993RS & 964RS in the wet
Discussion
Any 964RS with no cat and a cup pipe fitted will get in, Pete Morris runs his car regularly on these days and has no problem at all.
Tim can be reached on 07774 665888, he will organise the event on our behalf, any interested parties please call him direct and ask him to send you a schedule or just to put you on the mailing list.
I have driven on these days a lot, and although there is usually a fair mix of cars, the driving standards are usually fairly high, although they do not like all out racing under any circumstances.

Ninemeister,
I have a 964 RSR (Club Sport), which I use purely for Track days. I run Michelin Pilot Cup Sport (steady!) in the dry and damp - will try Pirelli P Zero C's next time - which I know you prefer, but I am looking to buy a second set of wheels for the wet, and I can't decide on which tyre choice to go for.
I currently have a set of Pirelli P Zero Asimmetrico and they are scary in the wet on track. I had a racing driver in the car with me going around Donnington Park, and even he commented how bad they were - or maybe it was my setup/driving?
Current thoughts are:
Full race wets - relatively cheap £80-90 a wheel, good in wet, will destroy them if it dry's out too much - good choice if you can afford 3 sets of wheels - I can't :-(
SO2's - stopped making them :'-(
Toyo Proxes TS-1 - Seem to get very good write-ups, especially wet weather handling. Don't know how they work with a Porsche?
Thoughts?
Cheers,
Mark

Regarding wet/road tyres, try finding some Bridgstone S02a's, these are the replacement for the S02.
Regarding dry tyres, I have always liked the P Zero C and I could not live with the "compromise" of the Michelin Sport Cup at all. A lot of my customers are using the Dunlop Formula R D01J and rave about it, but it is not made in the usual sizes for the 964RS unless you have 18" wheels, when their 235 & 275 will fit (believe it or not). My mate Pete (Mad Man) Morris runs the P Zero Corsa for his sportscar races and likes them. I have heard that Yokohama are doing the right size for the 964 on 17" but the supply has always been patchy, and finally I have been trying to get a set of Kuhmo tyres all year but their UK operation is a farce and never return calls to trade, so I gave it up as a bad job.
I'll do the usual run around at Autosport and see what's available again, but my recommendation is for the S02a and P Zero Corsa.
As for the track day, all get in touch with Tim, tell him I told you to call, and let's pick a day from the schedule early next year. Maybe we could combine it with a bit of a get together the night before??

Thanks for that Colin!
Also, spoke to Silverline and they echo your comments on the Michelin Sport Cups, so I will definitely go for the P Zero Corsa's next time.
As for the road/wet tyres, again the tyre of choice seems to be the SO2, but with a slight problem of availability. Even if I could get a set, I am not sure I would due to such limited availability. What happens if you shred a tyre, and you can't replace it.... stuffed!
So the second choice by Silverline is the Yokohama AVS Sport, which they have done a lot of testing with. One of their customers who has several track Porsches and does around 70+ track days a year, has tested most makes of tyres and this has been the tyre they have come up with. (Note his preferred choice was the SO2 as well). Anyone experienced these tyres??
Can someone point me in the right direction of Tim for the Track day?
Cheers

I am interested in the Oulton trackday - when is it?
I have just done two very wet Oulton days and was suprised at how well the car (964 C2 9M suspension SO-2s) behaved in the wet - hardly anthing passed me in the wet, which makes a change. Unfortunatly things are not quite so good as the track dried out as the tyres appear to overheat and pressures rise rapidly.

I was stunned at how good a donated, trashed set of S02's were on my Cup Car. Good in the wet, and fine in the dry, as long as I kept lowering the pressures to 32 hot all around. When the rears went up by as little as 1-2psi, the back of the car went squirrelly, and it was time to come in to lower them again.

I spoketo Tim yesterday, heis still awaiting dates for next year from Octagon (Oulton Park owners). As soon as he has these dates, I will post another thread with his details, the dates, the costs etc. What I am conceptualising (asuming we have the numbers)is to get together the most 964RS & 993RS models ever on one exclusive RS track day, no cup cars, no replicas, none less than 3.6, so we can all talk out of our RS all day and have great fun at the same time.
However, until Tim has dates, if you are interested contact Tim (not me) and get on his mailing list so we can both start to plan ahead.

What's wrong with Cup Cars Colin? -the RS was spawned from them. I don't think you can afford to be selective..........

PS MURRAY -try 28cold, 32 hot, and keep lowering to 32 immediately after each session. Have a lot of fun -my favourite track!! Grab Malcolm Hamilton for some instruction if he is around.

My last two days at Oulton have been very wet and I ran my SO-2`s at 36psi and the handling was fine.
I measured pressure when I arrive at the track at equalized them at 36psi ( if its dry I`ll drop them to 32psi at this time) and then check them after every session.
Melv has a cup car which is a bit lighter than mine.

Go with Vsideways. Plus, if u read Paul Frere's book, he explains that on, I beleive, a model change in the '70's, Porsche realised that by jacking the rear tyre pressures way up, the rolling radius was increased, there was less friction, and therfore the car had a higher top speed and horsepower!! THAT is why. (Just spent 5 mins trying to find the relevant page, but u know what it's like when u r searching in a hurry -no luck!)
Frankly, I think the cars feel diabolical on the recommended 36/44 pressures and I'm sure the high rear pressures only serve to promote spins!!

>> For one thing the tyres are different sizes front and rear, and for another the car is not balanced 50/50 weight.
Realise that but people here recommend same pressures all round. For normal road use I normally run 34/38 but no no other reason than I read somewhere that the 36/44 was too high. Is it all to do with weight as if I remember correctly my normal road car is front engine, rear drive but still has higher pressures at the back.
