If you are going to spend that sort of money make sure it gets some action.
The suspension job is to make the tyres efficient - ie you really need to define the purpose of the car, then select your shoes before suspension can happen. You can't set up the suspension for every tyre.
Also, be careful when chasing the best. Where are you going to stop? TTX36 will give you a silkier ride than MCA gold for an extra 5k; if you go with TTX46/40 they will be 5k corner plus set up for 0.5 seconds a lap with ball bearing bushings.
