As the nats comes near. I went to get my car wheel aligned.

I went to Stuckey race tyre service for a professional help.

After talking to them about my car (with the old setting) and my feeling of the latest track day.

My concern were:
Too much wear on the outside.
Too much understeer in fast corners and some understeer on braking.
I still want to drive the setting on the road.

My setting already -1 degree chamber and dead right L&R, F&R... so he suggest a little bit more -ve camber, and end up have -1.3.

He set near zero toe in the front and reduced the massive toe in at the rear (I think the toe was out after the last track day)...

The result:
I think the steering is heavier, more sensitive and not yet turning hard enough to see how it reacts, can't wait putting on the track.

Does anyone can share their experience?

I found this article... very interesting and informative

Excellent site Taka.... My car has been pulling left for a long while now.... Caster... +ve is needed perhaps a lttle more on the left that the right I think...

Cool Taka, do you know what is the specification of the 8 from the factory?

takahashi

It certainly helps a little....

I was told that in term of tracking, toe in in the front will makes the wheel goes "under" when doing an opposite turn in. Does it make sense? So front toe in will reduce the negative chamber effect of the front wheels. Zero toe will be the best.

The con of the front zero toe that a slightly out alignment will cause "wondering" or straight line instability. It certainly has been talked about in the article above. And race car does not mind straight line instability .

No idea... it is so hard to read the owner's manual. It depends on the vehicle height I think.

Front: From -0.45 to +0.26
Rear: From -1.4 to -0.4

They have 1-3 inch toe in front and 2-4 inch back.

I already set of -1 chamber when I have my new Enkei's and had I had a look on Saturday and the guy said said the inner shoulder is still ok for -1 chamber and can take more without ill effect on wear in normal driving. I am using Michellin PS2 as the road tyre and on 38 psi.

Toe should be set at zero front and rear.Front negative camber as much as you can get-usually only -1 1/4 to -1 1/2.no problem for road use.
Rear about the same.
This set up works well on and off track,with no ill effects re tyre wear.
Have your alignment checker prior to the Nats-it doesn't cost much and can make a huge difference to your handling.You'd be suprised how far out it can be straight from the factory.

Not just following road camber is it xxup?

Not taking the **** - serious query.

I just did the same last weekend. Had more negative Camber added and Toe taken out.

So should I blame Ricky's setting for only getting 1'31 in the last outling Stu

I found the DSC engaging quicker to understeer in the Mt Dandenong today, but yet I am in a higher speed.

Love the set up, I think I can have less toe in for the rear. I better have a couple of track day to test the set up first :D

I plan on getting wheel alignment done tomorrow. I assume they will reset according to the factory settings.

So, if I ask for more negative camber and have the toe taken out. Then what figures should I quote.

BTW, I am also installing whiteline sway bars...how does this effect the settings that I ask for. Thanks for your help guys.

No because when I drive on a highway with a camber on the right it steers nearly neutral or has a slight pull to the left.. Where I live the cambers are pretty severe and I seem to be fighting the wheel all the time... No fun driving it at the moment..

takahashi

No I don't think so.

The endlink seperates the toe, chamber, caster setting from the sway bar.

skc

Very happy with my handling after adding Whiteline sway bars and changing the toe and camber settings front and back.

This combination makes the car very responsive :D :D

Grand Prix fixed my wheel alignment... It now takes more than three power poles on a good camber before it wants to smack the rims into the gutter...

Well done boys...

I need to get GP to check my wheel alignment. Drives a smidge to the right with the wheel straight ahead.
