Track and Road Tyre Query

I have just purchased a 1992 964 C2 with 'RS Suspension Setup' and bypass and cup pipe etc.

It came with two sets of Cup 1 Wheels and tyres as follows :-

9,000 mile old Bridgestone SO2 road tyres - 225/45/17 and 255/40/17

Michelin Cups in same size but slick on left rear, almost slick on right rear and on the legal limit at front (or just above)

I have ordered a set of new SO2 (Porsche N3) in the same sizes to use as my everyday road tyres with new tread for winter - being fitted 16/11

Question is - should I junk the only just legal front Pilot Cups and then use the set of old SO2 as track tyres (not that good according to Hamish) - I am no Sebastian Vettel :)

---- or should I keep the old SO2 as spare road tyres (very useable when new ones wear out) and buy new rear Cups and run the just legal fronts etc. etc.

There are options but I am not convinced my driving can get the most out of Pilot Cups, and it is a lot of money for a few track days ....... and what if it is wet.

Any help and advise appreciated......nothing will be binned (except the slick rear Cups, although do they work as a slick track tyre ?) as yet.

Not sure if I understand fully what you're saying but if one option is to run road tyres on one axle and track tyres on the other....I would advise against doing that. I think you would indeed need to have 'Vettel like skills' to manage the different grip levels [:D]. I'd also be wary of thinking of a balding track tyre as being close to a slick....a true slick has a lot more rubber on it.

Regarding the option of buying some new MPS cups....let us know if you can find them in 17s because in my experience they're very hard to source new (the best I could do was pick up a set of part worn that came off a car that raced in the PCGB championship this year).
 
No - No mixing of tyre types.

Wanting the view on using older SO2 as track tyres or whether they are just awful

......, and if so, can I run only legal limit MPS Cups on front if I take them in the car with me and buy new for the rear - can I fit track wheels in the car with me....how do others transport them ?

Pretty sure there is no problem getting them. My friend who now owns the 964 I used to have recently bought a brand new set of 4 MPS cups for the 17 inch Cup 1s on it. There is only one or two dealers I believe and I can find out who he bought them through if you want.

For track days old SO2s are OK to get started. You will want to move on to something else, but you'll be able to have good fun with them. My car came with a set (still have them), happily played for a few days before I bought better tyres. Only made a couple of seconds a lap at most, probably less, which isn't going to matter on a trackday anyway.

[damn! I'm paranoid about spelling now.....is that how you spell paranoid?]

Details of the supplier for the 17" MPSC would be good.

Sounds as though the old SO2 will get a look in, and then new MPSC will follow - easier on the budget also.

Should get the new SO2 tomorrow. All in at £530 a set.

Yes they still make the SO2 N3 - Kwik Fit had 25% off all Bridgestone, so I asked and they ordered them in to my local branch for today.

Hi Ian , I think that Toyo R888 are best value for road legal track tyres , plenty of previous discussion threads on this and GT3 forum.

The Michelins are expensive and do not last as long , they start off with not much tread depth , they do provide superior grip level , they are not as sure footed in wet conditions cf Toyos.

Using old SO2s on track days is better than using new SO2s on track days !!! There is less block depth to squirm and overheat by hysteresis......if you are pushing hard then you can get chunks of rubber coming off like pizza cheese [:D]

My N rated road tyre of choice is Michelin Pilot Sport , the compound and tread design stands up pretty well to occasional track use and does not melt down like the Bridgestones.
 
Thanks oldtimer,

Plan is to use the brand new SO2 as my daily road tyre, giving hopefully good wet and dry weather grip - it doesn't have to provide race track grip on the A46 / M69 :)

The two rear MPSC will be binned as no tread left, and the two fronts kept to one side for now.

Come spring, I will have a choice of using my spare Cup wheels and part work old SO2 for track days, or if finance permits, I will buy a new set of track only tyres - any more votes for R888 ?

yes, its what I use. Out right grip is pretty good, cost is nearly palatable. Wear is OK. There are stickier tyres but for trackdays - will be fine.
 
Another +1 for the R888s, although Toyo keep putting the price up and making them more difficult to get hold of. I'm also tempted to try the Kumho V70a at some point, or the Dunlop DZ03.
 
Just had the new road use SO2 fitted today, so will now wait until Spring to search out the best deal on a set of track tyres to go on my spare set of Cup Wheels.

Thanks for the input.
