Skyline Nationals - Mallala Sprint - Sept 12

[Blue]

Yeah what i have heard about the toyos is that they are softer, so good for light cars, out laps or short motorkhanas and hill climbs, but go off quickly after multiple laps in a heavy car (eg a GTR ). Ive got no direct experience in that though so could be totally wrong.

As a matter of interest how much does your car weigh?

The car is about 1260KG with a driver and "Some" fuel (I can not recall how much we had in it at the time, probably 20L or so)

I bought the Dunlops (Whoops, 03G not 01G, just had a look) at the start of this year as the previous set of 888's were well down and I had a wet hillclimb coming up, no one had the Toyos on the rack so I grabbed the Dunlops, when I bought them Stuckeys (Melbourne) reckoned that the Dunlop was the softer of the pair.

There are three compounds about in the R888. G, which is the hard one, GG which is the meduim (Which I have) and GGG softs, which would be unusual to see, indent order only. The Dunlops are sitting in the shed as our sponsor pitched in a set of the R888's before the Phillip Island 6 hour so we pulled the part worn 03G's off and shedded them until the Toyos wear out so we had brand new tyres going into likely wet weather at the 6 hour (Which turned out to be a beautiful weekend)

The Toyos did about 500KM around the Island at a relatively relaxed pace (2:00 lap time nomination for one bloke and 2:06 for me, where the car as it is should be good for somewhere in the low 1:50 range) I reckon they are about half worn out.

There is a much softer Toyo that I would not use on the R31 for anything but a hillclimb, the RA1. I think they are the Toyo wet compound. One of the blokes at Mallala was running them (And going pretty quickly) but reckons they were pretty old and hard. I think in new condition you would melt them in a sprint on an R31.

I have had the Toyos go off but that was at a Winton Sprint on a 35 degree day doing 15 minute runs, they started to get a bit sloppy after about 10/12 mins at sprint pace.

yeah that's a fair bit lighter than the full trim 32gtr - 1460 + 90 kilos of meat behind the wheel + 40kg of fuel = 1590kg.

my typical session would be 1 out + 5 flying laps @ ~1:22 = 6m50 at full sprint pace, A048s hold their own over that distance, Toyos might not like the extra 330kgs still, when the a048s run out i'll be looking around for something else so might see if the harder 888 compound suits.
