Wheel Alignment?

[CRA23]

i got new tyres, camber bolts and caster bushes put in the other day and i gave the place the specs that whiteline put in hot 4s for the v6 with what ive done to the car. so i get a phone call a bit later saying that these specs are very hardcore and would destroy my tyres in less then 10k, he said he would only use these specs if he was goin to track race(he said he track races in his spare time) and they were too extreme for exciting street driving, so im wondering what would be a good allignmnt then?

the whiteline specs were
Front:
toe:none
camber: -1.5(Right), -1.75(left)
caster: + 2.5

Rear:
toe: out 2mm
Camber: -1.25 both sides

thx tim

That sounds fine... the camber is about as much as you'd want to go on the road.. any more and it'll start affecting your braking too much... its ok on a track where camber means you just carry more corner speed, but DON'T ever go over two degree's on the road...

Always screw as much caster as you can, so no problems there..

The toe's a bit odd though... dunno why'd you'd want toe out on the back???? Generally you want toe in, as this gives progressive turn in, and helps you setup for a corner better and better mid corner adjustability....

Rear toe out will make the car rear want to rotate further(spin) during cornering, quite handy if you like a nervous, twitchy car, something rally car's love, but not road cars. Toe in on the rear will stabilize its movement to be very predictable during "turn in".Front toe out will give a feeling of wandering in straight line but very quick reaction to small amounts of "turn in" Toe in at the front again stabilizes feel and predictability.

You've also got to remember what a car does under load... 0mm toe on the front static will probably turn into 3 or 4mm toe out under braking, and 1 or 2mm toe in under accelleration... so my advice is generally try and keep the wheels pointing straight under acceleration, cause it doesn't matter if they're pointing out under braking cause it'll actually help turn in...

Someone with mazda track experience may be able to correct me, but i'd start with 1mm out on the front, and 1 or 2mm in on the back, and figurie out wot works for you from there... YOUR driving style will dictate how you set a car up...

oh, and even with those whiteline setting's there's NO way you'd go through a set of tyres in 10k with those settings, so i'd be weary of what advice your getting from him... infact, 0mm toe on the front and 1.5 degree camber, is probably the absolute perfect setting when it comes to conserving tyre wear... even 2mm on the rear, won't go through a set in 10k, i run 2mm out on the front, and 3mm in on the back in the tarmac terror, and my road tyres still look new after 15k...

that's just my experience... no doubt someone like goldsp will have something constructive to say about it....

Tim I am running with those specs minus the toe at the rear and I am not finding any problem with my tyre wear
It sounds like comments from someone who ISNT racing a car on the weekends

i had a similar experience with fulcrum when i had my allignment done. i gave them the same specs as daisy and they said having 0 toe was bad for tyre wear. they normally recommend toe in of 3-4mm or something i think. anyway, i ended up with 1mm toe in or something because they said over bumps and braking the toe goes out to 2 or 3mm so thats not bad.

my thoughts exactally

track would be more like 2 or 3 degrees camber and like 5mm rear toe in....

he might race, he just mightn't be very good at it

[Nate]

he might finish his events tho

[Mattzda]

I bet his track tyres wear well....

[CRA23]

hrmm... interesting, would the toe out have anything to do with the turn in oversteer?

so i will keep the camber the same, make the castor +3 and have rear toe in 1 or 2 mm and the front mabe 1 mm in..

thx guys

YES!!!

sounds good!!! then once you're confident with that, gradually start to bring the front toe out... but 1 or 2mm toe in all round is a VERY stable and safe starting point....
