I have abour -2 camber, how can i get a little more, say to -3

 

You may find if this is a street car 2 is more than enough .

 

Do you actually have -2 now? Every GP I have seen has been in the range -1.3 to -1.8 (with no load in the car).

If you want more you can add a set of camber plates. That will allow you to get to around -2.5 before you start to have problems with the top of the shock fouling on the strut top. However, adding a camber plate will add to the stack height of the suspension, and raise the ride height slightly.

If you are going to add camber plates then it probably would be wise to convert to 60mm id springs at the same time, as a new strut top to fit the springs could be integrated with the camber plate. That gives you a much greater choice of springs to play with, both in spring rate and ride height

 

How about a ball joint modification to increase the camber. Has anyone tried this?

 

Why do you need more camber??

 

Has anyone expermented with extending the camber adjustment slots by grinding out a bit to get a little more camber?

 

A better solution would be camber plates, to be honest.

 

Porsche1vw can I ask why you want more on the front? And what will you take your rear too? Just curious that's all, as I've been playing around with some alignments of late.

 

It's possible but I wouldn't recommend it. You're weakening the strut tower which is already not super strong. Plus you would have to do a bunch of grinding depending on how much camber you're looking for.

Camber plates are the droid you're looking for

 

Some of you have asked why I want more camber. Well, I am an autocrosser (& an engineer). I have previously developed a number of national championship autocross cars. I experiment and test a lot to optomise autocross performance. Many tires I plan to test have a reputation, and have previously indicated through testing, that they like about -3 degrees of camber - for example the Hoosier A6 tires. Need I say more?

 

Porsche1VW, i also autocross my mini and i have -2.4* of camber in the front and -1.7* in the rear and i find that is more than enough with good R compound tires. I have absolutely no tire roll/sliding, the car is controlled through all the turns INCLUDING the V turns.

For reference:
bilstein pss9 coilovers w/ vorshlag camber plates w/ cravenspeed reinforcement plates

Polyurethane front lca bushings
Alta 22mm rear sway w/ hotchkis adjustable LCA for the rear.

 

How about why you're banging your head against a wall running a mini with what sounds like stock GP2 suspension in DSP or SMF?

We run about -3.2 degrees of camber but on street tires. That is with the Vorshlag plates maxed out. With the 450lb front springs the tires do a pretty good job of staying in their "happy place" with regards to camber. Lots of photos and pyrometer measurements to confirm. With more grip you'll obviously need more spring or caster or camber. Camber is probably the easiest one to achieve for you.

 

How about a modification to the ball joint to incease the camber a bit? Has anyone tried this?

 

I've not seen anyone try it. It's certainly possible although with sticky r comps I wouldn't trust it. Someone could manufacture an aftermarket outer ball joint that would increase camber though. But you'd be widening the track which is generally a bad thing in auto-x.
