Have to agree with Dan on this, any alignment place worth its salt will listen to what you want. Theres a place locally to me called Hunter performance who have done all my car, specifically a full fast road set up on my Honda. Once dialled it was glorious
As for camber, Id be looking more at the compounds of the trye. All are different and will react differently. I had T1Rs on the Honda and it gripped like poo to a shovel, but wore out quickly. One suggestion I'd make is have the tyres filled with nitrogen instead of air. Doesnt react anywhere near as air to temperature changes, and IMO provided a much firmer but smoother ride. Well worth the 12 quid it cost!
