Hi

In my opinion the PD manifold is very expensive for what it is..... Although as good as it is...

Ellmer Motorsport in Germany is the company that keep advertising those manifolds. He can do them for £500 delivered.

As for tyres i don't like the standard PS but i am told the PS2's are about the best tyre available... Eagle F1'a are ok as for the Toyo's you will need R rated not S. The S are the sport version they will not stand up to the punishment the FRS will throw at them. I have Perelli P-Zero Rosso on at the mo and i have been ver impressed. Not the cheapest and not the most expensive..
