We tend to drop pressures to keep them 31-32 all round BUT tbh what you really need to do is check pyro readings across the tyre to get middle and edges within a tolerance so that's tyre is no overheating in any one spot.

Depending on geo that might mean different pressures at each corner as you can't alter geo at track easily

As Barry did I set my pressures to 31PSI all round after a warm up lap.

Felt at those pressure's after about 10-12 laps (depending on traffic) my tyres went off a touch

Going to Intrax, if you can't beat them join them

Only driven standard suspension to Intrax, Huge difference IMO

Phone Ant @ Simpson motorsport if you go for it

The off was in a straight line. Last time at How Fast I said to you it felt wallowy, same again at Donny, maybe need stiffer springs as these are 80f 45r.

If I change spring rate I might aswell change the lot as I don't know whether the Nitron dampers would cope.

You could have done a couple of laps in mine to see what you think before spending the money. Your welcome at Silverstone to compare if that helps

I think at those speeds any tyre will go off (Toyo go off after about 4 laps)

Intrax cope with 3 different rates for the 1k2, so I'm sure that the nitrons will be fine too?
