Hello!
Been reading the FAQ, and numerous topics about geo set-ups around the forums but I´m still a bit puzzled on what to go for.

I´m currently in the process of replacing my seized geo bolts with new ones, and installing a full Polybush kit.
I will be running 255/40/17 AD08.s in the rear, and 235/40/17 in the front. (Rear wheels are 17x9" ET45, Fronts 17x8" ET45) (If anyone has any opinions about the tire sizes I´ll be happy to hear them too, still thinking if I should go for 245 + 225 or 255 + 235 combination..)
The car has been lowered on BC-Racing coilovers.

The car is a daily driver, but I take it for fast runs on the country-lanes and twisties very often, and also drive it on the track several times a year, so handling in those conditions is the #1 priority. (I wouldn´t want to ruin my new expensive tires right away though.. )

Any ideas on what kind of setup I should start with?
I´m trying to gather information on how each setting will effect how the car handles so that I could learn to make adjustments of my own if I want to change the way the car handles.

Thanks a lot in advance for any help, and sorry for making yet another topic about geo-setups.

Edit: The car is an MY03, forgot to mention that earlier.

 

Have you got a bumpsteer kit? (steering rack spacers and rear toe arms)

If you do then have a look in my topic for my settings, if you don't then wait for the wise people to come and suggest setups

 

How you planning on adjusting yourself? You tweak one thing and the other settings are affected.

When I was planning changes I researched and pondered what I thought was wrong, my car wasn't stable was the big issue as the rear toe was screwed. Other than that depends on how tight you want the rear, how you trade grip vs driveability etc

I think the stock settings result in a car which breaks pretty quickly, ie quite an aggressive setup

Decide what you like and don't like and go for fixing that

 

May have said that in a way that can be misunderstood easily.

I am aware of that, and was thinking I´d just go get the geo adjusted again in the future if I want to try something else, or want to change the way the car handles.
Just looking for a "Benchmark" setup to start working with, since I´m pretty sure the stock geo won´t be very effective with all the changes I´ve done.

I don´t have any anti bump-steer goodies yet. Have been thinking about making my own spacers (Any idea how thick the factory made ones are?) and getting a set of rear toe arms.
I suppose the stock rear toe adjustment does not have enough travel and that´s why I will need the adjustable arms? Going to look for a set right away. Might as well change them now since I´m pretty much changing every wearing part in the suspension & brake system.

 

Spacers are a cm thick iirc. The rear OEM toe arm have soggy bushes in which give too much movement which means you need a lot of rear toe to keep it toeing in. With the replacement ones you can run a lot less toe which is better for your tyre wear and it makes it a lot more predictable.

 

I already put polybushes in my OEM arms, but I guess it´s still better if I upgrade to arms with uniball-mounts?

 

Definitely. The hardrace ones are the best by a country mile...easily the best engineered.

I'd go for standard tyre sizes.

WinFreak, I've just ordered my Megan stuff from the states. Are you runniung less toe now? I have 0.14 & 0.11 toe in at the rear at the moment with a standard setup plus Eibach springs -2 degrees or camber at the rear.

 

I've got 0.14 overall iirc, but with more camber. If you have a look in my topic there's some discussion about it on the 1st page.
