What did you do to your Polo today?

How did you chunk rears on a FWD?

I notice your rear anti-roll bar is set to max so was it getting really sideways under brakes?

My fronts looked like that after my 1st track day.

You have a spare set of rims so semi-slicks are the way to go.

i had a few sideways moments under braking

so thats probably why. my fronts faired up alright, a few small chunks out here and there but still roadworthy funnily enough

will look into a set of semis from tirerack soon enough

I did one day at Mallala with those same Dunlops. No such degredation, no 'chunking' or any abnormal wear. Slow down, drive smooth, and remember slow in, fast out.

There's no reason you should be destroying a set of tyres.

More seat time, less push!

it was my first time, so i was prepared for a little carnage

Mallala doesn't have the long corner linked sequences like the old portion of Winton so the tyres don't heat up as much and get more time to cool before they're loaded up again.

I'd try easing the setting on the rear anti-roll bar next time, hazrd. You're probably getting the inside rear almost off the deck in early to mid-corner phase of the turns which is what's beating up the rears.

Mine has similar tyre wear/rubber build up on the back as it does the front. If the car is balanced, it should be reasonably even wear and you've balanced the car through the corners and not over working the fronts. I have measured the tyre pressure after the sessions to find much the same increase in temp front to rear, left front slighty more than right front given the right hand nature of the track (QR), but rears being the same.

I've also found that as you do more track days, you do learn to be more gentle on your tyres while doing better laps times. Your braking and steering will get smoother, resulting in less heat. You'll also get a better feel as to when your road tyres are about to turn to jelly, so a slow lap to maintain temps will improve longevity and lap times.

Cool, thanks for the heads up

I did have a mate checking the pressures and also the temps with one of those laser gun thingos and they seemed to stay pretty even which i was happy about (give or take a degree).

If you do, can you find out how much 2 sets of these would add to shipping?

The key for beginners is to start off not even worrying about braking and to concentrate on the best corner entry point and speed that allows for the fastest exit to "open up the corner". Then as the day goes on they can work on braking points while maintaining the same turn in and exit as when goingin slower. As well as helping with consistent improvement, it prevents the tyres from being hammered by sudden, inappropriate loadings (once you're going fast enough, the loadings WILL be sudden but by that stage, you'd have a good feel for the tyres and vehicle capabilities/limits).

Of course, getting someone to take it slow on their 1st track day can be problematic
