rebalance the chassis
etc."

So what went wrong or what happened? I would have thought the front bar would have gone to 25 or 26mm, and then a rear bar made to suit, 21 or 22mm.

So could you shed some light on the situation? I'm quite disappointed with the outcome of this exercise. I feel bad because I asked Arden to do our small Astina community a favour and donate his car for a few days. Arden already had the bfr59z rear sway bar. He sold it so he could change back to the stock rear bar so you could do a complete comparison and upgrade.

In addition, what were done with the mounts?
