tyreleader cups performance on track :(

[khooni]

didn't do anything on setup. Don't know how to.

I just wanted to ask if you guys thought it was strange to have performance degrade so much from session to session from a new set of tyres all things being equal.

Guess I must the first person to get a bad set of 2012 cups. maybe it is indeed a fluke set. hopefully. as 2015 sets are pricier by ~£150

I think you've answered your own question, it's fuck all to do with the tyres and all to do with set up

Unless, as he seemed to be repeatedly saying, the only thing that's changed are the tyres (and the track temps) in which case it's everything to do with the tyres (and how he's using them). Whilst a vehicle set up will probably improve things, from an engineering point of view if it hasn't changed it's not the issue.

We're not trying to diagnose vehicle performance here, we're trying to work out why there's a massive difference in tyre performance between apparently identical sets. My guess is track temps and slightly high pressure.

A video would be good so have a look at your steering inputs, just for interest's sake.

thanks for that. At least someone is paying attention. Indeed, I've booked an evening at Brands next week to see if running at 30psi magically solves the issue.

I don't do setup. I let the pros do it. I just try to improve my own so-so driving and to have a bit of fun at the same time. You guys know, there's just so few places to push the car on our roads and feel the sublime balance that they are capable of.
