top pics neil will catch up wiv ya some time to discuss what technique you used
but yeah those DTM are something else on the noise front. absolutely mental but very distinct difference between the Merc sound and the Audi's.
I liked the Merc's...mega screaming but almost vuvuzela like.
The Audi's were bit deeper but still nice.
The Formula Fords / Lotus's by comparison were almost silent. Was a top weekend tho. Did you see the R Cup on saturday?
