Interesting you gained corner exit grip by raising rear camber, for me on RS3's I found that taking out camber in the rear added grip (understeer) on corner exit due to being able to put down more power. I was experiencing oversteer on corner exit when I got on the gas with a higher camber setting. Which makes alot more sense to me than adding camber to gain rear grip on corner exit. Hens the reason drag race guys run zero camber for added grip?

Not saying your wrong or anything. Just interesting it work out that way for you. Now if you told me you added more camber in the rear for added mid-corner grip I would of agreed with you. Maybe I'm to agressive with the throttle and need to become a star spec user for the added longitudnal grip.
Josh: i would have thought rs3's would be the quickest tyre?

The star specs have more longitudinal grip so theoretically you could run more rear camber on the car with these tires over the kooks.

I could be wrong but when we are talking about corner exit increased rear camber would decrease longitudinal grip, which would increase corner exit oversteer because your on the throttle during corner exit.

Not that guys findings though.

No you are misunderstanding me. For my setup 2.5 was not enough to sustain lateral grip so I bumped to 3.0. Lowering the rear helped my corner exit. The Camber helped but was not the main factor in improvement.

Does the negative rake cause issues with turn in response and understeer?

What about lower ride heights in general, has anyone tested if there is a significant benefit from dropping the cg by going really low...say 13" to 12.5" to 12.25" etc?

Lower rear height is determined by how you are able to corner exit. Lower the rear until you start to have on power understeer then go back up a bit.

So how do you set front height, and in relation to rear?

Is that a real question?

Yes sir, it is a real question. To be clear, I mean if rear height is determined by corner exit traction, what determines how to set front height?

Also I thought I read somewhere suggesting not to run lower rear than front heights as it causes turn in and understeer issues, that's why I mentioned that. I looked and found the post, it was by you, a few months back:

+1 on the lower ride height question. in my case, going from 14" to 12.8/12.6"

Ah there was something else wrong with my setup back then. I haven't had any ill effects of negative rake recently. In regards to response with the front end there shouldn't be an issue. Set front ride height where you want it and start lowering the rear for corner exit. If you sstart to go too low in the rear I suppose you can start raising the front.
