Default Classic geometry settings?

My car goes in on Saturday to get the geometry set but I have no idea what settings to start with, I plan to do 2 or 3 track days a year so Im looking for some initail settings to take this in to consideration although the majority of my driving will be normal road stuff. I do make one 700ml motorway round trip per month so I dont want to go too aggesive on the settings or I will be killing tyres rapidly and not reraly getting any fun out of them.

I have Camber, Castor front adjustable top mounts, KYB adjustables with Eibach springs and Noltec rear drop links, I also have 215/40/17's Yoko Parada's. The rear isnt adjustable for Castor or Camber at the moment, all help greatly appreciated people.

Cheers for the reply, it gives me an idea on how far I should go. I dont want to go to far with the camber and start destroying tyres to quick, I will be doing motorway driving so I dont want to be leaving swathes of rubber up and down the M6, it needs to be a comprimise but still be of some use in the twisties. I also want a reasonably stable car, less understeer and not to lively a rear end, at the end of the day its not a rally car so Ill have to be carefull with toe.

Ive been reading that you cant realisticly dial in to much caster, I was hoping someone would have some settings for the kind of handling I have described. Ill see what Saturday brings and what the guy is saying to me, I know he has done lots of Scoobs and the like so should have an idea of what settings will give me what I want.

Bit late now but Richard's settings are spot-on for a nice agile car which will be kind to road tyres.
If i were you, copy them!

You might need camber bolts to get the rears in.

Ok these are the settings Ive got.

Front

Total TOE 0.00

TOE LH 0.00 RH 0.00

Camber LH-1deg32 RH-1deg30

Caster LH+3deg22 RH+3deg20

Rear

Total TOE 0.06

TOE LH -0deg02 RH -0deg04

Camber LH-1deg08 RH -1deg02

I thought he would be able to dial in more caster but +3deg20 was the max on the passenger side, to get more caster I would have to dial in more camber so thats that as they say. One last thing, I have camber bolts on the front struts so I could use these for the rears next time I have it set.

Sounds good.
It is the rear camber that can be hard to find the adjustment you need.

Just to be sure - you've got 6' (total) toe OUT on the rear?

How does it feel on the road? Parallel front and toe out on rear is quite radical for road use isn't it?

I run 2' toe in front (each side), parallel rear, and 1.5deg camber all-round.

Its Toe in on the rear mate, its just one of the quirks of their machine. Im liking the handling very much, how do you find the parallel rears?

Like it very much, very 'pointy' but benign when it slides.

Also have D2 coilovers, standard front bar (19mm) and Whiteline droplinks / 22mm rear bar set on max (going to re-set to middle hole on next trackday if wet).

Cool, my next upgrade will be anti rool bars which are std at the moment. There is a group buy on at the moment for Eibach front and rears, Im not sure what diameter they are and have posted to find out. Any advice on what to go for?

One question, what kind of front drop links were on the 93 wrx? I have the same kind as the P1, a double ball joint affair.
