Williams' Track '6 Bit of weight saving ;) + shortened wheel base

29-33 hot for the rears!?

See cullys photos from combe to see what happens when you run too much pressure on the backs into camp!

Yes. It's what they are designed to run. Same goes for most road-track tyres. Only slicks should be run less.

My rear tyres went up 6psi on Friday and it was warm out (23 degrees). After 5 laps but with a fair bit of brake bias set. 

It's very dangerous running too low pressure, tyre can come off the rim etc. Car feels awful with less than 27 in the tyres and I carry a load more speed with them at 31-32.

I'm using kw v2s but using different springs. You are very likely to get inner rear wheel lift without the arb. Happens fairly suddenly on standard suspension, hence the lack of grip
