Had virtually the same set up as you it would appear. Just ended up with 45wt oil in front shocks. Ran a Novak 6.5L 20/87 - did get a bit warm.
Started with 'euros' set up with 1.4 roll bar in practice. Changed springs & front oil by round 3. The car still 'pitched' in (if thats the correct term) sometimes on the bend in front of the rostrum. Other than that, brilliant.
The weakest link was definitely me
My car got 'lost' in one of the heats. Was behind the tabe top, none of the marshalls saw it crash, just a mad bloke on the rostrum shouting & pointing
