Browns used to do all my track day wheel alignments, though I havent had a need for this sort of thing in a few years.
I'm not sure I'd completely trust SwedeSpeed as my 'source of truth' if you're seeking a performance/motorsport wheel alignment but it might serve as a useful starting point - the key, of course, is getting someone who understands their alignment rig really well and is interested in doing a vehicle that, to them, is a be unusual and then being willing to pay for an appropriate amount of time to get it done.
This service, as I'm sure we're all aware, is a long way from the wheel alignment that Jax or Bob Jane do when we throw some new tyres on a typical road car.
