Default Setting up more agressive alignment for the track

Hey everyone, I have a question in regards to settings for an alignment on a staggered setup. I'm in the process of getting ready to raise my car and with that leave the UK alignment settings behind for something more aggressive since I don't daily the car. My question is in regards to the rear camber, It seems most people that have gone down -1 degree in the front complain about having too much over steer. When reading through most articles and forums though the pro's recommend a -2.0f to 2.5f and a -3.0r.

Right now I'm running a 225/255 setup and I don't really intend on changing that. I like the way the car feels despite not having enough clearance and hardly any suspension travel at the moment.

What I was considering running. Just not sure if I should match the f/r camber or not considering how I didn't mind the 1 degree difference on the UK alignment.

Front Caster 7.5
Front Camber -2.0
Rear Camber - 2.5
Front Toe 0
Rear Toe 1/16

I'll bet that would work pretty well. I'm running -1.5F, -2.0 rear on my car, which sees only street duty so it doesn't have as much need for negative camber as a track car.

I feel the smaller camber bias (1/2 degree vs. a full degree) of this setup vs. the UK setup helps the front end stick better. In my case, I think I need it because my DFV suspension has a little more front roll stiffness proportionally than a stock suspension. In your case, it might give more neutral handling for track usage.

Your toe settings are almost exactly what I'm running. I'm happy with them.

Damn I didn't see the suspension tuning section before posting this. Mods can you please move this for me? Thanks

Sounds good, I'm sort of just starting to learn about all of this and have tracked the car 3 times on my current setup and felt good about it, Surprisingly I haven't found a need for a bumpsteer kit either like most said I would. I guess its possible that with the change I might need to get one but we'll see. I assume you are also staggered as well?

If you have semi race tires they often recommend -2 or more camber. The manufacturer of the tires you buy usually have specific recommendations for there tires. Also by running 225 in front and 255 in the back will give you understeer under hard cornering try to have the same wide all around.

Front Caster 6.5 (I wonder if +caster contributes to wishy washy steering center feel)
Front Camber -3.0 (with solid/hardened bushings -.25 more without)
Rear Camber - 2.75 (with solid/hardened bushings -.25 more without)
Front Toe 0
Rear Toe 1/8

This is not necessarily true, it depends on the roll stiffness at each end. 225/255 can easily be made to handle neutral. Camber depends on your roll stiffness and tire choice. You want the camber that will give you even tire wear and tire temps. Having said that, your proposed settings are a probably a good place to start.

What tires and suspension do you have?

I'm really glad that I asked you guys before making my appointment. How does your car react with those current settings? and what was it like before?

hmmm interesting. It could probably be done considering I'm raising the car now. I thought about it but I had felt so content with the 225's I didn't really consider it much. As of now, the oversteer really hasn't been bad.. Right now I have the old Starspecs in the front and RS3's in the rear.
